Noise pollution is unwanted or excessive sound that can have detrimental effects on human health and well-being. It can come from a variety of sources, including traffic, construction, and industrial activities. The World Health Organization (WHO) has identified noise pollution as a major environmental health problem, and it is estimated that millions of people worldwide are exposed to harmful levels of noise.
There are a number of ways to avoid noise pollution, including:
Signal-to-noise ratio (SNR) is a measure of the strength of a signal relative to the strength of the background noise. It is used to assess the quality of a signal and to determine whether it is usable. A higher SNR indicates a better quality signal.
SNR is important in many applications, including telecommunications, audio processing, and image processing. In telecommunications, SNR is used to measure the quality of a voice or data signal. In audio processing, SNR is used to measure the quality of an audio recording. In image processing, SNR is used to measure the quality of an image.
