These and other future restrictions on exterior noise of high-speed and intercity trains will require that train manufacturers implement noise control measures early in the design phase.
In an attempt to alleviate these problems, the majority of aerodromes implement noise abatement procedures designed to route aircraft away from noise sensitive areas, and more than 50 are required by the government to provide consultative facilities in which local concerns can be raised with aerodrome operators.
In order to implement noise in the continuous model, we followed a procedure similar to the one indicated in Eq. (2); namely, with a probability η, each gene will disobey its Boolean function Fn, replacing it by 1−Fn; however, since the system in this case is governed by differential equations, this "perturbation" will occur during a finite time interval Δtp, rather than being instantaneous.
In these cases you should take the time to learn and implement noise reduction in post processing.
"The U.S. has long since given up its lead in regulating noise, and because of that there has been no consistency in implementing local noise regulations," Huber says.
This problem can be resolved using optical and electronic filters [4] and implementing a noise canceling algorithm at the receivers [3].
In an effort to determine optimal strategies on a European level, the EU fifth framework programme has co-financed the Strategies and Tools to Assess and Implement noise Reducing measures for Railway Systems (STAIRRS) project.
The EU and Union of Railways (UIC) sponsored project Strategies and Tools to Assess and Implement noise Reducing measures for Railway Systems (STAIRRS) recognized this need and developed a tool, with which such optimal solutions can be obtained for entire railway networks.
Also certain templates of memristive neural networks are established to implement the noise cancellation.
In this paper, we implement the noise cancellation method in FPGA as hardware to perform real-time speech enhancement.
