    Abstract: A method and a system of noise suppressing an audio signal comprising a combination of at least two audio system input signals each having a sound source signal portion and a background noise portion, the method and system comprising steps and means of: Extracting at least two different types of spatial sound field features from the input signals such as discriminative speech and/or background noise features, computing a first intermediate spatial noise suppression gain on the basis of the extracted spatial sound field features, computing a second intermediate stationary noise suppression gain, combining the two intermediate noise suppression gains to form a total noise suppression gain, wherein the two intermediate noise suppression gains are combined by comparing their values and dependent on their ratio or relative difference, determining the total noise suppression gain, applying the total noise suppression gain to the audio signal to generate a noise suppressed audio system output signal.

    Abstract: A method of and a system for synchronizing isochronous audio data frames provided by a USB interface to a clock of a wireless RF communication device is provided. The USB interface and the wireless RF communication device are connected via an I2S link, the method comprising receiving the isochronous audio data frames and the wireless RF communication device clock in a streaming controller, phase locking the isochronous audio data frames to a USB interface clock, counting start-of-frame pulses of the phase locked isochronous audio data frames, comparing the counted start-of-frame pulses with the wireless RF communication device clock to determine a difference signal, the difference signal triggering a synchronization event code when a threshold difference has been reached, rate matching the isochronous audio data frames to the wireless RF communication device clock upon receiving the synchronization event code.

    Abstract: A noise dosimeter (xOO) for monitoring the exposure to noise of a user wearing a headset is described. The noise dosimeter includes a housing to be worn external to the ear of the user, an earpiece (xO1) for placement in or near an ear canal of the user, a microphone transducer, and a signal transmission means (xO3) for transmission of a signal from the earpiece (xO1) to the housing. The earpiece (xO1) comprises sound collection means (xO4) for collecting sound emitted from a speaker of the headset, and the housing comprises signal processing circuitry for processing and accumulating signals from the microphone transducer in order to evaluate a user's exposure to noise when using the headset. The noise dosimeter can be integrated in a headset.
