Abstract
Method and apparatus for locating and quantifying sound sources using an array of acoustic vector probes (). Signals received at the probes are converted to digital form and fed into a digital signal processor () which computes the sound pressure and the sound-intensity vector at each probe. The set of sound-intensity vectors measured by the array provides a set of directions to a sound source () whose approximate spatial coordinates are determined using a least-squares triangulation formula. The sound-intensity vectors also determine sound-power flow from the source. In addition sound pressure measured by the probes can be phased to form a sensitivity beam () for scanning a source. Sound-intensity measurements made concurrently can be used to determine the spatial coordinates of the part being scanned and the sound power radiated by that part. Results are displayed on a computer screen or other device () permitting an operator to interact with and control the apparatus. Additional related features and methods are disclosed.
