ADAPTIVE FREQUENCY RESPONSE, ADAPTIVE AUTOMATIC LEVEL CONTROL AND HANDLING RADIO COMMUNICATIONS FOR A HEARING PROTECTOR

摘要

An hearing protection device is provided. The hearing protection device can include a speaker to relay sounds, such as conversations, to the user of the hearing protection. The hearing protection device can include an electronics package that can filter out undesirable sounds, such as to improve the user's ability to hear conversations around them while still protecting the user's ears.

主权项

1. An apparatus for hearing protection, comprising:
a microphone disposed on the apparatus, the microphone configured to pick up an input sound wave from the environment and convert the input sound wave to an incoming signal; a processor, configured to apply a band pass filter to the incoming signal to create an output signal; a speaker disposed on the apparatus, the speaker configured to produce the output from the processor; wherein the band pass filter is selected from a plurality of band pass filters, wherein selection of the band pass filter is based on an average amplitude of the incoming sound wave; wherein at least one of the band pass filters for larger amplitudes is more narrowly focused on a selected range of frequencies than at least one of the band pass filters for smaller amplitudes.
