GB/T 17312-1998
ActiveRandom-incidence and diffuse-field calibration of sound level meters
声级计的无规入射和扩散场校准
Application Summary AI generated
This standard specifies the procedures for calibrating sound level meters under random-incidence and diffuse-field conditions, ensuring accurate measurement of sound pressure levels in environments where sound arrives from multiple directions. It is applied in acoustics testing laboratories and industrial settings for calibrating instruments used in environmental noise monitoring, building acoustics, and product noise emission assessments. The standard is critical for compliance with noise regulations and for ensuring consistent measurement results across different testing scenarios.
