摘要:

Recent subjective threshold calibrations of a range of audiometric earphones permit direct comparison of their equivalent threshold sound‐pressure levels on various artificial ears and couplers. Values of equivalent normal threshold sound‐pressure level, compatible with ISO Recommendation R389, are given for the TDH39 MX41‐AR earphones on an NBS type 9A coupler.
