aids can also adjust different frequency ranges to compensate for any
tolerance problems and try to help overall speech clarity.
Modern hearing aids can also have multiple memories for storing
different prescriptions for different environments. Some have voice activity detection, which listens for speech

directional microphones which selectively focus on only those sounds
coming from directly in front of you or all directions.
Computer technology has dramatically improved the performance of
hearing aids.
