| Abstract: | Aviation noise effects the communication and health of aircraft crew and ground crew seriously, elimination of noise is an effectively method to solve this problem. A new modified spectral subtraction was purposed. According to collecting real data of aviation noise, comparing the outcomes of classical spectral subtraction and modified algorithm, the result showed the modified algorithm could eliminate aviation noise effectively and improve the intelligibility and SNR of speech signal. |
