A device includes a housing and a core configured to be secured within the housing. The core includes a microphone configured to detect a sound signal. The core also includes a control board configured to generate a noise-canceling sound signal based on the sound signal and a set of transfer functions. The core further includes a speaker configured to deliver the noise-canceling sound signal. The device also includes a fastener configured to connect the housing to an air filter of an intake vent of an enclosure of a power generation unit.

Active noise cancelation systems and devices

A method to suppress noise emanating from an electrical power generator including the steps of: receiving sound emanating from the electrical power generator, wherein the sound is received in a duct for cooling air having passed through the generator; analyzing the received sound and, based on the analysis, generating a sound signal which represents a destructive sound to the received sound, and broadcasting a destructive sound into the duct, wherein the destructive sound corresponds to the sound signal.

Electrical power generator with active noise cancellation in ventilation ducts

A system includes an Active Noise Control (ANC) module unit configured to be installed within an air intake or exhaust of a power generation unit. The ANC module unit includes an ANC housing shaped to fit within the air intake or exhaust, an ANC core configured to be secured within the ANC housing, which includes a microphone configured to detect a sound generated by the power generation unit, a control board configured to control the noise-canceling sound based on the sound signal from the microphone and a set of pre-determined noise reduction transfer functions, and a first speaker configured to deliver a first noise-canceling sound to the air intake or exhaust.

Active noise control system

A system configured to thermally regulate heat dissipation of a power plant system (e.g. steam turbine, gas turbine compressor, intercooler or other fluidic thermal source, etc.) and acoustically attenuate operation of an air cooled heat exchanger via sound reflection, sound absorption, sound diffraction, and/or active noise cancellation is disclosed. In one embodiment, a system includes: a set of inner barriers; a base barrier disposed beneath the set of inner barriers; a set of outer barriers disposed about the base barrier and the set of inner barriers, the set of outer barriers including a top surface located above a bottom surface of the set of inner barriers; a heat exchanger fluidly connected to a power generation system and disposed within the set of inner barriers; and a set of fans disposed within the set of inner barriers and configured to form a flow of air through the set of inner barriers.
