摘要： A noise-cancelling headphone 1 includes a headphone unit (14), a baffle plate (13) to which the headphone unit is attached, an ear pad (12) attached to the baffle plate, a housing (11) attached to the baffle plate, a first microphone (16) that collects external noise, a first buffer amplifier unit (151) that performs impedance conversion to a signal from the first microphone and output the impedance-converted signal, a second microphone (17) that collects internal noise, a second buffer amplifier unit (152) that performs impedance conversion to a signal from the second microphone and outputs the impedance-converted signal, and a noise-cancelling signal generating circuit (154) that generates a noise-cancelling signal, based on a combined signal by combining the signal from the first buffer amplifier unit with the signal from the second buffer amplifier unit.

摘要： The sound collection system includes: a first beamformer that outputs a first signal obtained by emphasizing sound coming from a direction within a first range, among sound arriving at a plurality of microphones, more than sound coming from other directions; a second beamformer that outputs a second signal obtained by emphasizing sound coming from a direction within a second range more than sound coming from other directions; a sound source direction detecting part that detects a sound source direction generating sound arriving at the plurality of microphones; and a directivity control part that causes the second beamformer to output the second signal if it is determined that a change angle per unit time of the direction of the sound source detected by the sound source direction detecting part is equal to or greater than a threshold while the first beamformer is outputting the first signal.
