Active Noise Attenuation Bw
A new method for globallw reducing the amount of unwanted Power radiated bv acoustic sourcesy bw means of active devices, is Proposed. After examining PreviouslY reported passive and active noise attenuating technioues, and finding them to be unsuitable for some applications, a new method is Proposed. The scheme involves Placin an attenuating source close to the noise sourcer driven in such a w...
متن کاملImplementation of decentralized active control of power transformer noise
The active noise control of sinusoidal sound in free space has received considerable attention in the last few years. In a number of practical situations, the sound radiated in free space by extended sources needs to be globally reduced. This is the case of electrical power transformers, for example [1]. Nelson and Elliott have demonstrated that sound power attenuation can be achieved by active...
متن کاملActive structural acoustic control of impact noise
Industrial machines like punching machines and presses can generate structure-borne impact noise, with noise levels exceeding the tresholds, imposed by legal regulations on noise emission. This paper presents an approach of non-collocated active structural acoustic control of transient noise, produced by a repetitive impact excitation. Although there is a significant difference in nature betwee...
متن کاملActive Acoustic Noise Control in Ducts
In this paper existing classical and advanced techniques of active acoustic noise cancellation (ANC) in ducts are collected and compared. The laboratory plant used in experience showed a linear behaviour and so the advanced techniques were not used. Due to delay on the plant, the feedback classical techniques could not be applied. The best results were obtained with the modified filtered-refere...
متن کاملCoating for an Underwater Active Acoustic Attenuation Control System
A multilayer encapsulated coating has been developed for underwater acoustic attenuation purposes. This coating provides an option for electronically activating encapsulated piezoelectric devices to increase the coatings passvie sound attenuation performance through active control methods. These methods include the ability to sense the incident and reflected acoustic pressure field and produce ...
