(b) (a) ER3A HA1 Real Ear Analyser Probe microphone (d) (c) HA2 25 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 patient’s ear. For BTEs, the insert phone is connected to (c) a HA2 coupler by 25 mm of tubing, and (d) the patient’s 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. Source: Dillon (2001): Hearing Aids
