Having one ear occluded can improve BC thresholds, which will give a false result. Once unmasked bone conduction thresholds have been obtained, then the surpa-aural headphone or insert earphone should be placed on the non-test ear (NTE) for masking purposes. Masking protocols will not be discussed here in detail.

Employers who want to use insert earphones must enter the 7 dB shift information in the employee's audiometric test records although it is not an "STS". When the next annual audiogram using insert earphones shows an average threshold shift at 2000, 3000 and 4000 Hz of 3 dB, completing the full shift (7 dB + 3 dB), employers must then label that average shift as …

Six Reasons to Use Insert Earphones. 1. Improved noise reduction. Foam insert ear tips seal the external auditory canal and block out ambient noise. Insert earphones (IE) can reduce 30 dB or more of noise. This ensures testing down to the lowest thresholds, and that ambient noise does not distract the patient.

testing completed using insert (EAR 3A) phones w/ good inter-test consistency (c) Initial unmasked, unoccluded BC thresholds suggested HLs significantly better (10-20+ dB) than AC thresholds that were recorded especially from 500 Hz – 1KHz. (d) Masking applied, and sometimes BC thresholds would shift to within 5-10 dB of AC
