The target formula was selected as NAL-NL1 in the programming software of four types of digital hearing aids. REIG measurements on 42 ears showed that 64% of cases failed to come within \u00b110 dB of the target at one or more of\n the following frequencies: 0.25, 0.5, 0.75, 1, 1.5, 2, and 4 kHz. After adjusting the frequency-gain response of the aids, based on the REIG results, 83% of cases came within \u00b110 dB of the target. The target was met more often, both before and after adjustment, for aids with seven gain\n \u201chandles\u201d than for aids with four gain \u201chandles.\u201d The results indicate that REIG measurements can and should be used to achieve more accurate fittings but that accurate adjustments are difficult with some aids. Los prop\u00f3sitos principales de este estudio fueron:\n (1) determinar si las mediciones rutinarias de ganancia de inserci\u00f3n en o\u00eddo real (REIG) son necesarias para adaptar auxiliares auditivos digitales; y (2) evaluar el grado en que la modificaci\u00f3n de la respuesta de ganancia por frecuencia de un auxiliar puede llevar a mejores\n ajustes en los casos donde la ganancia meta no le logr\u00f3 inicialmente. La f\u00f3rmula meta fue seleccionada como la NAL-NL1 en el software de programaci\u00f3n de cuatro tipo de auxiliares auditivos digitales. Las mediciones del REIG en 42 o\u00eddos mostr\u00f3 que el 64% de\n los casos fallaron en acercarse a \u00b1 10 dB de la meta, en una o m\u00e1s de las siguientes frecuencias: 0.25, 0.5, 0.75, 1, 1.5, 2, y 4 kHz. Luego de ajustar la respuesta de ganancia por frecuencia, con base en los resultados del REIG, 83% de los casos se acercaron a \u00b1 10 dB\n de la meta. La meta fue alcanzada m\u00e1s a menudo, tanto antes y despu\u00e9s del ajuste, para auxiliares con siete ajustes de ganancia que para auxiliares con cuatro ajustes. Los resultados indican que las mediciones de REIG pueden y deber\u00edan ser utilizadas para lograr adaptaciones\n m\u00e1s exactas, pero que tales ajustes exactos son dif\u00edciles en algunos auxiliares.<\/jats:p>","DOI":"10.3766\/jaaa.18.8.3","type":"journal-article","created":{"date-parts":[[2008,4,22]],"date-time":"2008-04-22T19:54:28Z","timestamp":1208894068000},"page":"653-664","source":"Crossref","is-referenced-by-count":53,"title":["The Value of Routine Real Ear Measurement of the Gain of Digital Hearing Aids"],"prefix":"10.3766","volume":"18","author":[{"given":"Hashir","family":"Aazh","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian C.J.","family":"Moore","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\/2007\/00000018\/00000008\/art00003","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,5]],"date-time":"2025-02-05T18:16:08Z","timestamp":1738779368000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ingentaconnect.com\/content\/10.3766\/jaaa.18.8.3"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,9,1]]},"references-count":0,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2007,9,1]]}},"alternative-id":["1050-0545(20070901)18:8L.653;1-"],"URL":"https:\/\/doi.org\/10.3766\/jaaa.18.8.3","relation":{},"ISSN":["1050-0545"],"issn-type":[{"value":"1050-0545","type":"print"}],"subject":[],"published":{"date-parts":[[2007,9,1]]}}}
