RECD Measurement ER 3 A (a) (b) HA 1 Real Ear Analyser Probe microphone

RECD Measurement ER 3 A (a) (b) HA 1 Real Ear Analyser Probe microphone (c) (d) HA 2 25 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 HA 1 coupler, and (b) the patient’s ear. For BTEs, the insert phone is connected to (c) a HA 2 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 ER 3 A earphone if desired. Source: Dillon (2001): Hearing Aids
