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.

A noise monitoring device for indicating exposure to noise and providing a quickly perceived noise exposure warning. Noise levels are monitored, recorded and evaluated by the device utilizing a noise detector, an accumulator, and an evaluator that monitors an accumulated noise signal value and determines a probability that continued exposure to the noise will exceed an acceptable value and issues a noise exposure warning if that probability exceeds a predetermined value. The noise exposure warning comprises a quickly perceived indicator such as a readily perceived visual symbol or tactile warning.

An apparatus is disclosed for managing the joint contribution of noise exposure of the ear of a user of the apparatus from a loudspeaker of the apparatus as well as from ambient noise so that the risk of risk of noise induced hearing losses is reduced. By assessing the joint actual sound energy delivered to the ear and feeding said assessment to a model describing the accumulated risk of hearing loss due to said sound energy accumulated over a time period, an estimate of the current risk of hearing loss is obtained. When said risk estimate passes a predetermined threshold, one or more protective measures are taken.

A Risk Assessment Company (RAC) maintains an up to date Risk Profile Data Base (RPDB) on its members based on their normal periodic updates to the RPDB. The Risk Assessment Company, therefore, can provide risk assessment results which can be utilized by a plurality of insurance carriers to determine an appropriate underwriting class for individual user subscribers who apply for insurance. The Risk Assessment Company can also provide a member with a risk assessment result report containing suggestions on how said person can better manage his or her risk exposure.

There is provided a method for determining a noise exposure level associated as the cause of an observed evolution of hearing acuity of an individual of known gender. The method comprises the following steps: 1) providing a first audiogram of the individual measured at age X and a second audiogram of the individual measured at age Y; 2) inputting the individual's gender, age X, and a time period equal to Y−X in a statistical hearing threshold levels evolution prediction formula; 3) calculating projected hearing loss audiograms specific to each of a plurality of possible noise level exposure values, using the prediction formula; 4) comparing a pattern of each calculated projected audiogram with a pattern the second audiogram; 5) selecting the projected audiogram that best fits the second audiogram; and 6) assuming that the noise exposure level value associated with the selected projected audiogram is the noise exposure value that caused the evolution of hearing acuity observed between the first and the second audiograms. There is also provided systems for performing the method and methods for providing services to clients or enabling users regarding determination of real ear noise exposure values.
