摘要： An outdoor unit of an air conditioner includes a compressor surrounded by a noise reducing structure. The noise reducing structure includes a bottom sheet attached tightly to a lower surface of the compressor, and a dome-shaped top sheet enclosing the sides and top of the compressor. Each of the top sheet and the bottom sheet is comprised of a noise-reflecting material, and a noise-absorbing material attached to the inner side of the noise-reflecting material. The top sheet is formed of two sections joined together at a parting line lying in a vertical plane.

摘要： A home appliance, such as a clothes washing machine, has a source of noise and an acoustic insulator. The source of noise moves between a first position and a second position during operation of the appliance. The acoustic insulator has a movable portion that moves with the source of noise between the first position and the second position during operation of the appliance and an interface that remains substantially stationary as the source of noise moves between the first and second positions.

摘要： In a low noise refrigerator, a compressor constituting a noise source is arranged within a machine chamber provided with an opening in one location, which chamber has a one-dimensional duct construction in which its cross-sectional dimension is small relative to the wavelength of the noise which is to be reduced. A vibration pick-up is located in the vicinity of the compressor. The vibration pick-up detects compressor vibrations which correlate to the compressor noise of the compressor. There is provided a control circuit that processes the output signal of the vibration pick-up. In the machine chamber, a sound generator is driven by the output signal of the control circuit to generate a control sound, so that the compressor noise which tries to issue from the opening is canceled by the control sound.
