Thread-topic: [AUDITORY] Hearing Loss simulator for processing audio files

Hello Pragati,

you can try the 3D Tune-In Toolkit, which implements a non-linear attenuator (that can be calibrated from an audiogram), frequency smearing (Baer&Moore) and jitter. It also has a hearing aid simulator, and a binaural spatialiser.

Here is a video demonstrating the hearing loss functions

https://www.youtube.com/watch?v=jtEL__hwmq0

The Test Application (the one you see in the videos) is available for MacOS, Windows and Linux at the following link:

https://github.com/3DTune-In/3dti_AudioToolkit/releases/latest

At the link above, you can also download the VST plugin, both for MacOS and Windows, as well as the Unity wrapper

Best
Lorenzo

Subject: [AUDITORY] Hearing Loss simulator for processing audio files

Dear Colleagues,

I am looking for a hearing loss simulator that can simulate the impact of IHC and OHC loss when a given audiogram is fed and then process audio files with that information. This is so that a more nuanced impact of various degrees of hearing loss/shapes of audiogram on specific audio files can be shown instead of using band-pass filtering. If you know of any such tools or can recommend any articles/labs which have developed these, please let me know.

Thanks,

Pragati
