Abstract:
An apparatus for hearing protection comprises a pair of earpads, a band, microphones, speakers, vibration generators, and a processing unit. Each of the earpads is placed over an ear of the user. The band extends between the pair of earpads. The microphones convert acoustic signals into electrical signals. The speakers are located on each of the pair of earpads and direct sound towards the ear. The vibration generators are located on at least one of the pair of earpads and generate vibratory feedback to the user. The processing unit is connected to the microphones, the speakers, and the vibration generators, and compares first parameters of the electrical signals from the microphones with second parameters of predetermined warning sounds to determine whether the electrical signals comprise one or more of the predetermined warning sounds. If the processing unit determines that the electrical signals comprise one or more of the predetermined warning sounds, the processing unit transmits a warning to the speakers and the vibration generators.
