Multivariate modeling of factors associated with changes in individuals ’ noise exposure over time
We performed a further analysis to determine whether individual factors could explain an individual ’ s noise reduction experience over the first six months of use of the monitoring device. In a multivariate model, neither age, gender, HPD type, baseline hearing, nor baseline noise exposure level (average exposure level in first month of downloading) were significantly associated with the rate of decrease in noise over-exposures that individuals achieved.
