摘要： A method of forming a sound attenuator around a compressor of an air conditioning system includes covering the compressor with a flexible protective cover and depositing a plurality of materials proximate an outer surface of the flexible protective cover such that at least some of the plurality of materials can chemically react to create a self-forming foam that abuts at least some of the flexible protective cover to thereby create the sound-attenuating structure around the compressor.

摘要： To provide a noise control system capable of generating a noise cancellation field where noise is reduced at a desired position in a space. An error scanning filter generates a noise cancellation signal using an adaptive control algorithm based on error scanning, the signal having a phase opposite to that of an acoustic signal component detected by a reference sensor. A control speaker radiates the noise cancellation signal to create a noise cancellation field near the head of a person receiving sound.

摘要： An active noise control (ANC) system may be implemented to both sides of a fan, such that both directions of the noise emitting are treated to reduce the overall noise. The impact on airflow is minimal, and the technique is very effective in a broad range of low frequencies. Passive sound-absorbing materials may be included for attenuation of high frequencies. The resulting quiet fan produces a low level of noise compared to any other device based on fan, which produces the same capacity of airflow. The quiet fan may be incorporated in any mechanical system which requires airflow induction such as: computers, air conditioners, machines, and more.

摘要： Disclosed is a sound masking system including an airflow unit housing at least one speaker generating a masking sound field. The airflow unit is often an air diffuser set into a conventional suspended ceiling comprised of ceiling tiles. The air diffuser provides an acoustic hole in the ceiling plane whereby sound can travel into the room unencumbered by the plane of ceiling tiles. The speaker is housed within the air diffuser and is directed into the room to be treated. The speaker is capable of producing sound waves in a frequency that masks the human voice.

摘要： An apparatus for natural ventilation of a room, with a room delimited by walls. At least one door or one window includes a fixed stationary frame surrounding a movable opening frame, a ventilation passage provided on the door or the window and which communicates between the outside of the room and the inside of the room in such a way as to allow natural ventilation between the outside and inside of said room, and a noise absorber capable of attenuating sound waves propagating in the ventilation passage, the attenuation being realized by the generation of a counter-noise which is superimposed on the sound waves or by absorbing all or part of said sound waves.

摘要： An conditioner including a compressor that compresses refrigerant, an outdoor unit fan that blows out the air heat-exchanged by an outdoor heat exchanger, a noise sensor that measures noise, a data part that saves noise data measured by the noise sensor, a control part that performs a low noise operation by distinguishing between ambient noise and noise made by the air conditioner based on noise measurements from the noise sensor, wherein the control part sets a target noise level according to the ambient noise, changes the operational settings of the compressor and outdoor unit fan, and controls the operation to ensure that the noise from the air conditioner does not exceed an environmental noise regulatory value.
