No significant\n age or gender effects were found for tympanometric peak pressure. Peak Y<jats:sub>tm<\/jats:sub> measures, however, decreased with age in the left ear only across all age groups and were consistently higher for men than for women. After allowing for hearing loss, the effect of age on ASR thresholds was\n inconsistent. An increase in ASR thresholds with age was observed at selected frequencies but only when measured contralaterally, and these changes were not clinically significant. Overall, our findings suggest that current normative data for peak Y<jats:sub>tm<\/jats:sub> is too restricted for application\n in the older population, but there is insufficient evidence to warrant alternative normative data for the ASR threshold range in this same population. Se obtuvo la presi\u00f3n timpanom\u00e9trica pico, el pico de admitancia ac\u00fastica est\u00e1tica compensada (pico Y<jats:sub>tm<\/jats:sub>)\n y los umbrales de reflejo ac\u00fastico estapedial (ASR), para una muestra representativa de 1565 australianos viejos que participaban en el Estudio Auditivo de las Monta\u00f1as Azules (BMHS). No se encontraron efectos significativos de la edad o g\u00e9nero en los picos de presi\u00f3n\n timpanom\u00e9trica. Las mediciones de pico Y<jats:sub>tm<\/jats:sub>, sin embargo, disminuyeron con la edad s\u00f3lo en el o\u00eddo izquierdo, en todos los grupos, y fue consistentemente mayor en hombres que en mujeres. Luego de corregir de acuerdo a la p\u00e9rdida auditiva, el efecto de\n la edad sobre los umbrales de los ASR fue inconsistente. Se observ\u00f3 un aumento con la edad en los umbrales de los ASR en frecuencias seleccionadas, aunque s\u00f3lo cuando se med\u00eda contralateralmente, y estos cambios no fueron cl\u00ednicamente significativos. Globalmente,\n nuestros hallazgos sugieren que los datos normativos actuales para el pico Y<jats:sub>tm<\/jats:sub> son muy restrictivos para aplicar a las poblaciones m\u00e1s viejas, aunque existe evidencia insuficiente para garantizar datos normativos alternativos para el rango de umbrales de los ASR en esta misma\n poblaci\u00f3n.<\/jats:p>","DOI":"10.3766\/jaaa.18.5.4","type":"journal-article","created":{"date-parts":[[2008,4,22]],"date-time":"2008-04-22T23:54:28Z","timestamp":1208908468000},"page":"391-403","source":"Crossref","is-referenced-by-count":19,"title":["Tympanometric and Acoustic Stapedius Reflex Measures in Older Adults: The Blue Mountains Hearing Study"],"prefix":"10.3766","volume":"18","author":[{"given":"Maryanne","family":"Golding","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kathryn","family":"Doyle","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Doungkamol","family":"Sindhusake","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Mitchell","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philip","family":"Newall","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Hartley","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2087","container-title":["Journal of the American Academy of Audiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ingentaconnect.com\/content\/aaa\/jaaa\/2007\/00000018\/00000005\/art00004","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,5]],"date-time":"2025-02-05T23:15:54Z","timestamp":1738797354000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ingentaconnect.com\/content\/10.3766\/jaaa.18.5.4"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,5,1]]},"references-count":0,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2007,5,1]]}},"alternative-id":["1050-0545(20070501)18:5L.391;1-"],"URL":"https:\/\/doi.org\/10.3766\/jaaa.18.5.4","relation":{},"ISSN":["1050-0545"],"issn-type":[{"type":"print","value":"1050-0545"}],"subject":[],"published":{"date-parts":[[2007,5,1]]}}}
