What term refers to small electronic devices worn in or behind the ear to amplify sound?

• A. Hearing aids
• B. Headphones
• C. Ear plugs
• D. Cochlear implants

Answer: (A)

The term refers to small electronic devices worn in or behind the ear to amplify sound for someone with hearing loss. Hearing aids pick up ambient sounds with a microphone, boost the signal with an amplifier, and deliver clearer sound to the ear through a speaker, helping you hear more easily in everyday environments. They’re designed specifically to improve audibility, and modern models come in behind-the-ear or in-the-ear styles with features like directionality and noise reduction. This is different from headphones, which simply deliver audio from a device; ear plugs, which block or reduce noise; and cochlear implants, which are surgically implanted and bypass damaged parts of the inner ear to stimulate the auditory nerve, not just amplify sound like typical hearing aids.
