Abstract:

The efficacy of aqueous foam for reducing the noise level due to the breech blast of a shoulder-launched rocket weapon was investigated experimentally. Results indicated that, for canisters of practical size, modest reductions in peak sound pressure level SPL could be achieved, at the expense of significantly increased recoil impulse. Author
