Abstract The accuracy of audiometric testing is fundamentally reliant on controlling ambient noise to prevent the masking of test stimuli. Various audiometric transducers, including supra-aural, circumaural, and insert earphones, as well as integrated headset systems, offer differing levels of passive sound attenuation.
