摘要： A device for detecting the presence of wind noise in an array of microphones including two or more separate sound inlet openings, and a sound to electrical converting element or microphone in relation to each sound inlet opening. The microphones each generate time dependent signals which are fed to a signal processing device that provides one or more output signals. The signal processing device has means for generating a time dependent cross correlation function between a first and a second microphone signal, and means for generating a signal corresponding to a time dependent auto correlation function of either the first or the second of the microphone signals. Further, the signal processing device has means for comparing the values of the auto correlation function and the cross correlation function and the means for comparing are arranged to detect the condition that the auto correlation function is substantially higher than the cross correlation function, whereby the condition is indicative of the presence of wind noise.

摘要： A hearing aid includes a signal path having an input transducer, a processor and an output transducer, the hearing aid further including a radio frequency receiver, where the receiver includes a single crystal oscillator providing a single oscillator frequency and where means are provided for generating a further number of receiving frequencies by transforming the oscillator frequency to the desired receiving frequencies. The hearing aid and the RF receiver may be separate or integrated. The invention further relates to a separate element comprising a RF receiver, the separate element being adapted for mounting on a hearing aid.

摘要： An electronic circuit, a digital audio component, an interface system and a method for streaming PDM data from or to at least one audio element are provided. The electronic circuit comprises a VDD connection for receiving a VDD potential, a GND connection for receiving a potential numerically lower than said VDD potential, a CLK connection for receiving a clock signal having a high and a low part, a DATA connection for communicating said PDM data to or from a host and/or another such electronic circuit, an L/R connection for receiving a DC potential designating whether to communicate substantially synchronously with said high part or said low part of said clock signal. The electronic circuit further comprises an I/O circuit configured for communicating control data via said L/R connection.
