Ordinarily, noise dosemeters had been reasonably substantial devices by using a microphone mounted close to the ear and using a cable going to the instrument physique, by itself commonly belt worn. These devices had a number of problems, predominantly the reliability on the cable as well as the disturbance towards the user's normal function mode, caused by the existence on the cable. In 1997 following a United kingdom analysis grant an EU patent was issued for the main of A selection of devices which were so tiny which they resembled a radiation badge and no cable was essential as the whole device may very well be equipped close to the ear.
