Abstract:
1. A headset system for measuring the summation of sound in a user's ear during use of a headset, comprising: a headset having a housing including a speaker for transmitting sound from a remote communications source into a user's ear and sensor for measuring composite sounds reaching a user's ear canal, a microphone for receiving speech sound from the user of the headset, when the headset is worn by the user, wherein the sensor further includes a noise dosimeter and a sound signal input conductor from the dosimeter for simultaneously monitoring the composite exposure to noise of a user wearing the headset and all other sound sources entering the users ear canal, wherein the noise dosimeter is coupled to or an integral part of the headset and includes: a housing removable from said speaker to be worn external to the ear of the user, an earpiece insertable into the user's ear canal and including a ring sized to receive the noise dosimeter input conductor suspended within the ring for insertion directly in an ear canal of the user and said earpiece being generally porous to sound passing therethrough and including at least one passageway therethrough to permit the passage of sound through the ear canal, a microphone connected to said earpiece and suspended in said ring and connected to the dosimeter for simultaneously collecting a composite of ambient sounds and sounds coming from said speaker which reaches the ear canal, and a signal transmitter for transmission of a signal from the earpiece to the housing and wherein the earpiece comprises sound collector for collecting all sound entering the user's ear canal, and wherein the noise dosimeter comprises signal processing circuitry for processing and accumulating signals from the microphone transducer in order to evaluate a user's exposure to noise when using the headset.
