Study Notes
Types of Hearing Aids
- Analog hearing aids process sound by amplifying all sound equally, whether in quiet or noisy areas.
Digital Hearing Aids
- Sound waves in a digital hearing aid are converted into digital signals, processed, and then converted back into sound waves.
- Digital hearing aids provide better speech understanding when speech is present at an elevated level.
Hearing Aid Components
- The main function of a microphone in a hearing aid is to pick up sound waves.
- The processor/amplifier in a hearing aid processes the information picked up by the microphone and amplifies it.
Advanced Hearing Aids
- Digital hearing aids with directional microphones and noise reduction provide better performance in noise.
Analog Hearing Aids
- The main parts of an analog hearing aid are the microphone, amplifier, and speaker.
Tinnitus
- Tinnitus is a condition characterized by ringing or other sounds in the ears when no external sound is present.
- The primary causes of tinnitus are exposure to loud noise, earwax buildup, medications, and ear or sinus infections.
Cochlear Implants
- The main parts of a cochlear implant are the microphone, speech processor, transmitter, and electrode array.
