Abstract
Equivalent Threshold Sound Pressure Levels (ETSPLs) have been
determined for the Sennheiser HDA 200 earphone and the Etymotic
Research ER-2insert earphone. Thirty-one young normal-hearing test
subjects participated and the thresholds were determined for all
recommended frequencies in thefrequency range 125 Hz to 16 kHz.
The results for the HDA 200 earphone are generally in very good
agreement with the results from two otherinvestigations which are
available at present. Only at 6 kHz is a 9 dB deviation found and
at 8 kHz a 6 dB deviation is found between the
threeinvestigations. For ER-2 it has not been possible to find
other ETSPL determinations in the literature.
