As open-canal fittings have become increasingly popular in the recent past, so has the debate\n about the effective directional benefit available from these devices. <jats:bold>Purpose:<\/jats:bold> This study investigates the benefit of directional microphones in two commercially available open-canal behind-the-ear hearing aids using the Hearing in Noise Test (HINT). <jats:bold>Study Sample:<\/jats:bold> Sixteen individuals,\n between 50 and 85 year of age, with high-frequency bilateral sensorineural hearing loss and no previous hearing aid experience participated in this study. <jats:bold>Data Collection and Analysis:<\/jats:bold> Data Collection and Analysis: Individuals were asked to repeat sentences (presented at 0\u00b0 azimuth)\n in the presence of a diffuse-field uncorrelated broadband speech-shaped noise. HINT performance was compared across hearing instruments and conditions using a linear model with repeated measures. <jats:bold>Results:<\/jats:bold> There was a directional advantage of 2.6 dB as compared to the unaided condition.\n Average performance was worse in the omnidirectional mode as compared to the unaided condition. <jats:bold>Conclusions:<\/jats:bold> These results suggest that directional signal processing should not be precluded in open-canal instruments for listening in noisy environments.<\/jats:p>","DOI":"10.3766\/jaaa.19.7.7","type":"journal-article","created":{"date-parts":[[2009,3,14]],"date-time":"2009-03-14T14:29:02Z","timestamp":1237040942000},"page":"571-578","source":"Crossref","is-referenced-by-count":12,"title":["Speech Perception in Noise Using Directional Microphones in Open-Canal Hearing Aids"],"prefix":"10.3766","volume":"19","author":[{"given":"Emily J.","family":"Klemp","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sumitrajit","family":"Dhar","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\/2008\/00000019\/00000007\/art00009","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,6]],"date-time":"2025-02-06T07:55:34Z","timestamp":1738828534000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ingentaconnect.com\/content\/10.3766\/jaaa.19.7.7"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,7,1]]},"references-count":0,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2008,7,1]]}},"alternative-id":["1050-0545(20080701)19:7L.571;1-"],"URL":"https:\/\/doi.org\/10.3766\/jaaa.19.7.7","relation":{},"ISSN":["1050-0545"],"issn-type":[{"value":"1050-0545","type":"print"}],"subject":[],"published":{"date-parts":[[2008,7,1]]}}}
