What Is Hearing Aid Compression and Expansion? - …
https://www.helpingmehear.com/hearing-aids-news/hearing-aid-compression-expansion/
Hearing aids that use WDRC make sounds louder at varying levels that depend on how loud the sounds initially were. The hearing aids can detect higher frequency sounds and then convert or compress them to lower frequency sounds that you are able to hear. While the nature or characteristics of the sound are modified, you are still able to hear what you were unable to …
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.

When using Real Ear Measurement to verify the correct amount of amplification & Compression for your hearing aids, Loud, Average, and Soft level Speech Sounds are presented from a loudspeaker in front of you. The amplification levels of your hearing aids are then measured inside of your ear canals with a Probe Microphone to determine if the correct amount of …

In many types of hearing aids, the wide intensity range of audi-tory is compressed into the relatively narrow dynamic range of the hearing aid recipient. Also, in cochlear prostheses, the wide dynamic range of our auditory environment must be compressed or "mapped" into the very narrow operating range of electrical stimulation of the nerve.

For example, a hearing aid might use a 3:1 compression ratio, meaning that the level of output goes up by 1 dB for every 3 dB increase in the level of the input signal. Most modern hearing aids use so-called wide dynamic range compression (WDRC), meaning that they compress a wide range of sound levels rather than just limiting loud sounds like the …

representation of the hearing aid output as a function of frequency. The input level and overall gain of the hearing aid are fixed when measuring a frequency response curve. Figure 1-9 depicts a sample frequency response curve of a hearing aid for an input of 60 dBSPL. It can be seen that the output of the hearing aid varies across frequencies.

The green curve shows the /s/ sound after processing with Digital Frequency Compression (DFC) by a factor of 3.5. Note that the two primary energy peaks of the "compressed" /s/ are above the thresholds and located at the more usable region, 1-2KHz. Wendy Davis has been an audiologist for 15 years. She practiced as a clinical audiologist and ...
