Abstract:

A new technique to measure power was used to gather one-third octave emissions data on the M1E1 engine AGT 1500 at the Stratford Army Engine Plant, CT and on the M1E1 power pack at Aberdeen Proving Ground, MD. To calculate sound power, acoustic intensity the product of the scaler pressure and the vector velocity was measured and integrated over an arbitrary surface enclosing the source. The data gathered and test results show this new technique is very powerful and robust and is applicable to many machinery quieting, source emission, or sound transmission measurements. Author
