Amplitude and Loudness: A Scaling Problem
Abstract
The article discusses the relationship of the decibel scale to good scaling procedures. It points out the initial utility of such a scale for problems such as power loss in transmission lines. However, the point is made that when the decibel is used for purposes related to such variables as hearing loss and annoyance the scale properties of the decibel change due to the nature of the underlying variable. Certain problems exist when the decibel is used without taking into account the nature of these changes. Some implications of the power law relationship between sound and psychophysiological variables are discussed.
