ABSTRACT:
A method for continuously monitoring noise exposure level of a person via measuring sound level within an ear canal of the person using a sound measurement means linked to a sound level recording device external to the ear canal, wherein the sound measurement means may be shielded from the environment by a hearing protective device, and wherein the cable does not interfere with the ability of the hearing protective device to reduce noise exposure level in the ear canal. Also provided are a system comprising a sound measurement means mounted within an ear canal of the person, an external sound level recording means and a linking cable. Further provided is a system for providing continuous noise exposure monitoring level of a person, and for providing radio communication in a noisy environment, said system comprising the above sound monitoring system linked to a radio signal transmission means, and is switchable between said sound level recording means in a recording mode and said radio signal transmission means in a communication mode.
