Hearing Aid Features: Voice Activity Detection / Noise Reduction + Speech Enhancement
Voice activity detection, noise reduction and speech enhancement work together to deliver a clean, clear speech signal.
The human voice carries in very specific frequency and volume ranges. Distinct modulations of these frequency and volume ranges identify the speech signal in the hearing aid.
Once the speech signal is identified, the amount of amplification to all other signals is reduced while simultaneously increasing the amplification of the higher frequency ranges of the speech modulation.
