Research in Tire/Pavement Noise Reduction and Safety
Noise is defined as a loud sound of any sort that is disagreeable or unwanted. Throughout the ages of civilized history, noise has been an annoying irritant to mankind. In recent years the noise level of freeways in urban and suburban areas in the United States has increased perceptibly as freeway traffic has increased and more people are living closer to freeways. To reduce such a noisy irrita...

متن کاملPhotogrammetric Pavement Detection System
This paper introduces a complex, low-cost road pavement measurement system designed primarily for pothole and crack detection. The onboard system is composed of a GPS/INS navigation unit, an image acquisition module, and a photogrammetric and imageprocessing subsystem. Due to the use of structured light and the availability of accurate navigation data, the 3D coordinates of the road points, in ...
متن کاملAn adaptive system for active noise reduction.
An adaptive system for active noise reduction in an acoustic duct is presented. The system is based on a modification of a least mean square (LMS) algorithm called filtered-U with on-line error path modelling. The system was assembled and examined on a laboratory test stand in the Laboratory of Active Noise Reduction Methods of the Central Institute for Labour Protection (Warsaw, Poland). The s...
متن کاملImplementation effective one-channel noise reduction system
This contribution addresses the problem of additive noise reduction using one-channel noise suppression system. A new implementation effective method is suggested and evaluated. The method consists of two independent parts. The noise estimation part is based on the noise matched filter producing an estimation of background noise without the need of a voice activity detector. The noise reduction...
