The comparison of threes methods, spectral subtraction, LOGSTSA-MMSE and subspace approach, is the major work in researching the noise reduction algorithm.
在去噪算法上本文重点比较了谱相减法、LOGSTSA-MMSE与子空间方法。
According to the spectral characteristic of the noise source, the tube-type muffler, metal-enclosure muffler, structural-type muffler can be equipped before and after the noise reduction devices.
根据声源的频谱特性在其前后配置合理的管道式消声器、金属外壳式消声器、结构式消声器作为消声降噪的措施。
