Sound propagation from a semi-open shooting range
conference paper
Semi-open shooting ranges, in contrast to a fully open shooting range, are often used in the densely populated area of the Netherlands. The Ministry of Defense operates a number of these ranges. In these shooting ranges above the line of fire a number of screens are situated for safety precautions to prevent bullets to exit the range. When a weapon is fired, the impulse sound from the muzzle blast reflects against the side-walls and screens and creates a complex sound field, which depends on the weapon/ammunition used and the firing position in the range. As a result the sound propagation from the semi-open shooting range strongly depends on the angle with respect to the line of fire. In order to predict the sound emission and to determine the effect of sound reduction measures, a numerical model is being developed. First results are shown and compared to recent measurements. The measurements were carried out for four different stages of the shooting range, with an increasing amount of absorption used on the side walls and screens.
