Subject: [AUDITORY] DPM1 DPOAE microphone From: "Mertes, Ian Benjamin" <imertes@xxxxxxxx> Date: Thu, 17 Jul 2025 15:44:08 +0000--_000_MN2PR11MB42723AFA5D9B84BA50C824CFCA51AMN2PR11MB4272namp_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hello list, I currently use Etymotic Research ER-10B+ and ER-10C probes for measuring o= toacoustic emissions in humans. However, these probes are no longer sold or= serviced. I'm interested in the Tucker-Davis Technologies DPM1 DPOAE microphone<https= ://www.tdt.com/product/dpm1-microphone/> because it's battery powered and h= as a BNC connection. I would be interested in hearing about anyone's experi= ence with this probe.
