Which statement best describes how a hearing aid works?

A microphone receives the sound, translates it to electronic signals, strengthens them, and sends them to the individual via the ear.

A microphone bypasses the interpretation of sound and instead relays the vibrations directly to the individual.

An implant bypasses parts of the cochlea and sends messages to the brain, where they are then recognized as sound.

An implant receives the sound and then softens it before translating into vibrations, which are then communicated to the individual.
