Digital hearing aids 'Useless for music'

Wearers of digital hearing aids struggle to listen to recorded music because of the way the devices process sound, research from the US suggests.

The researchers from the University of Colorado, Boulder found that the more sophisticated hearing aids boost softer sounds to aid speech recognition.

This process is called wide dynamic range compression.

However, it distorts recorded music, which tends to be compressed already during production.
The effect of both the recording compression and further compression by the hearing aid causes distortion.

Additionally, music - both recorded and live - is made up of many sounds at different volumes and changing these volumes changes the way the music sounds.

that's not good!!!
