--0000000000004d0c300636e531c2 Content-Type: text/plain; charset="UTF-8" Dear List We are doing binaural impedance measurements as part of a research project. For the hardware, we used the ER-10X (Etymotic, then bought by Interacoustics and discontinued). Sadly, one of the probes broke down and neither company appears to have spare probes left, so this beautiful device has become useless. We are looking for new hardware that would allow us to do simultaneous sound emission and recording in both ears. Does anybody have suggestions for hardware that we could use ? Or would anybody have the same problem, having a useless ER-10X with only one probe left ? thx for your input !
