HEARING PROTECTOR UTILISING AURAL REFLEX MECHANISM

The effectiveness of electronic earmuffs is improved by incorporating a mechanism which causes the middle ear muscles to contract before an intense sound is generated. This contraction is achieved by incorporating a wireless receiver into the earmuff. Immediately prior to the generation of the intense sound, the wireless receiver receives a signal which causes it to generate a loud, non-damaging sound in a loudspeaker in the earmuff. The received signal is generated by a radio frequency transmitter that is activated immediately prior to the activation of the mechanism producing the intense sound. The non-damaging loud sound from the loudspeaker causes the middle ear muscles to contract (this is a natural reflex of the ear). The intense sound is received outside the earmuff before the reflex contraction of the middle ear muscles has been relaxed.
