Comparison of Acceptable Noise Level Generated Using Different Transducers and Response Modes

Table 1

The mean and standard error (SE) of MCL, BNL, and ANL obtained from the three repeated measurements in different methods. MCL: most comfortable listening level; BNL: background noise level; ANL: acceptable noise level; LS: measured through loudspeaker with self-adjusted levels using audiometer controls; LA: measured through loudspeaker with the subject signaling the audiologist to adjust the levels of speech and noise; ES: measured through earphones with self-adjusted levels using audiometer controls; EA: measured through earphones with the subject signaling the audiologist to adjust the levels of speech and noise.
