Measurement of airborne noise from hydraulic fluid power systems and components-Simplified method of determining sound power levels from pumps using an anechoic chamber
液压传动系统和部件的空气噪声测量
Describes simplified procedures for the determination of the sound power levels of a hydraulic fluid power pump under controlled conditions of installation and operation using a quadrispherical microphone array in an anechoic chamber. These procedures provide a basis for comparing noise levels of pumps.Cross References:BS 661BS 4196:Part 0BS 4196:Part 4BS 4231BS 5944:Part 1BS 5944:Part 2BS 5944:Part 3BS 5944:Part 4BS 5969BS 6413:Part 4ISO/DIS 3748
