Modeling and Dynamic Analysis of an Electrical Helmholtz Resonator for Active Control of Resonant Noise
(2017-10-01)
This paper describes a theoretical and experimental investigation into an electrical Helmholtz resonator (EHR): that is, an active noise control (ANC) loudspeaker used in conjunction with a microphone and a feedback ...
Turning a loudspeaker into an active Helmholtz resonator: Underlying law, principle and design methodology
(2018-10-13)
This paper is concerned with how to turn a moving-coil loudspeaker into an active Helmholtz resonator (AHR): that is, an active noise control loudspeaker used in conjunction with a microphone and a feedback controller to ...
Brief note on the theoretical behaviour of a variable neck section helmholtz resonator cavity
(1984)
It is well known that the resonance frequency (f) of a Helmholtz resonator depends on sound speed,
neck section, neck length and on the resonator cavity volume. The purpose of this paper is to find f
when the resonator ...
