  • Patent number: 11978428
    Abstract: Systems for magnetoacoustically transferring sound across an acoustic barrier include first and second acoustic resonators positioned on opposite sides of the barrier. Each of the first and second resonators includes an attached magnet. Via magnetic coupling between the magnets, an acoustic oscillation at the first resonator induces an oscillation of the same frequency at the second resonator. Thus sound waves absorbed at the first resonator are magnetically transferred across the barrier to the second resonator, from which they are emitted.

  • Patent number: 11962977
    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.
