  • For peripheral measures, counts are given in terms of number of animals tested. For central auditory recording, counts are listed in terms of number of animals as well as the number units recorded from these animals. Percent values are listed as percent of total units recorded for each exposure type. All measure of dB listed are in dB SPL.
