  A steerable parametric loudspeaker array is known for its directivity and
narrow beam width. However, it often suffers from the grating lobes due to
periodic array distributions. Here we propose the array configuration of
hyperuniform disorder, which is short-range random while correlated at large
scales, as a promising alternative distribution of acoustic antennas in phased
arrays. Angle-resolved measurements reveal that the proposed array suppresses
grating lobes and maintains a minimal radiation region in the vicinity of the
main lobe for the primary frequency waves. These distinctive emission features
benefit the secondary frequency wave in canceling the grating lobes regardless
of the frequencies of the primary waves. Besides that, the hyperuniform
disordered array is duplicatable, which facilitates extra-large array design
without any additional computational efforts.
