At my talk at 28c3, I played a couple of sound files to show my audience how I hear.
The original file is a song “Sad Robot” by “Pornophonique“.
This version has the high frequencies removed, which is typical for a hearing loss.
Additionally, I have a nasty tinnitus sound in the frequency range which is affected by my hearing loss. The following file has this sampled in. Since the tinnitus sound is similar to a feedback loop’s sound, you are advised not to play it too loud, because it could destroy audio equipment.
The tinnitus sound is taken from a website which provides a collection of typical tinnitus noises: http://www.ata.org/sounds-of-tinnitus
