Methods for the Measurement of Insertion Loss of Hearing Protection Devices in Continuous or Impulsive Noise Using Microphone-in-Real-Ear or Acoustic Test Fixture ProceduresMore info
This standard provides two methods for measuring the insertion loss of any hearing protection device (HPD) that encloses the ears, caps the ears, or occludes the earcanals. It contains information on instrumentation, calibration, electroacoustic requirements, subject selection and training, procedures for locating ear-mounted microphones and HPDs to measure sound pressure levels at the ear, specifications describing suitable ATFs, and methods for reporting the calculated insertion-loss values.
