The reflex activator was bandpass noise from 2,500 to 11,000 Hz presented at a maximum spectrum level\n of 51 dB SPL measured in the ear canal. Reflexes were detected by calculating a cross-correlation between one-twelfth-octave measurements of YR for the highest activator level and responses to lower levels. The reflex-induced shifts in YR for the infant ears were similar in pattern to adult\n responses but were noisy at frequencies below 1000 Hz. Infant reflexes were more successfully detected when the cross-correlation was calculated from 1000 to 8000 Hz, whereas adult reflexes were more successfully detected for a cross-correlation from 250 to 2000 Hz. This method may be useful\n in capturing the most robust frequency region for acoustic reflex detection across postnatal middle ear development. Este estudio examin\u00f3 las medidas del reflejo ac\u00fastico estapedial contralateral en adultos e infantes de seis semanas de edad, utilizando cambios de banda ancha\n en la admitancia y en la reflectancia de la energ\u00eda (YR). El activador del reflejo fue un ruido de pasabanda desde 2.500 a 11.000 Hz, presentado a un nivel espectral m\u00e1ximo de 51 dB SPL, medido en el canal auditivo. Los reflejos fueron detectados calculando una correlaci\u00f3n\n cruzada entre una medici\u00f3n de un duod\u00e9cimo de octava del YR para la intensidad m\u00e1s alta del activador y las respuestas para el nivel m\u00e1s bajo. Los cambios inducidos por el reflejo en el YR para los o\u00eddos de los infantes tuvieron un patr\u00f3n similar a\n las respuestas de los adultos pero estuvieron interferidos por ruido a frecuencias por debajo de 1000 Hz. Los reflejos de los infantes fueron mejor detectados cuando la correlaci\u00f3n cruzada se calcul\u00f3 de 1.000 a 8.000 Hz, mientras que los reflejos de los adultos de detectaron\n mejor con correlaciones cruzadas desde 250 a 2.000 Hz. Este m\u00e9todo puede ser \u00fatil para la identificaci\u00f3n de la regi\u00f3n frecuencial m\u00e1s robusta en la detecci\u00f3n del reflejo ac\u00fastico, durante el desarrollo post-natal del o\u00eddo medio.<\/jats:p>","DOI":"10.3766\/jaaa.16.5.3","type":"journal-article","created":{"date-parts":[[2008,4,22]],"date-time":"2008-04-22T23:54:28Z","timestamp":1208908468000},"page":"278-290","source":"Crossref","is-referenced-by-count":20,"title":["Detection of the Acoustic Stapedius Reflex in Infants Using Wideband Energy Reflectance and Admittance"],"prefix":"10.3766","volume":"16","author":[{"given":"Patrick M.","family":"Feeney","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chris A.","family":"Sanford","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2087","container-title":["Journal of the American Academy of Audiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ingentaconnect.com\/content\/aaa\/jaaa\/2005\/00000016\/00000005\/art00003","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,5]],"date-time":"2025-02-05T23:12:26Z","timestamp":1738797146000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ingentaconnect.com\/content\/10.3766\/jaaa.16.5.3"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2005,5,1]]},"references-count":0,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2005,5,1]]}},"alternative-id":["1050-0545(20050501)16:5L.278;1-"],"URL":"https:\/\/doi.org\/10.3766\/jaaa.16.5.3","relation":{},"ISSN":["1050-0545"],"issn-type":[{"value":"1050-0545","type":"print"}],"subject":[],"published":{"date-parts":[[2005,5,1]]}}}
