Perception of Recorded Music With Hearing Aids: Compression Differentially Affects Musical Scene Analysis and Musical Sound Quality.
Robin Hake, Michel Bürgel, Christophe Lesimple and 4 others
PMID 40853328WHAT IT FOUND
Slow compression hearing aids were preferred for music quality and speech clarity, but fast compression helped listeners separate instruments in complex music.
Only four participants preferred the same setting for all tasks, so no single compression mode fits everyone.
Key findings
01Slow compression settings produced the highest subjective sound quality ratings for music, outperforming fast compression and unaided listening.
02Fast compression settings resulted in better behavioral performance in separating instruments in complex musical mixtures compared to slow compression.
03Individual preferences for compression settings varied widely, with only four participants consistently benefiting from the same setting across all tasks.

What it does not show
Participants' prior familiarity with specific compression settings was not assessed, which may have influenced preferences. Testing was conducted at a single fixed playback level, so results may not generalize to varying loudness conditions. The study used recorded music stimuli, which may not fully replicate the experience of live music. Sound quality ratings may have been influenced by common method bias due to similar rating scales used for different attributes.
Declared interests
The study was funded by Sonova AG, which provided hearing aid prototypes, but the authors state that design, execution, and analysis were conducted independently.
The easy way to misread this
Do not assume that fast compression is universally better for music perception. While it aided the behavioral task of separating instruments, most participants preferred slow compression for overall sound quality, and individual benefits varied significantly across tasks.
