Abstract

An acoustic device with a manifold architecture is described. The acoustic device includes a primary waveguide and a manifold. The primary waveguide has a first end, coupled to an acoustic sensor, and a second end, a port open to a local area. The port receives airflow from the local area that includes sound pressure waves from a sound source and turbulent pressure waves. The sound pressure waves and a first portion of the turbulent pressure waves are detected by the acoustic sensor. The manifold includes a plurality of waveguides that are coupled to a portion of the primary waveguide between the first end and second end. The plurality of waveguides has openings to the local area. The manifold vents a second portion of the turbulent pressure waves through the openings, and the second portion of the turbulent pressure waves is larger than the first portion of the turbulent pressure waves.
