Sound Measuring Instruments as Applied to Noise Reduction

Measuring Sound and Noise

The European Community Green Paper on Future Noise Policy (1996) recognised that environmental noise is “one of the main local environmental problems in Europe” but that it has had a lower priority than other environmental problems, such as air or water pollution. It also recognised that, despite significant reductions in the noise produced by individual sources, total exposure to environmental...

Lung Sound Noise Reduction Using Gabor Time-Frequency Masking

The Gabor expansion is a mathematical tool, which provides a joint time-frequency representation of a given signal by decomposing it into time-frequency elementary signals called Gabor atoms. It has been used in a variety of signal processing applications, including biomedical signal processing. In this paper we present a time-frequency masking technique based on Gabor expansion for both heart ...
