Measurement of Individual Loudness Functions by Trisection of Loudness Ranges
Ear & Hearing, 2008Loudness-balance measurements with monaurally impaired subjects have shown that the shape of the loudness versus sound-pressure curve among hearing-impaired persons varies significantly. But the effectiveness of adjusting the compression characteristics of wide-dynamic-range compression hearing aids-the compression ratios, the variation of compression ...

The Loudness and Loudness Matching of Short Tones
The Journal of the Acoustical Society of America, 1949A monaural loudness matching technique was used to study differential sensitivity to intensity as a function of tonal duration. The probable error (p.e.) of the loudness matches was used as the measure of differential sensitivity. With one technique, a standard tone of 500 milliseconds duration was followed by a tone of variable duration (10–500 ...

Obstetrical & Gynecological Survey, 1993
Whether loud noise is harmful to the developing fetus and warrants removal of the pregnant woman from exposure remains ambiguous. The role of noise attenuation in utero in determining risk is discussed in this review. Reports in the medical literature have been frequently found to have confounders for human fetal development.

Loudness of ramped and damped sounds: comparison of global loudness and loudness change
2010Loudness change has been recently studied for tones with linearly varying levels. The published results by di erent authors revealed an asymmetry in the judgment of loudness change for increasing and decreasing levels depending on the range of level. But the results and their interpretations were di erent between Canévet's and Neuho 's studies.

The Journal of the Acoustical Society of America, 1955
This paper reviews the available evidence (published and unpublished) on the relation between loudness and stimulus intensity. The evidence suggests that for the typical listener the loudness L of a 1000-cycle tone can be approximated by a power function of intensity I, of which the exponent is log102. The equation is: L = kI0.3.

On the Matching of “Loudness.”
The Journal of the Acoustical Society of America, 1961A series of experiments examined the reliability of the method of adjustment, or loudness matching, as a means of measuring the subjective intensity of audio signals. The common procedure requires the observer to set the intensity of a “standard” 1000-cps tone of fixed duration to equality with the loudness of another signal.
