A Comparsion of Acoustic and Psychoacoustic Measurements of Pass-Through Hearing Protection Devices

In environments where listeners need to detect low-level sounds while being protected from high-level noises, electronic pass-through hearing protectors (EPHPs) offer an appealing alternative to traditional passive earplugs or earmuffs. In this paper, we compare acoustic measurements of the Head-Related Transfer Functions associated with eight different EPHPs to localization results measured on human listeners with the same devices. The results are discussed in terms of the insights they can provide for the design of improved EPHP systems.
