It helps to establish the relationship between coherent structures of sound field and locally coherent noise sources. In addition, the method can also be used to eliminate the influence of background noise by selecting POD modes with higher energy. WebThis tool calculates combined sound sources on the same distance Sound pressure levels are expressed in decibels which is a logarithmic scale. Therefore we cannot simply add sound levels.
