Abstract

The article contains a description of a new technique for assessment of the effectiveness of noise-protecting bushes and era-flaps against the intensive impulse noise of shooting a 105 mm cannon and heavy grenade cup discharges. The technique envisages a simultaneous measurement of the maximal noise pressure levels with a common microphone from the inside under the ear-flap. It was indicated that a simultaneous use of bushes and protecting ear-flaps was more effective, but still less than a summation effect of their individual noise-protecting properties.
