    • A hearing instrument in accordance with the invention comprises an in-the-ear-canal component to be worn at least partially in the ear of a user. When the hearing instrument is worn, a remaining volume between the in-the-ear-canal component and the user's eardrum is defined. The hearing instrument includes at least one first microphone operable to convert an acoustic input signal incident on the hearing instrument into an electrical input signal, signal processing means operable to convert the electrical input signal into an electrical output signal on a signal path, and an electrical-to-acoustic converter (a receiver or a plurality of receivers with potentially different frequency characteristics). Between the remaining volume and surrounding atmosphere, a duct (such as a vent) is defined. A second receiver is in operative communication with the duct, i.e. an output directly opens out into the duct or to a sound conductor opening out into the duct. The hearing instrument further comprises a second microphone in operative communication with said duct and operable to record an error signal in said duct.
    • 根据本发明的听力器械包括至少部分地佩戴在使用者的耳朵中的耳内通道部件。 当听力仪器佩戴时,定义耳道内部件与使用者耳膜之间的剩余体积。 听力仪器包括至少一个第一麦克风,其可操作以将入射在听力仪器上的声学输入信号转换为电输入信号,信号处理装置可操作以将电输入信号转换为信号路径上的电输出信号,以及电气 声转换器(具有潜在不同频率特性的接收机或多个接收机)。 在剩余体积和周围大气之间,定义管道(如排气口)。 第二接收器与管道操作地通信,即,输出件直接通向管道或通向导管内的声音导体。 听力仪器还包括与所述管道可操作地通信的第二麦克风,并且可操作以在所述导管中记录误差信号。
