Different machines to meet all needs
Summary. Measurements of noise levels of 506 machine tools of 17 different types have been made by ICPMUA, Bucharest using the procedure laid down in BS 4813: 1972 and STAS 8857–82. The measurements were made in Roumania under workshop conditions, mainly with the machines running light at top speed.

In Germany, diamond grinding is frequently used to improve the evenness and skid resistance of concrete pavement surfaces. Since diamond grinding has been observed to affect tyre/pavement noise emission favourably, the relationship among surface texture, concrete composition and noise emission of concrete pavement surfaces has been systematically investigated.

The noise level of 100 mm Angle Grinders when 'free running' for example can vary from 95 to 100 dB(A). This is dependent on factors such as bearing condition, gearbox wear and the age of the tool. Some of the better manufacturers can supply noise level data on the performance of the tool.

Levels of noise generated from grinding machines were measured. Noise levels as high as 116dB was obtained. These levels of noise can be stressful that can result to fatigue. It is capable of causing temporary and permanent deaf. Noise spectra generated from grinding machines are mixture of low and high frequencies. Low and high frequencies noise can have negative effects on memory.

The speed of sound is about 1,500 meters per second in water and 5,000 meters per second in steel. The frequency, wavelength, and speed of a sound wave are related by the equation. c = f λ. Where c = speed of sound in meters or feet per second, f = frequency in Hz, and λ = wavelength in meters or feet.
