| Abstract |
Contents of this international standard: scope and field of application; conformance; definitions; methods for determining sound power levels of equipment in reverberation rooms or under essentially free-field conditions over a reflecting plane; a method for measuring sound pressure levels at the operator and bystander positions. Annexes include a standard test table, alternative measurement surfaces for sound power measurements in accordance with the standard, installation and operating conditions for specific equipment categories and a measurement method of impulsive sound pressure levels and discrete tones at the operator position. |
