RECD Measurement
Probe microphone
Figure 10.3 Measurement of RECD using a real ear
analyser, insert phones, and a probe microphone.
For ITEs, the insert phone is connected via foam
plugs to (a) a HA1 coupler, and (b) the patients
ear. For BTEs, the insert phone is connected to
(c) a HA2 coupler by 25 mm of tubing, and (d) the
patients ear by the individual earmold and
tubing. For both measurement types, a hearing
aid receiver in a BTE hearing aid case can be
used instead of the ER3A earphone if desired.
