Abstract: PROBLEM TO BE SOLVED: To provide a signal processing method for separating one or more desired signals from mixed signals obtained by superimposing and linearly synthesizing several source signals including a signal from an information source and signals from one or more interference sources as an information signal.SOLUTION: A method, device and system for signal source separation include a plurality of coefficient values converged on the basis of each of a plurality of M channel signals. Each of the plurality of M channel signals is based on signals generated by M pieces of converters in response to at least one information source and at least one interference source. In several examples, a plurality of converged coefficient values are used for generating an information output signal and interference output signal by filtering the M channel signals.

Abstract: An electronic device for controlling noise is described. The electronic device includes a force sensor for detecting a force on the electronic device. The electronic device also includes noise control circuitry for generating a noise control signal based on a noise signal and the force. Another electronic device for controlling noise is also described. The electronic device includes a speaker that outputs a runtime ultrasound signal an error microphone that receives a runtime ultrasound channel signal and noise control circuitry coupled to the speaker and to the error microphone. The noise control circuitry determines at least one calibration parameter and determines a runtime channel response based on the runtime ultrasound channel signal. The noise control circuitry also determines a runtime placement based on the runtime channel response and the at least one calibration parameter and determines at least one runtime active noise control parameter based on the runtime placement.

Abstract: A microphone port design for a handheld device is disclosed. The microphone port design includes an elongated channel disposed in a first surface of the handheld device. A microphone port is located within the channel to reduce unwanted noise caused by air pressure build up around the microphone port opening due to coverage of the opening by a user's finger.
