Abstract: An electronic device for controlling noise is described. The electronic device includes a force sensor for detecting a force on the electronic device. The electronic device also includes noise control circuitry for generating a noise control signal based on a noise signal and the force. Another electronic device for controlling noise is also described. The electronic device includes a speaker that outputs a runtime ultrasound signal an error microphone that receives a runtime ultrasound channel signal and noise control circuitry coupled to the speaker and to the error microphone. The noise control circuitry determines at least one calibration parameter and determines a runtime channel response based on the runtime ultrasound channel signal. The noise control circuitry also determines a runtime placement based on the runtime channel response and the at least one calibration parameter and determines at least one runtime active noise control parameter based on the runtime placement.

Abstract: A method for mapping a source location by an electronic device is described. The method includes obtaining sensor data. The method also includes mapping a source location to electronic device coordinates based on the sensor data. The method further includes mapping the source location from electronic device coordinates to physical coordinates. The method additionally includes performing an operation based on a mapping.
