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).
- HDA 280
- Hearing threshold
