Title: Dancing the aerobics "Hearing loss choreography"
Issue Date: 2002
Abstract: This paper presents an overview of the health clubs acoustic problems when used for aerobics exercises classes (and similar) with loud noise levels in sound amplified music. A sample of five schools in Portugal was chosen for this survey. Noise levels in each room were measured and analyzed to calculate the standardized daily personal noise exposure levels (Leq8). Leq8 values up to 96 dB(A) were found in this type of room inducing a health risk for its occupants. This type of gymnasium is usually a highly reverberant space, which is consequence of a large room volume surrounded by hard surfaces. The reverberation time (RT) values were also measured and compared with some European legal requirements (Portugal, France, and Belgium) for nearly similar situations. RT values (1 kHz) from 0.9 s to 2.8 s were found and clearly differentiate between good and acoustically inadequate rooms. Some noise level and RT limits for this type of environment are given and suggestions for the improvement of the acoustical environment are shown. Significant reductions in RT values and noise levels can be obtained by simple measures as presented.
