Erratum: Correction to Table 3, in: Equivalent threshold sound pressure levels (ETSPL) for Sennheiser HDA 280 supra-aural audiometric earphones in the frequency range 125 Hz to 8000 Hz (International Journal of Audiology (2009) 48 (271-276))

Research output: Contribution to journalComment/debateResearchpeer-review


The main results in Poulsen & Oakley (2009) are given as the equivalent threshold sound pressure level, ETSPL, measured in an acoustic coupler specifi ed in IEC 60318-3. These results are all correct. The ETSPL values for the ear simulator specifi ed in IEC 60318-1 were calculated from acoustic laboratory measurements and unfortunately a simple sign error has been found that changes two of the columns in Table 3 of Poulsen & Oakley (2009).
