A Review on the High Sound Pressure Level Acoustic Measurement in the Aerospace Field

Noise could occur anywhere in the aerospace and other fields has a great influence on operation of aircraft. The control sound emission attracted lot attention from economic environmental aspects. Firstly, noise is annoying for passengers pilot may increase risk to be exposed military applications. Secondly, pose damage threat engine equipment due strong pressure oscillation. In addition, combustion also have process engine, which lead low-efficiency operation. measurement necessary very important research field. aircraft field usually works extreme environment, within high level, quite acoustic fields. Thus, we give short review introduce level
