Influences Of Wind On Automotive Interior Sound Quality, Sara Huelsman, Patricia Davies, Daniel Carr
The Summer Undergraduate Research Fellowship (SURF) Symposium
The effects of noise on human health (both mental and physical) are well known, and motivation to decrease noise in daily life is prevalent. Wind noise within automotive interior cabins could be detrimental to human health and comfort because of the negative impact on speech intelligibility and fatigue overall. There is little information on human perception of wind noise in automobile interiors though Loudness and Articulation Index have been examined as predictors of human response. They have been found to predict well in some circumstances, but not in others. In this research, a variety of sound quality metrics are being …

Cord Load Characteristics In Bias And Belted-Bias Tires, Joseph Walter, George Hall
Dr. Joseph D. Walter
Two improved versions of a recently developed miniature force transducer were used to measure cord loads at the crown, shoulder, and sidewall of bias and belted-bias automobile tires under different testing conditions. As a transducer at a given location passes through the footprint, a “basic shape” for the cord force pattern is generated for straight ahead rolling and cornering. Factors such as wheel load, inflation pressure, obstacle impact, tire speed, rim width, and frictional properties of the tire-drum interface can affect the total force excursion and/or the base line value but do not affect the basic shape of the patterns. …
