Hearing Threshold Tester for PC

How good are your ears?

Hearing Threshold Tester for PC
The hardware and software presented here is meant to be used to easily test your hearing. It is possible to determine your hearing threshold and you can perform an A-B-X test to see what differences there are in sound quality between, for example, an MP3 file and a WAV file. With future enhancements of the software (which you could easily write yourself) you can carry out a number of other tests and gain a better understanding how your ears work and what you can and cannot hear.

Gerber file

CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor Members can exclusively download these files for free as part of their Membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service. Elektor recommends its business partner Eurocircuits as the company of choice for its own prototypes and volume production in selected cases.

Download the BOM list
The BOM (Bill of Materials) is the technically exhaustive listing of parts and other hardware items used to produce the working and tested prototype of any Elektor Labs project. The BOM file contains deeper information than the Component List published for the same project in Elektor Magazine. If required the BOM gets updated directly by our lab engineers. As a reader, you can download the list here.
