Probe Tube Microphone. Probe tubes are attached to microphone cases in order to distance the device from the sound field being measured When fitting hearing aids the tube is inserted into the ear canal with the microphone worn on the outside of the ear.

The effects of loudspeaker azimuth and reference microphone location on probe tube microphone measures were assessed The real ear unaided response (REUR) real ear aided response (REAR) and real ear insertion response (REIR) were obtained on a KEMAR Aided measures were obtained with both a behindtheear and an intheear hearing aid Author M A Ickes D B Hawkins W A CooperCited by Publish Year 1991.
Probe Microphone Placement for Real Ear Measurement: Update
This is a timedependent model of a generic probe tube microphone setup consisting of an external acoustic domain an elastic probe tube and the cavity in front of the microphone diaphragm The probe tube modeled using the Pipe Acoustics Transient physics interface is connected to two separate 3D pressure acoustics domains leading to a fully coupled acoustics simulation.
Effect of reference microphone location and loudspeaker
The GRAS 40SA Probe Microphone is a small compact unit for soundpressure measurements in small enclosures in harsh environments and in very close proximity to sound sources The high acoustic input impedance at the tip of the probe minimizes its influence on the acoustic field while the stainlesssteel tube of the probe can withstand temperatures of up to 800 ºC.
