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.
