| Abstract | Abstract : Pure-tone thresholds of 24 normal-hearing listeners were determined at 11 audiometric frequencies on two TDH-49 and two TDH-39 earphones. Thresholds were recorded in decibels of sound pressure level, as measured with a National Bureau of Standards type 9-A earphone coupler. Threshold data were used to compute appropriate calibration values for audiometers with TDH-49 earphones, reference Appendix F of ANSI S3.6-1969. |
