Abstract (en)
[origin: EP1931172A1] The device has a microphone (MI) recording an interference sound outside the ear, and a receiver (H) outputting a processed electrical or electromagnetic useful signal. A sound transmission function (H-vent) is vent from the microphone to the eardrum (TF). The transmission function (H-anc) of a filter (F) is formed as a function of the sound function such that the interference sound reaching the eardrum through the vent is reduced in the effect on the eardrum by a balancing sound which is generated on the basis of an interference sound signal of the microphone from the receiver. An independent claim is also included for a method for reducing an interference sound when wearing a hearing device.
