The tire/pavement interface zone is the origin of a major portion of the ride vibration, ride noise, and environmental noise disturbances associated with road vehicles. It is appropriate to view these separate problems as one comprehensive systems problem involving the road, the tire, the vehicle, and human response to noise and vibration stimuli. A flow chart is used to discuss the general systems problem. Main branches of the flow chart are examined based on a thorough review of the pertinent literature. Relevant and previously unpublished information is included in the paper.
A noise survey was carried out at various locations within twenty feet of a jet-engine, to determine the generated sound field. The instrumentation was such that it was possible to obtain a tape recording of the noise over a frequency range of 20–100 000 cps. The calibration of the high-frequency transducer resulted in a theoretical evaluation which indicated that the transducer should be insensitive to a discrete set of frequencies. The analysis of the recorded data indicated that it is possible to have sound pressure levels at high frequencies (10 000–100 000 cps) in excess of the over-all sound pressure level normally measured from 20 to 10 000 cps.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
