Objective: Identify the distribution of typical noise levels present in daily life and identify factors associated with average sound levels. Design: This was an observational study. Study sample: Participants (N=286) were 20 to 68 year old men and women, drawn from the general population of Kalamazoo County, Michigan. A total of 73,000 person-hours of noise monitoring were conducted. Results: Median overall daily average levels were 79 and 77 dBLeq A,8,equiv, with average levels exceeding EPA recommended levels for 70% of participants. Median levels were similar between the hours of 9 a.m. and 9 p.m., and varied little across days of the week. Gender, occupational classification, and history of occupational noise exposure were related to average noise levels, but age, educational attainment, and non-occupational noise exposures were not. Conclusions: A large portion of the general population is exposed to noise levels that could result in long-term adverse effects on hearing. Gender and occupation were most strongly related to exposure, though most participants in this study had occupations that are not conventionally considered noisy.
