EZIL Hearing Protector Attenuation Application


EZIL is a data acquisition application to conduct insertion loss testing on hearing protectors in accordance with industry standards*. By automating the Trident multi-function acoustic analyzer EZIL acquires 1/3 octave data for reference, unoccluded, and occluded sound pressure levels to calculate the attenuation of the hearing protector. Test results are plotted in real-time and can be exported into Microsoft Excel templates for post-process data analysis.
