Situational Hearing Enhancement and Protection

摘要

System and methods can provide both hearing enhancement and hearing protection. An audiogram can be determined for either an individual person or a group of people. A frequency spectrum of an environment can be determined for an environment within which hearing enhancement and/or hearing protection is needed. The audiogram and the frequency spectrum of the environment can be used to modify an electronic signal to attenuate noise and to amplify information. The information can be voice, sirens, bells, or anything else that the user desires to hear.
