Abstract
A custom switchable hearing protection system includes an earplug and an electronic hearing device received in a recessed cavity in the earplug. The earplug includes a first portion disposed in a user's outer ear, a second portion disposed in the user's ear canal, and a sound tube extending through the second portion. The electronic hearing device includes electronics that incorporate digital signal processing to provide sound amplification and fast compression programming to shut off sound amplification to protect the user when a loud noise is detected. The housing of the electronic hearing device has a sound aperture for emitting the sound from a speaker assembly. The sound aperture is aligned with an opening of the sound tube, so that sound generated by the speaker assembly can propagate through the sound tube to the user's ear canal. A slider on the housing engages a switching device to activate or deactivate the electronics.
