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 configured to be mounted within an ear canal of the person;
wherein the sound level recording means is configured to be external to the ear canal;
wherein the sound measurement means is configured to be shielded from noise from an external environment by an insert-type hearing protective device that is separate and apart from the sound measurement means;
wherein the cable is configured to not interfere with the ability of the insert-type hearing protective device to reduce the noise exposure level in the ear canal; and
wherein the sound measurement means is not mounted on the insert-type hearing protective device, but is configured to be mounted within the ear canal independently of the insert-type hearing protective device;
wherein the sound measurement means measures center-of-head noise exposure under both protected and unprotected conditions while located in only a single position within the ear canal of the person.

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.

12. 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 means is external to the ear canal;
wherein the sound measurement means is optionally shielded from the noise environment by an insert-type 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 the 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 (13, 14, 15, 16)

17. 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; wherein the sound measurement means is configured to be mounted within an ear canal of the person;
wherein the sound measurement means is configured to be optionally shielded from noise from an external environment by an insert-type hearing protective device that is separate and apart from the sound measurement means;
wherein the insert-type hearing protective device is operable to reduce the noise exposure level when in place in the ear canal;
wherein the sound level recording means is configured to be external to the ear canal;
wherein the means for linking the sound measurement means and the sound level recording means is operable to not substantially interfere with the ability of the hearing protective device to reduce the noise exposure level in the ear canal; and
wherein the sound measurement means is configured to measure noise exposure under both protected and unprotected conditions while located in only a single position within the ear canal of the person. - View Dependent Claims (18, 19)
