The invention is directed to determining a gain for an equalizer associated with an audio device. An exemplary method comprises determining a maximum audio output level allowed by an acoustic safety threshold; determining a setting of the equalizer; and adjusting a gain of the equalizer based on the setting and the maximum audio output level. The invention enables an audio device to simultaneously satisfy an acoustic safety threshold and deliver an optimum audio output level.

The present invention relates to a noise cancellation system, a headset and an electronic device. The noise cancellation system may include a loudspeaker, a first microphone, a second microphone, a housing and a processing unit. The housing may be mounted at an ear of a user, wherein the loudspeaker, the first microphone and the second microphone are installed in the housing. The processing unit may be coupled to the loudspeaker, the first microphone and the second microphone, and may be configured to generate a noise cancelling signal based on at least one of a first audio signal from the first microphone or a second audio signal from the second microphone, wherein the noise cancelling signal, when being output via the loudspeaker, at least partially compensates for environmental noise in the ear of the user.

The invention is directed to systems, methods and computer program products associated with a microphone system for receiving a sound and producing an output signal representing the sound. The microphone system has a first microphone having a first dynamic range, the first microphone to receive the sound and produce a first sound signal based on the received sound. It also has a second microphone having a second dynamic range, the second microphone to receive the sound and produce a second sound signal based on the received sound, wherein the first dynamic range and the second dynamic range overlap thereby forming a transition dynamic range and processing logic operatively coupled to the first microphone and the second microphone. The processing logic is configured to receive the first sound signal from the first microphone, receive the second sound signal from the second microphone, and generate the output signal by combining the first sound signal and the second sound signal.

A device may store a subset of a plurality of head-related transfer functions (HRTFs) for emulating stereo sound from a source in three-dimensional (3D) space, each of the HRTFs corresponding to a direction from which the stereo sound is perceived to arrive, by a user hearing the stereo sound. The device may also obtain a first direction from which first stereo sound is perceived to arrive, by the user and determine whether the subset of the plurality of HRTFs includes a first HRTF corresponding to the first direction, wherein the plurality of HRTFs include the first HRTF. Further, the device may select two HRTFs in the subset of the HRTFs, wherein directions that are associated with the two HRTFs are closer to the first direction than directions of other HRTFs in the subset of the HRTFs.
