A first microphone picks up noise radiated by a noise source to the listening position and generates a first microphone signal. A second loudspeaker disposed at a second position that radiates sound. A second microphone that generates a second microphone signal. A third microphone disposed at a third position that generates a third microphone signal. An active noise cancellation (ANC) controller that receives the third microphone signal and at least one of the first and second microphone signals and that provides a loudspeaker input signal. A distance between the third position and the first position equals a distance between the third position and the second position such that the first, second and third microphones form corners of an isosceles triangle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Silent zone generation","description":"A system for generating silent zones at a listening position comprises a first loudspeaker disposed at a first position and configured to radiate sound that corresponds to a sound signal.
