Abstract
A number of materials used for acoustic absorption have been tested to determine their relative effectiveness at high frequencies in attenuating weak shocks propagating in air. Weak shock waves of about 100 microseconds period and N-wave configuration were generated by flying 2400 feet-second rifle bullets over samples of material, and the details of the reflection of these waves at the surface of the materials were recorded by using shadowgraph-schlieren photographic techniques and pressure transducers.
