| Abstract: | S The threshold level equipmentS of the background noise are different for the anechoic rooms of different applications. This paper illustrates how to determine such background noise threshold level during the design of anehoic rooms for electric-acoustic measurement, for A-Weight sound power level machine noise measurement, and the hearing measurement room for medical use. |
