Auditory Signal Processing: Mechanisms of Modern Hearing Aids
Hearing aids are sophisticated electroacoustic devices designed to amplify and modulate sound for individuals with hearing impairment. Modern digital aids do more than increase volume; they use complex algorithms to improve speech intelligibility in noisy environments.
The Digital Pipeline
Microphone: Captures acoustic waves and converts them into digital signals.
Processor: Filters out background noise and enhances specific frequencies based on the user’s audiogram.
Receiver (Speaker): Converts the processed signal back into sound waves and delivers them into the ear canal.
