Abstract |
Fluid-flow machines, such as compressors, power station equipment, industrial fans, and Diesel ship engines may emit infrasonic noise in which the maximum energy falls within the range of infrasonic frequencies from 2 to 16Hz and low acoustic frequencies. Sources of this noise are indicated and measures for its reduction given, e.g. application of mufflers in intake systems of piston compressors, redesigning and application of mufflers of special design in machines and other devices used in thermal and hydraulic power stations, reduction of low frequency vibrations of Diesel ship engines and their parts. |
