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. Int J Audiol, vol 48, 2009, pp. 271 − 276

Abstract

The main results in Poulsen & Oakley (2009) are given as the equivalent threshold sound pressure level, ETSPL, measured in an acoustic coupler specified in IEC 60318-3. These results are all correct. The ETSPL values for the ear simulator specified 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).

Key Words::

• Audiometry
• calibration
• HDA 280
• Hearing threshold
• ETSPL
