Hearing threshold determinations have been performed with EARTONE 3A insert earphones and compared with threshold measurements performed with TDH 39 supra-aural earphones. 22 normal hearing subjects participated. Results are given as SPL values measured in an acoustic coupler (IEC 126) and an occluded-ear simulator (IEC 711).
使用EARTONE 3A插入式耳机进行了听力阈值测定,并与使用TDH 39头戴式耳机进行的阈值测量结果进行了比较。22名听力正常的受试者参与其中。结果以在声耦合器(IEC 126)和闭耳塞模拟器(IEC 711)中测量的声压级(SPL)值给出。
