A protocol for completing electroacoustic measures has not yet been validated for personal FM systems\n or digital modulation (DM) systems coupled to CI sound processors. In response, some professionals have used or altered the AAA electroacoustic verification steps for fitting FM systems to hearing aids when fitting FM systems to CI sound processors. More recently steps were outlined in a proposed\n protocol.<jats:bold>Purpose:<\/jats:bold>The purpose of this research is to review and compare the electroacoustic test measures outlined in a 2013 article by Schafer and colleagues in the <jats:italic>Journal of the American Academy of Audiology<\/jats:italic> titled \u201cA Proposed Electroacoustic Test Protocol for Personal\n FM Receivers Coupled to Cochlear Implant Sound Processors\u201d to the AAA electroacoustic verification steps for fitting FM systems to hearing aids when fitting DM systems to CI users.<jats:bold>Research Design:<\/jats:bold>Electroacoustic measures were conducted on 71 CI sound processors and Phonak Roger\n DM systems using a proposed protocol and an adapted AAA protocol. Phonak\u2019s recommended default receiver gain setting was used for each CI sound processor manufacturer and adjusted if necessary to achieve transparency.<jats:bold>Study Sample:<\/jats:bold>Electroacoustic measures were conducted on Cochlear\n and Advanced Bionics (AB) sound processors. In this study, 28 Cochlear Nucleus 5\/CP810 sound processors, 26 Cochlear Nucleus 6\/CP910 sound processors, and 17 AB Naida CI Q70 sound processors were coupled in various combinations to Phonak Roger DM dedicated receivers (25 Phonak Roger 14 receivers\u2014Cochlear\n dedicated receiver\u2014and 9 Phonak Roger 17 receivers\u2014AB dedicated receiver) and 20 Phonak Roger Inspiro transmitters.<jats:bold>Data Collection and Analysis:<\/jats:bold>Employing both the AAA and the Schafer et al protocols, electroacoustic measurements were conducted with the Audioscan Verifit\n in a clinical setting on 71 CI sound processors and Phonak Roger DM systems to determine transparency and verify FM advantage, comparing speech inputs (65 dB SPL) in an effort to achieve equal outputs. If transparency was not achieved at Phonak\u2019s recommended default receiver gain, adjustments\n were made to the receiver gain. The integrity of the signal was monitored with the appropriate manufacturer\u2019s monitor earphones.<jats:bold>Results:<\/jats:bold>Using the AAA hearing aid protocol, 50 of the 71 CI sound processors achieved transparency, and 59 of the 71 CI sound processors achieved transparency\n when using the proposed protocol at Phonak\u2019s recommended default receiver gain. After the receiver gain was adjusted, 3 of 21 CI sound processors still did not meet transparency using the AAA protocol, and 2 of 12 CI sound processors still did not meet transparency using the Schafer\n et al proposed protocol.<jats:bold>Conclusions:<\/jats:bold>Both protocols were shown to be effective in taking reliable electroacoustic measurements and demonstrate transparency. Both protocols are felt to be clinically feasible and to address the needs of populations that are unable to reliably report regarding\n the integrity of their personal DM systems.<\/jats:p>","DOI":"10.3766\/jaaa.16070","type":"journal-article","created":{"date-parts":[[2017,3,16]],"date-time":"2017-03-16T16:47:02Z","timestamp":1489682822000},"page":"625-635","source":"Crossref","is-referenced-by-count":1,"title":["Verification of a Proposed Clinical Electroacoustic Test Protocol for Personal Digital Modulation Receivers Coupled to Cochlear Implant Sound Processors"],"prefix":"10.3766","volume":"28","author":[{"given":"Erika L.","family":"Nair","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rhonda","family":"Sousa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shannon","family":"Wannagot","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\/2017\/00000028\/00000007\/art00004","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,6]],"date-time":"2025-02-06T08:05:35Z","timestamp":1738829135000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ingentaconnect.com\/content\/10.3766\/jaaa.16070"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,7,1]]},"references-count":0,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2017,7,1]]}},"alternative-id":["1050-0545(20170701)28:7L.625;1-"],"URL":"https:\/\/doi.org\/10.3766\/jaaa.16070","relation":{},"ISSN":["1050-0545"],"issn-type":[{"type":"print","value":"1050-0545"}],"subject":[],"published":{"date-parts":[[2017,7,1]]}}}
