Analysis of Operational Noise Measurements in Terms of Selected Human Response Noise Evaluation Measures

摘要

A comparison between common aircraft noise measures such as composite perceived noise level (PNLC), maximum perceived noise level (PNLM), A-weighted level, D-weighted level and noise exposure level (NEL), and the corresponding effective perceived noise level (EPNL) was made. Differences between EPNL and each of these measures were computed for the 727, KC-135, 707-320B, and DC-9 aircraft for three take-off and four approach operational procedures. (Author)
