DS DSEN SO 6926 2001-OCT-03 Acoustcs - Requrements for the performance and calbraton of reference sound sources used for the determnaton of sound power levels
This standard specifies the acoustical performance requirements for reference sound sources with regard to: 1) temporal steadiness and repeatability of the sound power output; 2) spectral characteristics; and 3) directivity index. It also specifies procedures for calibrating a sound source intended for use as reference sound source for the determination of sound power levels.
