Subject: [AUDITORY] Music in Hearing Aids: Online Listening Test Participation From: "Webb, Jack" <j.webb24@xxxxxxxx> Date: Wed, 22 Oct 2025 10:21:27 +0000--_000_LO2P265MB25113D894A2D5F36D00E011CB1F3ALO2P265MB2511GBRP_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Dear all, We are looking for participants for the assessment of music quality in hear= ing aids. The goal of this study is to establish a database of variously pr= ocessed audio content rated by human listeners, with a view to developing m= ore informative models of music listening in hearing aids. The task involves a straightforward listening test, comparing sounds which = have been processed with a simulated hearing aid and hearing loss profile. = In each comparison, a pair of sounds is presented, and you will be asked to= select the sound that appears higher quality to you. The listening test is taken remotely on a personal computer, via a secure o= nline testing platform. It takes a minimum of about 15 minutes (for one blo= ck) and up to around an hour (for all four blocks, which is preferred but d= efinitely not required). The test can be taken in as many smaller batches a= s desired, without loss of progress between each session. If you are interested in taking part, please follow this link<https://pairw= ise-comp-09e420cdc6cd.herokuapp.com/>. Further information can be found in = the Participant Information Sheet<https://aws-listening-test-bucket.s3.eu-n= orth-1.amazonaws.com/20250818_InformationSheet.pdf>. You must be at least 1= 8 years of age to participate and have self-reported normal (i.e. unassiste= d) hearing. For any further questions, please feel free to get in touch via= email. Thank you in advance for your interest.
