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.

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 camera input can be used by the computer to support audio spatialization or to improve audio spatialization of an application that already supports it. A computer system may to support audio spatialization, for example, by modifying the relative latency or relative amplitude of the rendered audio packets. If a sound is intended, for example, to be located on the left side of the user, then the audio channel that is rendered on the headset speaker located on the user's left ear may have a somewhat decreased latency and increased amplitude compared to the other audio channel.

In summary, this application describes a psycho-acoustically motivated, parametric description of the spatial attributes of multichannel audio signals. This parametric description allows strong bitrate reductions in audio coders, since only one monaural signal has to be transmitted, combined with (quantized) parameters which describe the spatial properties of the signal. The decoder can form the original amount of audio channels by applying the spatial parameters. For near-CD-quality stereo audio, a bitrate associated with these spatial parameters of 10 kbit/s or less seems sufficient to reproduce the correct spatial impression at the receiving end. 1.

Spectrally Uncolored Optimal Crosstalk Cancellation For Audio Through Loudspeakers

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.

In the case that a surround back left audio signal SBL and a left outside audio signal LW are included, the signal SBL is amplified and output to a surround back left SP terminal 14 a through a switch S 13 a . The signal LW is amplified and output to a left outside SP terminal 14 b through a switch S 13 c . The signal LW is supplied from a DAC 11 b to a left outside pre-out terminal 11 d through a switch S 11 c . At this point, in order to supply the signal LW to the left outside pre-out terminal 11 d , a DAC 11 c is not used, but the DAC 11 b is used. Accordingly, the DAC 11 c can be used for another signal (ex., ZONE 2 ) to decrease the number of DACs.
