Environmental Impact - Sound

Wurzbach, W. F., & Freund, M. (1975). Portrait in sound: A study comparing ambient sounds with those generated by snowmobiles.

Abstract

This study is a very technical approach to increasing the awareness of the noise environment in which we find ourselves and its impact upon our daily lives, both physically and subjectively. This study concluded that snowmobile noise is a noise source contributor but not a major contributor.

Presents a method for predicting the impact of noise on outdoor recreation called the System for the Prediction of Acoustic Detectability (SPREAD). SPREAD attempts to address the phenomenon of detectable noise vs. measured ambient noise levels with a formula (and worksheets) for predicting sound levels for the purpose of deciding what is appropriate/inappropriate acoustic impact in recreation sites.
