ScanPaint, a new fast tool for sound source localization and quantification of machinery in reverberant conditions

摘要

Sound source localization methods are widely used to reduce the sound emission of machinery. These methods are based on sound pressure measurements and often require an anechoic environment to be applied. The Microflown sensor can measure particle velocity directly which is less affected by background noise and reflections. This property of the sensor is now used together with a new approach termed Scan&Paint for fast stationary sound source localization.
