This article brings a breakthrough in understanding the computation of direction of arrival (DOA) of sound waves and represents an important step in the further introduction of spatial domain into environmental noise and acoustics measurements in general. Instead of improving the accuracy of beamfor ...

Measuring the sound absorption coefficient in a small reverberation room below the Schroeder frequency is a challenging task and the results are subject to a high degree of uncertainty. Recent research shows that the low-frequency acoustic properties of the enclosure and the test sample should be ch ...

In this paper, an experimental approach for acoustic characterization of a household heat pump tumble dryer is developed. The main noise sources including BLDC motor, centrifugal fan, drain pump, and ventilation duct were identified using an acoustic camera survey based on beamforming, sound pressur ...
