Citywide Speaker Arrays for Urban Noise Cancellation

Posts discuss a “city-scale noise-canceling headphone” concept that would use speaker arrays to directionally cancel urban noise around pedestrians. The idea is presented as theoretically grounded by the Kirchhoff-Helmholtz integral theorem, though perfect cancellation is unrealistic with discrete speakers; suggested applications include public-space hearing assistance, quieter machine design, and acoustic levitation.
