NOISE REDUCTION IN ACOUSTIC DISDROMETRY
8th European Conference on Noise Control 2009, 2023 This paper reports progress on the development of a novel rain disdrometer and the methods of noise reduction. The proposed instrument will measure the raindrop size distribution using the sound generated by raindrops landing in a tank of water. When an incident hydrometeor impacts on the surface of a liquid, two processes create an acoustic signal ...

Perceptual acoustic space of tire noise
INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2023 Road traffic noise accounts for the majority of perceived urban environmental noise and has important health consequences. The rolling noise of vehicle tires is a major contributor to perceived road noise. The tread pattern of light vehicle tires is already designed to minimize the amplitude of the noise emitted, but this is not the case for heavy ...
