Noise Control of Vacuum Cleaners

HCL suggests solutions to reduce airborne noise being emitted by vacuum cleaners. It has been seen that blowers used in vacuum cleaners are the main source of airborne noise and blade wakes are unavoidable in turbo machines.Focus of this whitepaper is to understand how to reduce sound intensity of vacuum cleaners and studying its effects on human hearing. ERS division in HCL proposes the design of a spiral enclosure for the blower in the vacuum cleaner. HCL suggests solutions to reduce airborne noise being emitted by vacuum cleaners.
