Sennheiser HDA 200耳机和Etymotic Research ER-2插入式耳机的等效阈值声压级(ETSPLs)已经确定。31名听力正常的年轻受试者参加了测试，并确定了125赫兹至16千赫频率范围内所有推荐频率的阈值。HDA 200耳机的结果与目前可用的另外两项调查的结果基本一致。只有在6 kHz时才发现9分贝的偏差，而在8 kHz时，三次调查之间发现了6分贝的偏差。对于ER-2，在文献中找不到其他ETSPL测定方法。
Equivalent Threshold Sound Pressure Levels (ETSPLs) have been determined for the Sennheiser HDA 200 earphone and the Etymotic Research ER-2 insert earphone. Thirty-one young normal-hearing test subjects participated and the thresholds were determined for all recommended frequencies in the frequency range 125 Hz to 16 kHz. The results for the HDA 200 earphone are generally in very good agreement with the results from two other investigations 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 three investigations. For ER-2 it has not been possible to find other ETSPL determinations in the literature.
