Subject: Re: [AUDITORY] Music specific hearing loss From: Frank Russo <russo@xxxxxxxx> Date: Fri, 20 Jul 2018 12:29:08 -0400 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--Apple-Mail=_F0F3FF9F-8BE0-46CE-9FA6-6975E624324C Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=utf-8 Dear Ross, I would echo comments already made by saying that music in hearing aids = can be problematic, and in the case of mild to moderate losses it can be = even worse than music without hearing aids, at least for some dimensions = of music (e.g., perception of timbre). In general the extra frills available in hearing aids like frequency = lowering and noise reduction tend to interfere with music perception. In = addition, the growing consensus is that less compression is more when = music is the input. There are certainly opportunities for improvements = in handling music but they require dedicated music programs. While most = manufacturers have these now, there is a wide disparity in outcomes. We developed the "adaptive music perception" (AMP) test in order to = assess perception of music by people with hearing loss. Our approach is = to assess individual dimensions using an adaptive threshold procedure. = We believe that this can serve as a useful complement to aesthetic = judgments of sound quality. The matlab code, documentation, and = validation pub are available here: https://smartlaboratory.org/resources/amp-test/ I know that some individuals have used the AMP test with an audiologist = in order to fine-tune their own hearing aids for music. There are 4 subtests and each takes about 10 minutes to complete.
