Abstract

A target has an acoustic chamber (4) within which microphones (5) are arranged to receive the soundwaves generated by a fired projectile entering said chamber. The microphones (5) are connected to means adapted to establish the hit position of the projectile on the basis of differences in the transit time of the soundwaves to the microphones (5). The acoustic chamber (4) is defined forwardly by a sounddelaying wall (12) having a thickness such that the soundwaves generated by the projectile and passing through the wall will reach each optional point on the inner side of said wall, and thus each microphone (5), later than the soundwaves generated by the projectile as it enters the chamber (4), and this also when the said point is located in a hole previously punched into the wall (12).
