摘要： A hearing aid comprises an input transducer (2) for transforming an acoustic input into an electrical input signal, a subtraction node for subtracting a feedback cancellation signal from the electrical input signal thereby generating a processor input signal, a signal processor (3) for deriving a processor output signal from the processor input signal, an output transducer (4) for deriving an acoustic output from the processor output signal, a pair of equalization filters (7a, 7b) comprising a frequency selection unit (10i, 10j, ..., 10n) for respectively selecting from the processor input and output signals a plurality of frequency band signals, a frequency equalization unit (14i, 14j, ..., 14n) for frequency equalization for the selected frequency band signals, and an adaptive feedback estimation filter (5, 6) for adaptively deriving the feedback cancellation signal from the equalized frequency band signals. The equalization of selected frequency bands of the input signals of the adaptive feedback cancellation filter provides for an improved and in particular a faster adaption of the feedback cancellation while at the same time ignoring frequency ranges not relevant for the feedback cancellation process.

摘要： A hearing aid comprises two microphones, directional processing means (Dir1, Dir2) for combining the respective audio signals to form a spatial signal, a beamformer (35) for controlling the directional processing means to provide adaptation of the spatial signal, and means (LFB1, LFB2) for boosting low frequencies of the spatial signal. A feedback estimator generates a feedback compensation signal (7a, 7b), which is combined with the boosted spatial signal. By applying feedback compensation only after directional processing and low frequency boosting, the device avoids interference by the feedback estimator with the function of the beamformer. The invention also provides a method of processing signals in a hearing aid.

摘要： A hearing aid comprising a frequency shifter (20) has means (22) for detecting a first frequency and a second frequency in an input signal. The frequency shifter (20) transposes a first frequency range of the input signal to a second frequency range of the input signal based on the presence of a fixed relationship between the first and the second detected frequency. The means (34, 35, 36) for detecting the fixed relationship between the first and the second frequency is used for controlling the frequency transposer (20). A speech detector (26) configured for detecting the presence of voiced and unvoiced speech is provided for suppressing the transposition of voiced-speech signals in order to preserve the speech formants. The purpose of transposing frequency bands in this way in a hearing aid is to render inaudible frequencies audible to a user of the hearing aid while maintaining the original envelope, harmonic coherence and speech intelligibility of the signal. The invention further provides a method for shifting a frequency range of an input signal in a hearing aid.
摘要翻译：包括频移器（20）的助听器具有用于检测输入信号中的第一频率和第二频率的装置（22）。基于第一和第二检测频率之间的固定关系的存在，移频器（20）将输入信号的第一频率范围转换到输入信号的第二频率范围。用于检测第一和第二频率之间的固定关系的装置（34,35,36）用于控制变频器（20）。提供了一种用于检测有声和无声语音的存在的语音检测器（26），用于抑制浊音语音信号的转置以便保留语音共振峰。在助听器中以这种方式转置频带的目的是使助听器的用户听到无声频率，同时保持信号的原始包络，谐波相干性和语音清晰度。本发明还提供一种用于移动助听器中的输入信号的频率范围的方法。

摘要： A hearing aid fitting system (400) adapted for providing sound samples illustrating the impact on sound quality from a hearing aid system defect and a method of providing such sound samples. The invention also relates to a hearing aid system and computer program code capable of carrying out such a method of providing sound samples illustrating the impact on sound quality from a hearing aid system defect and methods of operating and fitting hearing aid systems. The method of operating a hearing aid system comprises identifying the hearing aid system type, selecting a hearing aid system defect (e.g., ear wax congestion, incorrect sound tube dimensions, incorrect positioning), and providing a sound sample illustrating the impact of the defect on the sound quality. The sound sample(s) may be retrieved from a memory, or a filter based on a electro-acoustical model of the (defect) hearing aid is used.
