An acoustic control system for controlling acoustic noise in a duct arranged to receive fluid flow therein, the system comprising:
- a resonator arrangement for connection to the duct, the resonator arrangement comprising a plurality of resonators, wherein the resonator arrangement is configured based on a flow rate of the fluid flow in the duct.
A method of controlling acoustic noise in a duct arranged to receive fluid flow therein, comprising:
- providing a resonator arrangement for connection to the duct, the resonator arrangement comprising a plurality of resonators;
- and
- configuring the resonator arrangement based on a flow rate of the fluid flow in the duct.
A system comprising:
- a resonator arrangement for connection to a duct, the resonator arrangement comprising a plurality of resonators, wherein the resonator arrangement is configured based on a flow rate in the duct;
- wherein a resonance frequency of each resonator is based on position of the resonator relative to the duct;
- and
- wherein the resonators are arranged to provide a variation in resonance frequency of each resonator with position of the resonators relative to the duct.
