What is the meaning of noise reduction?
Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree.
Is the most common method of noise reduction?
Therefore, full acoustical enclosures are generally the most common and effective noise control measure in the manufacturing environment. An acoustical enclosure functions by effectively containing the sound and then dissipating it by absorption.
