Abstract: ANR headphones generate a sound signal, and include a loudspeaker, an external microphone configured to detect an ambient noise signal, and an internal microphone configured to detect a residual noise signal within an ear canal of the user. Moreover, the ANR headphones have an acceleration sensor configured to generate an acceleration signal indicative of accelerations experienced by the ANR headphones. A controller of the ANR headphones is configured to generate a loudspeaker signal based on a composite compensation signal. The composite compensation signal is a combination of an ambient noise compensation signal based on the ambient noise signal, a residual noise compensation signal based on the residual noise signal and an acceleration compensation signal based on the acceleration signal.

Abstract: An audio controller for an active noise reduction, ANR, reduces an ambient noise signal. The audio controller includes processing circuitry configured to provide a fixed ANR filter configured to generate a first noise reduction signal. Moreover, the processing circuitry is further configured to provide an adaptive ANR filter. The adaptive ANR filter includes one or more adjustable filter coefficients for adapting the adaptive ANR filter and the adaptive ANR filter is configured to generate a second noise reduction signal. The processing circuitry is further configured to generate a total noise reduction signal as an adjustable weighted linear combination of the first noise reduction signal and the second noise reduction signal.

Abstract: The invention relates to the technical fields of binaural audio rendering and, to this end, estimation of room acoustic parameters like reverberation time. In particular, the invention provides a device and method for estimating such acoustic parameters. The device is configured to record an acoustic signal, particularly a speech signal, to estimate a frequency-dependent reverberation time in a lower frequency range based on the recorded acoustic signal, and to extend the frequency-dependent reverberation time to a higher frequency range based on a predetermined model to obtain an extended frequency-dependent reverberation time. Virtual 3D audio can thus be adapted to a real room.
