Ergonomic standard
  • Abstract:
    This standard describes the determination of the noise emission of information technology and telecommunications equipment: - Determination of sound power levels in reverberation rooms (according to ISO 3741) and under essentially free-field conditions over a reflecting plane (according to ISO 3744 and ISO 3745); - Determination of emission sound pressure levels at the operator and bystander positions (according to ISO 11201). Test accessories, further measurement surfaces, installation and operating conditions for the specific equipment as well as procedures for identification of prominent discrete tones are described in annexes.
