Prediction System Design on Noise Airworthiness Compliance
Guo Hua Yan, Shi Qi Liu, Wen Qian Song · Advanced materials research · 2014
According to the method described in Technical Manual of Aircraft Noise Evaluation Procedures, this system can predict the EPNL (Effective Perceived Noise Level) of aircraft take-off, approaching and side boundary. The system also contains the function of managing andcalling NPD database, and can assess the predictive value basing on the noise stringency curve. This saves a number of cost for the airworthiness certification of aircraft noise, and is a new engineering practice which has a good application value.
