摘要： Disclosed herein, among other things, are apparatus and methods for a binaurally coordinated frequency translation for hearing assistance devices. In various method embodiments, an audio input signal is received at a first hearing assistance device for a wearer. The audio input signal is analyzed and a first set of target parameters is calculated. A third set of target parameters is derived from the first set and a second set of calculated target parameters received from a second hearing assistance device using a programmable criteria, and frequency lowered auditory cues are generated using the third set of target parameters. The derived third set of target parameters is used in both the first hearing assistance device and the second hearing assistance device for binaurally coordinated frequency lowering.

摘要： Described herein are techniques for artificially enhancing spaciousness in a hearing aid to improve the music listening experience. Such spatial enhancement is produced by doing signal processing in the hearing aid that mimics the acoustic effects of well-designed concert halls. The same techniques can also be applied to improving the experience of listening to recorded music reproduced and amplified over a speaker system, or to music streamed to the direct-audio input of a hearing aid.

摘要： A hearing assistance system for delivering sounds to a listener provides for subjective, listener-driven programming of a hearing assistance device, such as a hearing aid, using a perceptual model. The system produces a distribution of presets using a perceptual model selected for the listener and allows the listener to navigate through the distribution to adjust parameters of a signal processing algorithm for processing the sounds. The use of the perceptual model increases the potential of fine tuning of the hearing assistance device available to the listener.

摘要： Disclosed herein, among other things, is a system for frequency translation by high-frequency spectral envelope warping in hearing assistance devices. The present subject matter relates to improved speech intelligibility in a hearing assistance device using frequency translation by high-frequency spectral envelope warping. The system described herein implements an algorithm for performing frequency translation in an audio signal processing device for the purpose of improving perceived sound quality and speech intelligibility in an audio signal when presented using a system having reduced bandwidth relative to the original signal, or when presented to a hearing-impaired listener sensitive to only a reduced range of acoustic frequencies.
