On peut la voir comme une carte qui nous permet de comprendre l\u2019exp\u00e9rience auditive d\u2019une personne. Avant de comprendre la carte, il faut d\u2019abord comprendre comment fonctionne notre audition.<\/p>\n<h2>Comment entendons-nous\u2009? Une revue rapide.<\/h2>\n<p>Le son est une vibration qui fait r\u00e9agir la partie de l\u2019oreille qui entend. La plupart des gens ne sont pas au courant que nous entendons par deux chemins ou m\u00e9canismes. Le chemin a\u00e9rien et le chemin osseux. La plupart des gens ont d\u00e9j\u00e0 entendu parler du chemin a\u00e9rien, soit le chemin naturel du son passant par le conduit auditif jusqu\u2019au cerveau en passant par l\u2019oreille moyenne et interne.<\/p>\n<p>L\u2019oreille interne contient l\u2019organe de l\u2019audition, la cochl\u00e9e. Les cochl\u00e9es des deux oreilles sont install\u00e9es dans le cr\u00e2ne. L\u2019os \u00e9tant un bon conducteur de vibration, lorsqu\u2019un c\u00f4t\u00e9 vibre, l\u2019autre aussi. C\u2019est donc le cas des deux cochl\u00e9es. C\u2019est ainsi que se passe le deuxi\u00e8me chemin du son. On entend par les vibrations de l\u2019os qui sont transmises \u00e0 la cochl\u00e9e.<\/p>\n<p>Les vibrations m\u00e9caniques (sons) sont ensuite transform\u00e9es en messages \u00e9lectriques qui sont envoy\u00e9s au cerveau pour \u00eatre comprises. La conduction osseuse saute l\u2019\u00e9tape de l\u2019oreille moyenne et se rend directement \u00e0 l\u2019oreille interne.<\/p>\n<h2>L\u2019audiogramme<\/h2>\n<p>L\u2019audiogramme est le graphique qui permet de repr\u00e9senter le niveau d\u2019audition de quelqu\u2019un. Une fois le test r\u00e9alis\u00e9, les r\u00e9ponses sont plac\u00e9es dans le graphique pour cr\u00e9er la carte de ce que la personne entend. Pour en apprendre plus sur les tests auditifs, cliquer ici.<\/p>\n<p>Regardons maintenant l\u2019audiogramme de plus pr\u00e8s.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone wp-image-5345\" src=\"https:\/\/becausesoundmatters.ca\/wp\/wp-content\/uploads\/2020\/08\/blogpic1-267x300.jpg\" alt=\"\" width=\"475\" height=\"533\" srcset=\"https:\/\/becausesoundmatters.ca\/wp\/wp-content\/uploads\/2020\/08\/blogpic1-267x300.jpg 267w, https:\/\/becausesoundmatters.ca\/wp\/wp-content\/uploads\/2020\/08\/blogpic1-768x863.jpg 768w, https:\/\/becausesoundmatters.ca\/wp\/wp-content\/uploads\/2020\/08\/blogpic1-600x674.jpg 600w, https:\/\/becausesoundmatters.ca\/wp\/wp-content\/uploads\/2020\/08\/blogpic1.jpg 780w\" sizes=\"(max-width: 475px) 100vw, 475px\" \/><\/p>\n<p>On peut voir les fr\u00e9quences test\u00e9es sur l\u2019axe horizontal. Les sons graves sont \u00e0 gauche (basses fr\u00e9quences) et comme un piano, on monte jusqu\u2019aux sons aigus (hautes fr\u00e9quences), \u00e0 droite.<\/p>\n<p>L\u2019axe vertical repr\u00e9sente les niveaux de pr\u00e9sentation (volume) des sons envoy\u00e9s des sons faibles (en haut du graphique) aux sons forts (en bas du graphique). Les niveaux de pr\u00e9sentations des sons sont mesur\u00e9s en d\u00e9cibels (dB HL).<\/p>\n<p>Certains audiogrammes pr\u00e9sentent \u00e9galement une zone ombr\u00e9e en forme de banane au milieu du graphique. C&#039;est ce qu&#039;on appelle la banane vocale. Elle englobe tous les sons de la parole que nous entendons, la fr\u00e9quence \u00e0 laquelle nous les entendons et leur intensit\u00e9 dans chaque discours.<\/p>\n<p>Avoir la banane vocale sur un audiogramme peut \u00eatre un outil utile car l&#039;audiologiste peut voir visuellement quels sons de la parole sont audibles et lesquels ne le sont pas en fonction de la fa\u00e7on dont les seuils auditifs d&#039;un individu sont cartographi\u00e9s sur la partie banane vocale de l&#039;audiogramme.<\/p>\n<p>Le son le plus faible son qui peut \u00eatre entendu par une personne d\u00e9termine son degr\u00e9 d\u2019audition. C\u2019est ce qu\u2019on appelle le seuil. Ces seuils sont mesur\u00e9s pour diff\u00e9rentes fr\u00e9quences.<\/p>\n<p>Les personnes ayant une audition normale ont des seuils tr\u00e8s bas, entre 0 et 20 dB*. Ainsi, lorsque les symboles apparaissent en haut du graphique, cela indique que le volume n&#039;avait pas besoin d&#039;\u00eatre tr\u00e8s fort pour que le patient l&#039;entende. Lorsque les symboles migrent vers le bas du graphique, cela indique que les sons devaient \u00eatre pr\u00e9sent\u00e9s \u00e0 des volumes plus forts avant que le patient n&#039;indique qu&#039;il entendait quelque chose.<\/p>\n<p>Selon l\u2019emplacement des symboles sur le graphique on peut dire que : l\u2019audition est normale lorsque les seuils sont meilleurs que 20 dB HL (en haut du graphique) ou encore qu\u2019il y a une perte l\u00e9g\u00e8re lorsqu\u2019ils sont entre 21 et 40 dB HL, mod\u00e9r\u00e9e entre 41 et 60 dB, s\u00e9v\u00e8re de 61 \u00e0 80 dB HL et profonde au-dessus de 80 dB HL*.<\/p>\n<h2>Les symboles<\/h2>\n<p>Revenons maintenant aux symboles. Les \u2018X\u2019 et \u2018O\u2019 repr\u00e9sentent ce qui est entendu par la voie a\u00e9rienne et les \u2018\u2019 repr\u00e9sentent ce qui est entendu par la voie osseuse. Les couleurs bleu et rouge ne sont pas les seules informations qui nous disent de quelle oreille on parle. Ainsi les \u2018X\u2019 et les \u2018\u2019 repr\u00e9sentent l\u2019oreille droite.<\/p>\n<p>Les r\u00e9ponses du patient par conduction osseuse sont indiqu\u00e9es par \u00ab &gt; \u00bb pour l&#039;oreille gauche et \u00ab &lt; \u00bb pour l&#039;oreille droite. En plus des diff\u00e9rents symboles, les audiologistes peuvent utiliser la couleur bleue pour indiquer les r\u00e9ponses de l&#039;oreille gauche et la couleur rouge pour celles de l&#039;oreille droite.<\/p>\n<p>Les seuils osseux ne sont pas toujours test\u00e9s. Lorsqu\u2019ils le sont, c\u2019est pour d\u00e9terminer \u00e0 quel endroit le son a de la difficult\u00e9 \u00e0 passer. Par exemple, si les \u2018X\u2019 ou les \u2018O\u2019 se situent vers le bas du graphique , on veut savoir si le son est bloqu\u00e9 \u00e0 l\u2019oreille externe\/moyenne ou si le probl\u00e8me est au niveau de l\u2019oreille interne. Toutefois, chez une personne avec une audition dans la normale, il n\u2019est pas n\u00e9cessaire de chercher l\u2019origine de la perte auditive puisqu\u2019il n\u2019y en a pas.<\/p>\n<p>G\u00e9n\u00e9ralement, lorsqu\u2019une perte auditive est pr\u00e9sente, il faudra s\u2019assurer que tester les deux oreilles s\u00e9par\u00e9ment. \u00c7a peut para\u00eetre simple, mais en r\u00e9alit\u00e9, le son peut nous jouer des tours. En effet, puisque le cr\u00e2ne est un bon conducteur, une partie du son envoy\u00e9 par l\u2019\u00e9couteur peut se rendre jusqu\u2019\u00e0 l\u2019autre oreille par voie osseuse. On peut donc envoyer un son \u00e0 l\u2019oreille droite et que ce soit l\u2019oreille gauche qui l\u2019entende! Pour \u00e9viter ce ph\u00e9nom\u00e8ne, l\u2019audiologiste pourrait utiliser un bruit de fond pr\u00e9sent\u00e9 \u00e0 une oreille pour \u00e9viter que celle-ci entende les sons. C\u2019est ce qu\u2019on appelle le masquage.. On repr\u00e9sente alors les seuils a\u00e9riens masqu\u00e9s \u00e0 gauche par \u2018\u25a1\u2009\u00bb et \u00e0 droite par \u2018\u2206\u2019. Pour les seuils osseux masqu\u00e9s, on les repr\u00e9sente \u00e0 gauche par \u2018[\u2018et \u00e0 droite par \u2018]\u2019.<\/p>\n<h2>Lire la carte<\/h2>\n<p>Maintenant que vous comprenez comment est cr\u00e9\u00e9 l\u2019audiogramme et que vous pouvez le lire, il est temps de d\u00e9terminer l\u2019exp\u00e9rience auditive de la personne. Si elle pr\u00e9sente une perte auditive, l\u2019audiologiste peut alors comprendre et expliquer le comment et le pourquoi des difficult\u00e9s \u00e0 entendre. La repr\u00e9sentation visuelle de ces difficult\u00e9s peut alors \u00eatre utile pour bien faire comprendre le tout.<\/p>\n<p>Si le patient est diagnostiqu\u00e9 avec une perte auditive, en fonction du degr\u00e9 de perte, l&#039;audiologiste peut comprendre comment et pourquoi il peut avoir des difficult\u00e9s d&#039;audition. L&#039;audiologiste doit toujours expliquer les r\u00e9sultats en d\u00e9tail au patient et c&#039;est l\u00e0 qu&#039;une repr\u00e9sentation visuelle de l&#039;audiogramme s&#039;av\u00e8re utile !<\/p>\n<p>L\u2019audiologiste peut aussi expliquer comment la perte auditive peut effectuer le quotidien de la personne et ses interactions avec le monde qui l\u2019entoure. Selon les difficult\u00e9s \u00e9prouv\u00e9es par le patient et le degr\u00e9 de sa perte auditive, des appareils auditifs peuvent \u00eatre recommand\u00e9s.<\/p>\n<h2>Maintenant, vous pourrez lire votre audiogramme.<\/h2>\n<p>Bref, rappelez-vous que si vous sentez que vous n\u2019entendez pas comme avant, si vous avez de la difficult\u00e9 \u00e0 suivre les conversations ou si vous faites r\u00e9p\u00e9ter, l\u2019audiologiste peut vous aider.<\/p>\n<p>*de l\u00e9g\u00e8res diff\u00e9rences de l\u2019ordre de 5 dB peuvent survenir entre les professionnels quant aux limites d\u00e9limitant chaque niveau de perte.<\/p>\n<p>\u00a0<\/p>\n\n\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>An audiogram is a visual representation of one\u2019s hearing ability. You can think of it as a map that helps us understand someone\u2019s hearing experience. In order to understand how this map works, we need to review how our auditory (hearing) system functions. How we Hear \u2013 Quick Overview When an object moves, it creates a vibration in the air that travels outwards in all directions until it reaches an ear where the sound can be heard. Most people are not aware that there are two pathways\/mechanisms at work that contribute to how people hear: air conduction and bone conduction. Most people are familiar with air conduction hearing in which sound travels naturally down your ear canal to the middle ear onto the inner ear and then up to the brain. The inner ear contains the main hearing organ known as a cochlea. Both cochleae are encased within the temporal bone of the skull. Bone is a very good conductor so when the skull vibrates, so do both cochleae. This leads us to the second mechanism of hearing through bone conduction where vibrations of the skull get directly transferred to the cochlea. Here, the mechanical vibrations (sounds) are converted into electrical impulses to be sent up to the brain for processing. Bone conduction hearing bypasses the outer and middle ear and gets straight to business in the inner ear. The Audiogram An audiogram is a graphical representation of an individual\u2019s hearing levels. After a hearing test is conducted in which both the air conduction and bone conduction pathways are tested, the results are mapped onto the audiogram. To learn more about how hearing is tested click here. Let\u2019s take a look at the audiogram now. Along the horizontal axis of the audiogram you can see the range of frequencies that are typically tested. Low frequencies can be seen on the left side (bass) moving to high frequencies on the right (treble), similar to a piano. The vertical axis represents the presentation level (volume) of the tones by the audiologist from very quiet at the top to very loud at the bottom. The presentation level of the tones is in dB HL (decibels, hearing level). Some audiograms also have a banana-shaped shaded area in the middle of the graph. This is known as the speech banana. It encompasses all of the speech sounds that we hear, at what frequency we hear them and how loud they are in every speech. Having the speech banana on an audiogram can be a useful tool as the audiologist can visually see which speech sounds are audible and which are not based on how an individual\u2019s hearing thresholds are mapped out on the speech banana portion of the audiogram. After testing is complete the results from the hearing test will be graphed onto the audiogram using several different symbols. These symbols indicate hearing thresholds. A threshold is the quietest sound that an individual can hear at a given frequency. Individuals with normal hearing have very low thresholds between 0-20dB*. So, when the symbols appear at the top of the graph it indicates that the volume did not need to be very loud for the patient to hear it. As the symbols migrate towards the bottom of the graph, it shows that the tones needed to be presented at louder volumes before the patient indicated that they heard something. The location of the symbols on the graph will depict the degree of hearing loss an individual may have. Above 20dB is within normal range, between 20-40dB is a mild hearing loss, 40 \u2013 55dB is moderate, 55-70dB is moderately severe, 70-90dB is severe and beyond 90dB represents a profound hearing loss*. The Symbols Audiologists use \u2018X\u2019s to represent left ear thresholds and \u2018O\u2019s to represent the right ear thresholds. The \u2018X\u2019 and \u2018O\u2019 represent the results from air conduction testing. Recall that if a hearing loss is identified &#8211; the \u2018X\u2019s and \u2018O\u2019s are lower down on the audiogram &#8211; bone conduction testing needs to be completed to determine where the problem is occurring (middle ear or inner ear). Patient responses by bone conduction are denoted by \u2018&gt;\u2019 for the left ear and \u2018&lt;\u2019 for the right. In addition to the different symbols, audiologists may use the colour blue to indicate left ear responses and red for the right ear responses. In some cases, an additional noise may be presented to one ear during bone conduction testing. Since the skull is such a good conductor, the vibrations of the oscillator will stimulate BOTH cochlea (left and right). Therefore, in order to determine which cochlea is responding the additional noise allows us to keep the non-test ear \u201cbusy\u201d to ensure it isn\u2019t \u201chelping out\u201d the ear currently being tested. This is called masking and it allows the audiologist to isolate each cochlea separately. The symbols to denote these masked responses are \u2018]\u2019 for the left ear and \u2018[\u2018 for the right. Interpreting the Map Now that you understand how the audiogram is created and how to read it, it is time to interpret it to get an understanding of the patient\u2019s hearing experience. If the patient is identified with a hearing loss, depending on the degree of loss, the audiologist can understand how and why they may be struggling with their hearing. The audiologist should always explain the results in detail with the patient and this is where having the visual representation of the audiogram comes in handy! The audiologist should also explain how the hearing loss can affect the patient\u2019s day-to-day interactions with the world. Depending on the patient\u2019s difficulties and the level of hearing loss, treatment in the form of hearing aids may be recommended. Now you should be able to read your audiogram! Remember, if you feel you are not hearing as well, struggling to follow conversations, or have difficulty hearing the TV you should contact your local audiologist for help. Getting a hearing test is the first step towards better hearing. *there [&hellip;]<\/p>","protected":false},"author":2,"featured_media":5342,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[77],"tags":[87,88,86,93,89,90,193],"class_list":["post-5471","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-audiology","tag-audiogram","tag-audiologist","tag-decibel","tag-hearing","tag-hearing-loss","tag-hearing-test","tag-resources"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.0 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>A Map of your Hearing - because sound matters<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/becausesoundmatters.ca\/fr\/a-map-of-your-hearing\" \/>\n<meta property=\"og:locale\" content=\"fr_FR\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"A Map of your Hearing - because sound matters\" \/>\n<meta property=\"og:description\" content=\"An audiogram is a visual representation of one\u2019s hearing ability.

You can think of it as a map that helps us understand someone\u2019s hearing experience. In order to understand how this map works, we need to review how our auditory (hearing) system functions. How we Hear \u2013 Quick Overview When an object moves, it creates a vibration in the air that travels outwards in all directions until it reaches an ear where the sound can be heard. Most people are not aware that there are two pathways\/mechanisms at work that contribute to how people hear: air conduction and bone conduction. Most people are familiar with air conduction hearing in which sound travels naturally down your ear canal to the middle ear onto the inner ear and then up to the brain. The inner ear contains the main hearing organ known as a cochlea. Both cochleae are encased within the temporal bone of the skull. Bone is a very good conductor so when the skull vibrates, so do both cochleae. This leads us to the second mechanism of hearing through bone conduction where vibrations of the skull get directly transferred to the cochlea. Here, the mechanical vibrations (sounds) are converted into electrical impulses to be sent up to the brain for processing. Bone conduction hearing bypasses the outer and middle ear and gets straight to business in the inner ear. The Audiogram An audiogram is a graphical representation of an individual\u2019s hearing levels. After a hearing test is conducted in which both the air conduction and bone conduction pathways are tested, the results are mapped onto the audiogram. To learn more about how hearing is tested click here. Let\u2019s take a look at the audiogram now. Along the horizontal axis of the audiogram you can see the range of frequencies that are typically tested. Low frequencies can be seen on the left side (bass) moving to high frequencies on the right (treble), similar to a piano. The vertical axis represents the presentation level (volume) of the tones by the audiologist from very quiet at the top to very loud at the bottom. The presentation level of the tones is in dB HL (decibels, hearing level). Some audiograms also have a banana-shaped shaded area in the middle of the graph. This is known as the speech banana. It encompasses all of the speech sounds that we hear, at what frequency we hear them and how loud they are in every speech. Having the speech banana on an audiogram can be a useful tool as the audiologist can visually see which speech sounds are audible and which are not based on how an individual\u2019s hearing thresholds are mapped out on the speech banana portion of the audiogram. After testing is complete the results from the hearing test will be graphed onto the audiogram using several different symbols. These symbols indicate hearing thresholds. A threshold is the quietest sound that an individual can hear at a given frequency. Individuals with normal hearing have very low thresholds between 0-20dB*. So, when the symbols appear at the top of the graph it indicates that the volume did not need to be very loud for the patient to hear it. As the symbols migrate towards the bottom of the graph, it shows that the tones needed to be presented at louder volumes before the patient indicated that they heard something. The location of the symbols on the graph will depict the degree of hearing loss an individual may have. Above 20dB is within normal range, between 20-40dB is a mild hearing loss, 40 \u2013 55dB is moderate, 55-70dB is moderately severe, 70-90dB is severe and beyond 90dB represents a profound hearing loss*. The Symbols Audiologists use \u2018X\u2019s to represent left ear thresholds and \u2018O\u2019s to represent the right ear thresholds. The \u2018X\u2019 and \u2018O\u2019 represent the results from air conduction testing. Recall that if a hearing loss is identified &#8211; the \u2018X\u2019s and \u2018O\u2019s are lower down on the audiogram &#8211; bone conduction testing needs to be completed to determine where the problem is occurring (middle ear or inner ear). Patient responses by bone conduction are denoted by \u2018&gt;\u2019 for the left ear and \u2018&lt;\u2019 for the right. In addition to the different symbols, audiologists may use the colour blue to indicate left ear responses and red for the right ear responses. In some cases, an additional noise may be presented to one ear during bone conduction testing. Since the skull is such a good conductor, the vibrations of the oscillator will stimulate BOTH cochlea (left and right). Therefore, in order to determine which cochlea is responding the additional noise allows us to keep the non-test ear \u201cbusy\u201d to ensure it isn\u2019t \u201chelping out\u201d the ear currently being tested. This is called masking and it allows the audiologist to isolate each cochlea separately. The symbols to denote these masked responses are \u2018]\u2019 for the left ear and \u2018[\u2018 for the right. Interpreting the Map Now that you understand how the audiogram is created and how to read it, it is time to interpret it to get an understanding of the patient\u2019s hearing experience. If the patient is identified with a hearing loss, depending on the degree of loss, the audiologist can understand how and why they may be struggling with their hearing. The audiologist should always explain the results in detail with the patient and this is where having the visual representation of the audiogram comes in handy! The audiologist should also explain how the hearing loss can affect the patient\u2019s day-to-day interactions with the world. Depending on the patient\u2019s difficulties and the level of hearing loss, treatment in the form of hearing aids may be recommended. Now you should be able to read your audiogram! Remember, if you feel you are not hearing as well, struggling to follow conversations, or have difficulty hearing the TV you should contact your local audiologist for help. Getting a hearing test is the first step towards better hearing. *there [&hellip;]","og_url":"https:\/\/becausesoundmatters.ca\/fr\/a-map-of-your-hearing","og_site_name":"because sound matters","article_published_time":"2020-08-18T19:14:02+00:00","article_modified_time":"2020-11-27T18:23:44+00:00","og_image":[{"width":1200,"height":1200,"url":"https:\/\/becausesoundmatters.ca\/wp\/wp-content\/uploads\/2020\/08\/compass-on-a-city-map-PB9TS58.jpg","type":"image\/jpeg"}],"author":"The Audiology Team","twitter_card":"summary_large_image","twitter_misc":{"\u00c9crit par":"The Audiology Team","Dur\u00e9e de lecture estim\u00e9e":"5 minutes"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"WebPage","@id":"https:\/\/becausesoundmatters.ca\/fr\/a-map-of-your-hearing","url":"https:\/\/becausesoundmatters.ca\/fr\/a-map-of-your-hearing","name":"A Map of your Hearing - because sound matters","isPartOf":{"@id":"https:\/\/becausesoundmatters.ca\/#website"},"primaryImageOfPage":{"@id":"https:\/\/becausesoundmatters.ca\/fr\/a-map-of-your-hearing#primaryimage"},"image":{"@id":"https:\/\/becausesoundmatters.ca\/fr\/a-map-of-your-hearing#primaryimage"},"thumbnailUrl":"https:\/\/becausesoundmatters.ca\/wp\/wp-content\/uploads\/2020\/08\/compass-on-a-city-map-PB9TS58.jpg","datePublished":"2020-08-18T19:14:02+00:00","dateModified":"2020-11-27T18:23:44+00:00","author":{"@id":"https:\/\/becausesoundmatters.ca\/#\/schema\/person\/73567234a51148d3c6bec25ea238edc5"},"breadcrumb":{"@id":"https:\/\/becausesoundmatters.ca\/fr\/a-map-of-your-hearing#breadcrumb"},"inLanguage":"fr-FR","potentialAction":[{"@type":"ReadAction","target":["https:\/\/becausesoundmatters.ca\/fr\/a-map-of-your-hearing"]}]},{"@type":"ImageObject","inLanguage":"fr-FR","@id":"https:\/\/becausesoundmatters.ca\/fr\/a-map-of-your-hearing#primaryimage","url":"https:\/\/becausesoundmatters.ca\/wp\/wp-content\/uploads\/2020\/08\/compass-on-a-city-map-PB9TS58.jpg","contentUrl":"https:\/\/becausesoundmatters.ca\/wp\/wp-content\/uploads\/2020\/08\/compass-on-a-city-map-PB9TS58.jpg","width":1200,"height":1200,"caption":"Compass on a city map"},{"@type":"BreadcrumbList","@id":"https:\/\/becausesoundmatters.ca\/fr\/a-map-of-your-hearing#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/becausesoundmatters.ca\/"},{"@type":"ListItem","position":2,"name":"A Map of your Hearing"}]},{"@type":"WebSite","@id":"https:\/\/becausesoundmatters.ca\/#website","url":"https:\/\/becausesoundmatters.ca\/","name":"because sound matters","description":"Juste un autre site WordPress","potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/becausesoundmatters.ca\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"fr-FR"},{"@type":"Person","@id":"https:\/\/becausesoundmatters.ca\/#\/schema\/person\/73567234a51148d3c6bec25ea238edc5","name":"L'\u00e9quipe d'audiologie","image":{"@type":"ImageObject","inLanguage":"fr-FR","@id":"https:\/\/becausesoundmatters.ca\/#\/schema\/person\/image\/","url":"https:\/\/secure.gravatar.com\/avatar\/09748ed75aa427cc75aa6555f270a187?s=96&d=mm&r=g","contentUrl":"https:\/\/secure.gravatar.com\/avatar\/09748ed75aa427cc75aa6555f270a187?s=96&d=mm&r=g","caption":"The Audiology Team"},"url":"https:\/\/becausesoundmatters.ca\/fr\/author\/admin"}]}},"_links":{"self":[{"href":"https:\/\/becausesoundmatters.ca\/fr\/wp-json\/wp\/v2\/posts\/5471","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/becausesoundmatters.ca\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/becausesoundmatters.ca\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/becausesoundmatters.ca\/fr\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/becausesoundmatters.ca\/fr\/wp-json\/wp\/v2\/comments?post=5471"}],"version-history":[{"count":10,"href":"https:\/\/becausesoundmatters.ca\/fr\/wp-json\/wp\/v2\/posts\/5471\/revisions"}],"predecessor-version":[{"id":6169,"href":"https:\/\/becausesoundmatters.ca\/fr\/wp-json\/wp\/v2\/posts\/5471\/revisions\/6169"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/becausesoundmatters.ca\/fr\/wp-json\/wp\/v2\/media\/5342"}],"wp:attachment":[{"href":"https:\/\/becausesoundmatters.ca\/fr\/wp-json\/wp\/v2\/media?parent=5471"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/becausesoundmatters.ca\/fr\/wp-json\/wp\/v2\/categories?post=5471"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/becausesoundmatters.ca\/fr\/wp-json\/wp\/v2\/tags?post=5471"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
