Appl. No.:

09/567860

Inventors:

Brent Edwards - San Francisco CA

Assignee:

GN ReSound AS - Taastrup

International Classification:

H04R 300

US Classification:

381122, 381 92, 381 7112, 704226

Abstract:

The present invention comprises an adaptive directionality dual microphone system in which the time domain data from the first and second microphones is converted into frequency domain data. The frequency domain data is then manipulated to produce a noise-canceled signal which is converted in an Inverse Fourier Transform block into noise-cancel time domain data.

International Classification:

H04R 2500

US Classification:

381318, 381317

Abstract:

A feedback cancellation system for a hearing instrument is described. The feedback cancellation system includes both a constrained adaptive filter, the constrained adaptive filter can be constrained by initiation coefficients, as well as an adaptive gain modification. The adaptive gain modification allows the feedback cancellation to respond to substantially different environments from the test environment used to derive the initiation coefficients for the constrained adaptive filter.

International Classification:

H04M 9/08

US Classification:

Abstract:

Techniques for suppressing large echo due to nonlinearity, instable adaptive filter, and so on. An echo cancellation system includes an echo canceller unit, a nonlinear echo detection unit, and a nonlinear echo suppression unit. The echo canceller unit (e. g. , an adaptive filter) receives a reference signal and a near-end signal, derives an echo estimate signal based on the reference and near-end signals, cancels a portion of echo in the near-end signal based on the echo estimate signal, and provides an intermediate signal having residual echo. The nonlinear echo detection unit detects for large nonlinear echo in the echo estimate signal. The nonlinear echo suppression unit suppresses large nonlinear echo in the first intermediate signal based on a variable gain, which may be adjusted lower if large nonlinear echo is detected and higher otherwise.

International Classification:

H04B 15/00

US Classification:

381 942, 381 941, 381 943, 381 948

Abstract:

Various embodiments of systems and methods for reducing audio noise are disclosed. One or more sound components such as noise and network tone can be detected based on power spectrum obtained from a time-domain signal. Results of such detection can be used to make decisions in determination of an adjustment spectrum that can be applied to the power spectrum. The adjusted spectrum can be transformed back into a time-domain signal that substantially removes undesirable noise(s) and/or accounts for known sound components such as the network tone.

Abstract:

The subject matter of this specification can be embodied in, among other things, a method that includes generating, within a web-accessible document, a parent container document associated with a first Internet domain and one or more child container documents within the parent container document and associated with a second Internet domain. The method also includes receiving, by the parent container document, information requested from a server associated with the first Internet domain, and communicating the information from the first Internet domain to the second Internet domain using the parent container document associated with the first Internet domain to transmit the information to the one or more child container documents associated with the second Internet domain.

US Classification:

704209, 704225, 704226, 704233

Abstract:

An adaptive audio system can be implemented in a communication device. The adaptive audio system can enhance voice in an audio signal received by the communication device to increase intelligibility of the voice. The audio system can adapt the audio enhancement based at least in part on levels of environmental content, such as noise, that are received by the communication device. For higher levels of environmental content, for example, the audio system might apply the audio enhancement more aggressively. Additionally, the adaptive audio system can detect substantially periodic content in the environmental content. The adaptive audio system can further adapt the audio enhancement responsive to the environmental content.
