大多数情况下,我们可以将波动小于3 dB(A)的噪声称为 稳态噪声(steady noise),如常见的车床削工件、水泵机组运转等噪声,反之噪声被称为非稳态噪声(nonsteady noise);从时间看,如果噪声持续时间短于0.5 秒,间隔时间大于1秒,且声压有效值变化大于40 dB 时,可以将其统称为脉冲噪声(impulse noise),冲床冲压工件时发出...
In order to reduce noise pollution, we should begin by creating stricter laws that limit construction noise. Construction should not be permitted in early mornings, and should not go beyond acceptable noise levels. The city should also establ...
Noise Level: dB tracker is a powerful application which will allow you to measure noise with your phone microphone. It shows real-time noise value in decibels (…
The proper amount of noise reduction depends upon the type of background noise and the acceptable loss in quality for the remaining signal. In general, you can increase the signal‑to‑noise ratio by 5 to 20 dB and retain high audio quality. To achieve the best results with the Noise ...
