Methods and Apparatus for Continuous Noise Exposure Monitoring
First Claim
1. A system for continuously monitoring noise exposure level of a person, said system comprising:
- a sound measurement means for measuring sound level, a sound level recording means, and a cable linking the sound measurement means and the sound level recording means;
wherein the sound measurement means is mounted within an ear canal of the person;
wherein the sound level recording device is external to the ear canal;
wherein the sound measurement means is operable to be shielded from the environment by a hearing protective device that is separate and distinct from the sound measurement means; and
wherein the cable does not interfere with the ability of the hearing protective device to reduce noise exposure level in the ear canal.

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 is 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.

13. A system for continuously monitoring noise exposure level of a person, said system comprising:
-
a sound measurement means for measuring sound level, a sound level recording means, and a means for linking the sound measurement means and the sound level recording means so that sound level measurements are transmitted to the sound level recording means; wherein the sound measurement means is mounted within an ear canal of the person;
wherein the sound level recording device is external to the ear canal;
wherein the sound measurement means is optionally shielded from the environment by a hearing protective device that is separate and distinct from the sound measurement means;
wherein the means for linking the sound measurement means and the sound level recording means does not interfere with the ability of the hearing protective device to reduce noise exposure level in the ear canal; and
wherein the sound measurement means measures exposure under both protected and unprotected conditions while located in only a single position. - View Dependent Claims (14, 15, 16, 17)
