An improved hearing aid device adapted for use within the ear canal of the CIC (Completely In the ear) and of the partially exposed ITC (In The Canal) type. This aid consists of a system of integrated parts allowing an air gap to substantially surround the hearing aid shell and air passages which communicate with the inner ear minimizing occlusion sensations and providing the user with an enhanced natural hearing experience. A key aspect of this device is the provision of air passages in the mounting insert which securely positions the hearing aid shell in the wearer's canal. These passages are designed to stay open after insertion of the aid in the ear canal. In use, unamplified sound from the outside passes around the hearing aid shell, through the air passages in the mounting insert blending with the amplified sound emanating from the receiver. The area of air passages in the mounting insert can be tailored by the technician adapting to the hearing loss characteristics of the user. Surprisingly, acoustic feedback is mitigated in spite of the openness of this novel design.

A personal audio device, such as a wireless telephone, includes an adaptive noise canceling (ANC) circuit that adaptively generates an anti-noise signal from a reference microphone signal that measures the ambient audio and an error microphone signal that measures the output of an output transducer plus any ambient audio at that location and injects the anti-noise signal at the transducer output to cause cancellation of ambient audio sounds. A processing circuit uses the reference and error microphone to generate the anti-noise signal, which can be generated by an adaptive filter operating at a multiple of the ANC coefficient update rate. Downlink audio can be combined with the high data rate anti-noise signal by interpolation. High-pass filters in the control paths reduce DC offset in the ANC circuits, and ANC coefficient adaptation can be halted when downlink audio is not detected.

Three-dimensional sound apparatus

Номер: US20120308056A1

Автор: Toshiaki Nakayama

Принадлежит: Denso Corp

Binaural recording stored in a reproducing-use sound source portion is recorded by giving an ultrasonic modulated sound from a recording-use ultrasonic wave speaker to a dummy head. A cross talk is suppressed; thus, the binaural recording is obtained with clear sonic localization information while localization of pronunciation orientation can be improved. Further, the sounds generated by ultrasonic modulating the binaural recording in the reproducing-use sound source portion are given towards left and right ears of a driver from left and right reproducing-use ultrasonic wave speaker units, respectively, arranged at positions distant from the head of the driver. “Sonic 3D information” relative to the localization of pronunciation orientation is given accurately to the ears of the driver. Even in a vehicle compartment tending to provide reflected sounds or muffled sounds, an accurate “sonic localization” can be achieved without a headphone.

A voice signal processor detects background noise sections to reflect characteristics of the background noise on the Wiener filter coefficient to be used for suppressing noise components of input voice signals. In the voice signal processor, directivity signal generators form directivity signals having a directivity pattern. The directivity signals are used by a coherence calculator to obtain coherence, which is in turn used by a targeted voice section detector to detect a targeted voice section. A background noise section detector detects background noise sections containing no voice signal. When a background noise section is detected, a WF adapter uses characteristics of background noise in the detected temporal section to calculate a new WF coefficient.

Spectrally Uncolored Optimal Crosstalk Cancellation For Audio Through Loudspeakers

Номер: US20130163766A1

Автор: CHOUEIRI Edgar Y.

Принадлежит:

A method and system for calculating the frequency-dependent regularization parameter (FDRP) used in inverting the analytically derived or experimentally measured system transfer matrix for designing and/or producing crosstalk cancellation (XTC) filters relies on calculating the FDRP that results in a flat amplitude vs frequency response at the loudspeakers, thus forcing XTC to be effected into the phase domain only and relieving the XTC filter from the drawbacks of audible spectral coloration and dynamic range loss. When the method and system are used with any effective optimization technique, it results in XTC filters that yield optimal XTC levels over any desired portion of the audio band, impose no spectral coloration on the processed sound beyond the spectral coloration inherent in the playback hardware and/or loudspeakers, and cause no (or arbitrarily low) dynamic range loss. 1. A method for filtering audio signals to cancel crosstalk in an audio system comprising the steps ofinverting a transfer matrix or function of the audio system;using information from the inverted transfer matrix or function to calculate a frequency-dependent regularization parameter that when applied to audio signals produces a flat frequency response at any of the loudspeakers of the audio system over an audio band or a portion thereof;using said calculated frequency-dependent regularization parameter to calculate the pseudo inverse of said transfer matrix.2.
