The Contour Test of loudness perception yields data describing the sound level required for each of seven categories of loudness ranging from very soft to uncomfortably loud. It was designed to be used in clinical hearing aid fitting. Evidence from research indicates that standardized measurement of loudness perception is an achievable goal for clinical practice. The Contour Test offers a viable approach to clinical measurement of loudness perception. It has good patient acceptance and combines fairly rapid administration with acceptable reliability.
