Abstract: Example embodiments describe an apparatus, method and computer program relating to cancellation of ultrasonic signals. The apparatus may comprise means for providing first data derived from a signal received by a microphone of a user device and means for providing second data representing mechanical oscillations within a gyroscope of the user device. The apparatus may also comprise means for detecting, based on the first data and the second data, that the signal received by the microphone comprises an ultrasonic signal, means for processing third data to generate fourth data representing an estimate of one or more audible sounds in the first data, wherein the third data is either the second data or is derived from the second data, and means for subtracting the fourth data from the first data to provide fifth data.
