Popis: Reference‐threshold levels for the new Telex 1470 audiometric earphone were determined at ten frequencies. The psychophysical method of adjustment was employed, utilizing a transfer standard technique. Based on the judgments of 12 subjects, mean reference‐threshold sound‐pressure levels in the NBS 9‐A type coupler were found for the Telex 1470 earphone.
