Hearing Conservation and Impulse Noise in the British Army

Army service has always presented a risk to hearing from impulse noise in addition to noise from small arms, with a typical peak pressure of 160 dB at the user’s ear; a number of weapon systems in current service give peak pressures up to 185 dB (35 kPa) in crew positions. To an increasing extent, soldiers are also exposed to continuous noise in vehicles or in workshops; these levels can exceed 100 dBA at the ear, even where hearing protection is used. The problem is becoming more acute, since the quest for more power from equipment of reduced size and weight tends to increase noise at the user’s position. At the same time, interest in hearing conservation measures is increasing, not only because of the greater risk of hearing loss, but also because awareness of the effects of noise is increasing as the use of monitoring audiometry becomes more widespread. It is therefore becoming vital to be able to predict the risk of hearing loss and the resulting disability from measurements (or, in the case of equipment still at the design stage, from predictions) of the noise exposure.
