Title:
SYSTEMS AND METHODS FOR ATTENUATING ACOUSTIC WAVES
Document Type and Number:
WIPO Patent Application WO/2024/054990
Kind Code:
A3
Abstract:
An acoustic filter can include a first substrate including a first plurality of holes directed, therethrough, a second substrate including a second plurality of holes directed therethrough, a chamber defined between the first substrate and the second substrate, and a membrane positioned within the chamber. The membrane can have a dimension other than the thickness of the membrane that can be less than a corresponding dimension of the chamber. The acoustic filter can be configured to attenuate a first acoustic wave that passes through the acoustic filter, the first acoustic wave can have a first amplitude above an amplitude threshold. The acoustic filter can be configured to passthrough a second acoustic wave without substantially attenuating the second acoustic wave, the second acoustic wave can have a second amplitude below' the amplitude threshold.
