项目摘要
Noise measurements made for the purpose of hearing conservation practice
have as their objective the extraction of some physical metric from the
noise that can be used to estimate the hazards to hearing from prolonged
exposure. Current practice continues to rely primarily upon a time
averaged, integrated approach to quantifying a noise (i.e., an energy
metric) despite substantial evidence of the inadequacy of this measure in
a variety of industrial situations. Recent experiments have shown that
conventional measures of noise exposure such as Leq (equivalent level) and
spectrum were poorly correlated with trauma, but that metrics that
quantify the temporal characteristics of the noise such as frequency
domain kurtosis were highly correlated with both the frequency specificity
of hearing loss and the severity of trauma. The primary objective of the
proposed research is to develop analytical methods based upon contemporary
signal analysis technology that can be used to better characterize noise
exposure for the purpose of hearing conservation. The wavelet
transformation and the bicepstrum will be developed to obtain metrics
which will quantify the temporal characteristics of an exposure and which
when used in conjunction with conventional measures will more accurately
assess the potential of that noise for producing hearing loss.
Specifically, the distribution of time domain kurtosis, the joint peak-
interval histogram and the frequency domain kurtosis will be the primary
metrics that will be obtained from these analytical techniques.
