Description:Improving the Assessment of Noise Exposure and Warning Signal Audibility on Construction Sites. Nikolina Samardzic, Aslihan Karatas, Behzad Esmaeili. CPWR Small Study, 2023.
"Fifty-one percent of construction workers are
exposed to hazardous noise that can cause
permanent noise-induced hearing loss, and 52%
do not wear a hearing protection device. Hearing
loss could be reduced more effectively with
more accurate measurements of noise exposure,
but common occupational noise exposure
measurement devices are single-channel noise
dosimeters worn on a worker’s shoulder that are
not advanced enough to capture and analyze
complex sounds that threaten workers’ hearing.
This project examined a more accurate noise exposure and warning signal audibility assessment by using binaural (two-ear) measurements, which are similar to human hearing. Developing this measurement would pave the way for more effective noise characterization and hearing loss prevention, as well as helping workers better identify audio warnings. The researchers obtained binaural measurements with volunteer workers on a mixed-use development construction site and conducted an acoustic perception study in a laboratory with human participants.
