摘要：
The invention regards a hearing device with two or more microphone units each having a conduit leading from a respective sound inlet in the hearing-device housing to a respective transducer, wherein the lengths of the conduits may differ without causing a difference in the frequency characteristics of the microphone units and wherein ultrasonic frequencies may be dampened, while at the same time providing higher freedom in the physical layout of the hearing device. This is achieved in that each conduit comprises a chamber and a pipe forming a resonator, and in that the frequencies of resonance (f1, f2) of the resonators are equal.
