Abstract
The NIMS software was designed to combine several metrics of noise and risk assessment into a single tool. The software provides a means to analyze the data off-line and facilitates calibration of .wav file recordings. Continued use of the NIMS software will undoubtedly revel new features of impulsive data that can enhance the ability estimate the potential damaging effects of high-amplitude noises. The NIMS tool has been used to analyze the small weapons impulses measured at an indoor firing range in Colorado using a mannequin to capture the signal underneath a hearing protection device. Ten weapons of various calibers were used to create impulses that were recorded both in free-field and underneath a protector (corresponding to the tympanic membrane location). The AHAAH model was use to estimate the auditory hazard units for each gunshot.
