The project is about people’s view and need of hearables and Peggy gave me the opportunity to express my opinion here. I enjoyed the conversation very much, I hope you do too. Here’s the video (in German):

Hearing Aid World meets Open Source

To my delight, I found out that my 28c3 talk was recently linked from an article on (which is the German slashdot).

I love to see that by now there are projects pursuing what I was calling for in my talk. That hearing aid hardware and software development becomes more open and accessible to every geek out there.

Btw. In case you are wondering: while I share the first name with the author of this article, it’s not me 🙂

Slides and speaker notes of my talk “Bionic Ears” at 28c3

As promised, I provide the slides of my talk “Bionic Ears” at the 28c3 hacker conference in Berlin.

28c3 “Bionic Ears” Slides

I also offer a version with detailed speaker notes, because especially my hearing-impaired audience might need it to be able to follow. I had to downsample the images in this version to avoid the files getting too big. Please have a look at the “slides only” version for details in the images.

Sound of my Hearing Loss

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:
