    Snippet: In other rooms, we measured noise and reverberation characteristics for less than an hour at each measurement position. At an operating room ( Fig. 2A) , background noise level, noise levels during three ear surgeries, and early decay time (EDT) were measured. The dimensions were 5.8 m×9.4 m× 3.5 m (H). At an examination room (Fig. 2B) , the background noise, noise during examinations, and the reverberation time (T20) were measured. The examina.....
    Document: In other rooms, we measured noise and reverberation characteristics for less than an hour at each measurement position. At an operating room ( Fig. 2A) , background noise level, noise levels during three ear surgeries, and early decay time (EDT) were measured. The dimensions were 5.8 m×9.4 m× 3.5 m (H). At an examination room (Fig. 2B) , the background noise, noise during examinations, and the reverberation time (T20) were measured. The examination rooms in the Otorhinolaryngology department were similar in dimensions of 3.5 m×4.0 m×3.0 m (H), in shape as rectangular, and in distribution of furniture and medical devices. There were three booths for audiometry and auditory brainstem response measurements, where the background noise and the reverberation time (T20) were measured. The dimensions were 2.3 m×2.0 m×2.0 m (H), 1.9 m×1.8 m×2.0 m (H), and 1.9 m×1.5 m×2.0 m (H), respectively.
