The ambient noise levels of 33 rooms, in 10 different nursing-home facilities, were measured to determine if the levels were in compliance with ANSI S 3.1 1991 maximum allowable ambient noise levels for audiometric testing. Results revealed that none of the rooms were in compliance with the standard for assessment of hearing thresholds at 0 dB HL. However, if the assessment levels were raised to 20 dB HL (or 35 dB HL), then 8 (or 29) of the 33 rooms would be in compliance. In addition, the utilization of insert earphones combined with raising the reference hearing threshold level to 10 dB would result in an environment in which accurate hearing thresholds may be measured down to 10 dB HL in all 33 of the sampled rooms.
