Managing and controlling traffic on ramps is important because freeway entrance and exit ramps are the only facilities motorists may use to legally make connections to and from limited access facilities and as such represent the only locations where traffic entering and exiting a limited access facility can be controlled. Often, ramps are too closely spaced, do not offer adequate acceleration distances for posted speeds, or are simply overwhelmed by the increasing number of motorists that use them on a daily basis. When conditions like these exist, impacts may develop that affect the efficient and safe operation of. | KINETICS NOISE CONTROL INC. is recognized as the major producer of products and systems for the control of noise and vibration. The Company markets products under the trade name KINETICS . KINETICS products and engineered systems have been incorporated throughout major industrial and commercial buildings in the United States Canada Europe Australia and the Far East. Kinetics Noise Control s national headquarters and manufacturing facilities are located in Dublin Ohio in a 60 000 sq. ft. 5574 m facility. The Company provides products systems and solutions to everyday problems and for complex applications requiring noise and vibration control analysis. By using the Kinetics Selection Guide contained in this bulletin proper isolation can be specified by type and deflection to obtain optimum effectiveness of the isolators. By specifying deflection rather than theoretical isolation efficiency performance can be assured and can be readily verified in the field. Kinetics engineering and testing facilities are available at all times to assure that each product is tailored to meet project specifications and field conditions. Its staff of professionals welcomes the opportunity to assist in selecting and specifying the company s products and systems. Kinetics provides certified engineering drawings when requested for all products to assure compliance with project specifications. Vibration and vibration-induced noise major sources of occupant complaint have steadily increased in today s modern buildings. The problems have been compounded by lighter weight construction and by the positioning of equipment in penthouses or intermediate level mechanical rooms. Not only is the physical vibration in the structure disturbing but noise which is regenerated by the structural movement may be heard in other remote sections of the structure. Effectiveness of vibration isolators in bringing about vibration reduction is indicated by the transmissibility of the system. A typical .
