Listening test

Harman how to listen

How to Listen is a desktop software application developed by the Harman International R&D group for the purpose of training and selecting listeners used in audio product research, development, and testing. The software consists of a number of training exercises where different kinds of timbral, spatial and dynamic distortions commonly found within the recording and audio chains are simulated and added to music.


This is a double blind A/B test, which is used to find the lowest distortion level where you can hear a difference between the reproduced sound and the original stimulus.



Philips Golden Ears training program was designed to develop the listening skills of audio engineers. It consist out of five key attributes: timbre, distortion, spatial impression, bass and loudness.

Audio ear training for recording musicians and sound engineers.

Get a daily sound workout, enhance your listening skills, and get better results in the studio.


A pretty good test to check for overall pitch perception ability.

The test is purposefully made very hard, so excellent musicians rarely score above 80% correct.
