Patent Number: 245028
Title: ULTRA LOW FREQUENCY ACOUSTIC VECTOR SENSOR
Inventors: Donskoy; Dimitri ; et al
Abstract: An acoustic vector sensor mounted in a housing is provided for measuring ultra low frequency acoustic wave particle velocities in a liquid, comprising a horn for amplifying the acoustic wave particle velocities, and a neutrally buoyant object supported in a liquid contained in the horn. The neutrally buoyant object, in reacting to the amplified acoustic wave particle velocities, produces displacements that are sensitively measured.
