UNCERTAINTY ANALYSIS OF NOISE EXPOSURE MEASUREMENTS FOR HEADPHONE USERS

摘要

Noise emissions from sources located close to the ear, such as the headphones of telemarketing operators are determined using the international standard ISO 11904. The MIRE and manikin techniques are applied simultaneously to estimate the levels of noise exposure. The uncertainties from different sources are estimated for the determination of the diffuse-field related equivalent continuous A-weighted SPL from an earphone.
