摘要： A method and system to monitor and adjust sound waves. The system includes microphone unit, noise-cancellation circuitry, input audio source, processing unit, and microcontroller unit. The microphone unit detects ambient sound waves after turning on microphone unit. The noise-cancellation circuitry creates sound waves that are 180 degrees out of phase with the detected ambient sound waves to cancel ambient sound waves. The processing unit processes sound waves received from noise-cancellation circuitry and audio signals received from input audio source into output sound waves, and further measures quantified level of loudness of output sound waves. The microcontroller unit aggregates, and compares received quantified level of loudness of output sound waves with a pre-stored quantified value of sound waves. The processing unit adjusts output sound waves to pre-defined value of sound waves in case compared quantified level of loudness of output sound waves exceeds from the pre-stored quantified value of sound waves.

摘要： A second error microphone may be incorporated in a mobile device to allow computation of additional parameters for modifying an adaptive noise cancellation (ANC) algorithm. For example, a first and second acoustic pressure may be calculated from a first and second error microphone of the mobile device. The first and second acoustic pressure may be input to an algorithm for determining an acoustic intensity vector. The ANC algorithm may receive the acoustic intensity vector as an input, and adapt an anti-noise signal to reduce the acoustic intensity vector. Additionally, an input impedance for the error microphones may be calculated from the acoustic pressure to determine coupling between a speaker and a user's ear. The anti-noise algorithm may be adjusted or disabled when the input impedance indicates the user has removed the phone from the user's ear.

摘要： Embodiments are directed towards a speaker/microphone system. Each microphone in a microphone array generate an audio signal based on sound in a physical space. The microphone array may be arranged to logically define the physical space into a plurality of regions that have a status of active or inactive. An output signal may be generated from the audio signals, such that directional noise reduction is performed on audio signals associated with inactive regions and speech enhancement is performed on audio signals associated with active regions. A region's current status may be modified to its opposite status based on a request provided by a user. The request may be triggered by an activator or a spoken word/phrase provided by the user. An indication may be provided to the user regarding each current status for each region. The indication may also represent a quality of audio signals associated with active regions.
