Abstract: Feedback whistling and external tonal signals are distinguished during feedback suppression. For that purpose an adaptation increment of an adaptive filter of a hearing apparatus for feedback reduction is controlled. A sound signal is picked up by a microphone and a microphone signal is output, from which an earpiece signal for an earpiece is generated. An adaptive filter reduces a feedback signal in the microphone signal. To this end an autocorrelation value of sampled values of the microphone signal, between which a time difference exists, is obtained, and the adaptation increment of the adaptive filter is controlled based on the autocorrelation value. A frequency of an output signal obtained on the basis of the microphone signal is shifted while creating the earpiece signal and the time difference for obtaining the autocorrelation value is controlled as a function of the shifting of the frequency of the microphone signal.

Abstract: A full-audio-range speaker has a box, at least one dynamic speaker unit, and a vibration speaker. The box has multiple side walls and at least one wall hole. The at least one dynamic speaker unit is mounted in the box and has a sound hole aligned with the at least one wall hole. The vibration speaker is mounted through the box. The at least one dynamic speaker unit and the vibration speaker respectively improve midrange, treble, and bass performances of the full-audio-range speaker. Therefore, the full-audio-range speaker can have relatively good midrange, treble, and bass performances simultaneously.

Abstract: A novel system and method for adjusting the dynamic range of an audio recording or signal, which does not require user manipulation of threshold and ratio (and other parameters). Unlike prior audio compressors or limiters, the present invention provides for the ability to set the dynamic range without complicated user settings and knowledge. The process can be done automatically by a computer or processor.

Abstract: An approach is described for evaluating a selected hearing stimulation strategy in a hearing impaired patient. A healthy neurogram represents a normal auditory neural response to a selected sound input by a healthy auditory system. An impaired neurogram represents an impaired auditory neural response to the selected sound input by a hearing impaired patient auditory system using the hearing stimulation strategy. The impaired neurogram is compared to the healthy neurogram based on: i. partitioning the neurograms into corresponding temporal and frequency domain tiles, ii. determining local variability between corresponding individual tiles by comparison of selected tile features, iii. determining global variability between the neurograms by weighted averaging of the individual tile comparisons, and iv. developing from the local and global variabilities a perception estimate representing effectiveness of the selected hearing stimulation strategy in approaching normal healthy hearing for the implanted patient.

Abstract: A personal audio device, such as a wireless telephone, includes noise canceling circuit that adaptively generates an anti-noise signal from a reference microphone signal and injects the anti-noise signal into the speaker or other transducer output to cause cancellation of ambient audio sounds. An error microphone may also be provided proximate the speaker to measure the output of the transducer in order to control the adaptation of the anti-noise signal and to estimate an electro-acoustical path from the noise canceling circuit through the transducer. A processing circuit that performs the adaptive noise canceling (ANC) function also detects frequency-dependent characteristics in and/or direction of the ambient sounds and alters adaptation of the noise canceling circuit in response to the detection.
