摘要： The present method comprises: providing a feedforward microphone outside of each earphone of the active noise-reduction earphones; detecting an amount of external noise by using the feedforward microphone; calculating a weighted energy of a noise signal; and determining whether it is needed to activate the active noise-reduction system based on the weighted energy. When the active noise-reduction control is needed, calculating energy values of two sub-bands, corresponding to the feedforward noise-reduction amount and the feedback noise-reduction amount respectively, in the noise signal, thereby determining the noise-reduction amounts of the feedforward noise reduction system and the feedback noise-reduction system, and controlling the earphone to perform corresponding feedforward noise reduction and feedback noise reduction. Compared with the existing active noise-reduction technologies with a fixed noise reduction, the present invention can optimize the noise-reduction effect.

摘要： Various aspects include a wearable audio device having active noise reduction (ANR). In some cases, an ANR system for a wearable audio device includes: a fixed filter that receives a signal from a feedback microphone and outputs a noise reduction signal, where the fixed filter is configured to provide ANR with a nominal loop gain; and a tunable filter that outputs an adjusted noise reduction signal by modulating the nominal loop gain in response to low frequency noise being detected in the noise reduction signal, where modulating the nominal loop gain includes reducing low frequency ANR performance.

摘要： A control signal filter 2 receives a sound source signal determined by a control frequency specified in conformity with the vibration/noise source that produces vibration/noise, and outputs a control signal. A filter coefficient update unit 4 updates coefficients of the control signal filter 2 in response to a sound source signal and an error signal. A signal-to-interference ratio measuring unit 5 outputs a signal-to-interference ratio determined from the vibration/noise and the interference contained in the error signal in response to the control frequency and error signal. An update controller 6 adjusts an update step of the filter coefficient update unit 4 in accordance with the signal-to-interference ratio.
