5 NOISE SOURCES - WHO
www.who.intThis means that some new noise problems are closely related to the use of modern technologies. 5.2.1. Mechanical Noise A solid vibrating surface, driven or in contact with a prime mover or linkage, radiates sound power (W in Watts) proportional to the vibrating area S and the mean square vibrating velocity
5. Noise Management - WHO
www.who.intaddition to noise level limits for new vehicles (type test), noise emissions of vehicles already in use should be controlled regularly. Limits on the sound pressure levels for vehicles reduce the noise emission from the engines. However, the main noise from traffic on highways is rolling noise. This may be reduced by

Quantization Noise
classes.engineering.wustl.edu• To measure the Quantization noise, we should replace the 17 signal bins with the value of the leftmost signal bin (92) to approximate the quantization noise in the signal bins. The integral of this modified PSD from 0 to F s/2 is the noise power, σ2. The square root of this integral is …
