A noise dosimeter (x00) for monitoring the exposure to noise of a user wearing a headset is described. The noise dosimeter includes a housing to be worn external to the ear of the user, an earpiece (x01) for placement in or near an ear canal of the user, a microphone transducer, and a signal transmission means (x03) for transmission of a signal from the earpiece (x01) to the housing. The earpiece (x01) comprises sound collection means (x04) for collecting sound emitted from a speaker of the headset, and the housing 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. The noise dosimeter can be integrated in a headset.
