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)
