Audible enclaves crafted by nonlinear self-bending ultrasonic beams
Abstrak
Significance Recent advancements in digital signal processing and loudspeaker array design have enabled us to experience immersive spatial audio in virtual/augmented/extended reality environments in our daily lives. However, further development in audio engineering is impeded by physical constraints stemming from the diffraction of long-wavelength audio waves. This study introduces an approach to address this issue by showcasing the creation of ultrabroadband (125 Hz to 4 kHz) and highly localized remote audio spots, referred to as audible enclaves. By marrying local acoustic nonlinearity with inaudible self-bending ultrasonic beams, the proposed technique overcomes the physical limits in linear acoustics, paving the way for possibilities in future audio engineering.
