SIMULTANEOUSLY ATTENUATING HIGH-FREQUENCIES AND AMPLIFYING LOW-FREQUENCIES OF UNDERWATER SOUNDS
A noise-abatement system includes a frame defining a predetermined frame volume, an acoustic pressure source attached to the frame, and a plurality of resonators attached to the frame surrounding the acoustic pressure source. The resonators can be formed in modular resonator groups. The resonators have an individual resonance frequency that can be tuned to the transition frequency between relatively high sound frequencies, produced by the acoustic pressure source, to be attenuated and relatively low frequencies, produced by the acoustic pressure source, to be amplified. The resonators attenuate the relatively high sound frequencies using their individual resonance frequency. The noise-abatement system has a collective resonance frequency that can amplify the relatively low sound frequencies.
