The Compression Handbook - StarkeyPro
https://starkeypro.com/pdfs/The_Compression_Handbook.pdf
Compression amplification is a means for fitting the world of sound (the elephant) into the narrow dynamic range of the individual with hearing impairment (suitcase). This handbook is designed to provide the reader with a working knowledge of compression amplification: what it is, how it works, and how it is applied.
Hearing Aid Compression: Effects of Speed, Ratio and ...

Fast-acting compression should ideally only be applied with very low compression ratios in hearing aids with narrow frequency channel bandwidths. Although short regulation times may provide more audibility at soft input levels, the results reported here indicate that the audibility achieved will come at a considerable cost in terms of degraded sound quality.
What Is Frequency Compression in Hearing Aids?
https://www.hearingtracker.com/resources/what-is-frequency-compression-in-hearing-aids
Frequency compression is the process of shifting sound from one pitch to another to make speech sounds more audible. Most age-related hearing loss occurs in the high-pitches, which is why women’s voices are harder to hear for those with a typical age-related hearing loss. Amplification of high-pitch speech sounds is the typical remedy, but due to the progressive …

Hearing Aid Features Explained | Compression
https://drcliffaud.com/videos/compression-hearing-aid-feature
The reason compression is so important is that someone with a hearing loss has a more narrow range of sounds that are audible, and all of the same sounds that the normal hearing person can hear must be "compressed" into that narrow range. In order to make this happen, compression must be utilized when programming hearing aids.
Theoretical and Practical Considerations in Compression ...
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4172289/
Very simply, compression is the process whereby the intensity relationship among various segments of the acoustic stimuli is altered over time. The result is that the range of SPL variation in the long-term output is reduced relative to the range at the input. In the short term, however, such intensity relationship is maintained.

Wide-dynamic-range compression, or WDRC, technology is able to improve the hearing of people who have a severe form of hearing loss. Instead of merely making sounds louder, hearing aid compression works by manipulating sound. It allows people who wear hearing aids to hear sounds that they were unaware that they were not hearing.

The compression function relates the loudness of the input to the loudness of the output. The amount of gain applied by DRC algorithm is determined by a compression curve. The flatter the curve, the more the dynamic range of the sound is reduced.
