Subject: Re: [AUDITORY] Hearing Loss simulator for processing audio files From: Alexander Brewer <afb8252@xxxxxxxx> Date: Sat, 8 Mar 2025 16:19:38 -0500--000000000000b4c807062fdb4c63 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable This question has gone around a few times, and 3D Audio Toolkit is usually the answer. I personally used the toolkit for great visual modification of signals in realtime to represent various types of hearing loss and hearing aid treatment. If you're looking for something more programmatic, you can check out Clarity's NALR and Audiogram modules here: https://github.com/claritychallenge/clarity/blob/main/clarity/enhancer/nalr= .py and here: https://github.com/claritychallenge/clarity/blob/main/clarity/utils/audiogr= am.py I used these modules in my own study, but they were a bit tricky to utilize out of the box. If you're looking for implementation details, feel free to take a look at my implementation here: https://github.com/hyve9/samplifi/blob/main/samplifi.py#L475-L499 You can import this in your own project with: from samplifi import apply_audiogram (See here for using as a module: https://github.com/hyve9/samplifi?tab=3Dreadme-ov-file#using-as-a-module) HTH!
