Identification of the number and locations of acoustic sources

Journal of Sound and Vibration, 2005
The identification of the number and locations of acoustic sources is a fundamental problem of engineering acoustics. The method of multiple signal classification (MUSIC) has been widely used to solve this problem. The main drawback of the MUSIC method is that the unavoidable measurement noise should be identical for all the channels of measurement ...

Location of pointlike acoustic emission sources in anisotropic plates

The Journal of the Acoustical Society of America, 1989
In this paper is described a method by which a pointlike source of acoustic emission can be located in an anisotropic plate. The method is applicable for a source in an anisotropic solid of arbitrary symmetry as long as the principal acoustic axes of the material are known a priori.

Acoustic Emission Source Location in Anisotropic Composite Plates

1991
This work describes a method by which a pointlike source of acoustic emission can be located in a plate of composite material. The method is applicable to a source in an anisotropic material of arbitrary symmetry as long as the principal acoustic axes as well as the all set of elastic constants of the material are known a priori.
