Paradoxically, measurements of the loudness of tinnitus indicate that the noise is not a very loud one, yet many persons experiencing it report severe distress. It has been suggested that either loudness has not been measured correctly or that some other factor such as recruitment may be involved.

Archives of Otolaryngology - Head and Neck Surgery, 1954
THE LOUDNESS growth in the normal ear adheres to a rather precise formula in conformity with the corresponding increase in intensity. At 1,000 cps a one to one ratio is obtainable between the sensation units of loudness and the decibels of intensity, while for all other cycles, the growth of loudness follows the equal loudness contour of Fletcher and ...

The American Journal of Psychology, 1973
The present study employed 600 subjects and extended earlier experiments under 'ideal' conditions to white noise. When known experimental biases were eliminated, half loudness was equal to half sound-pressure level (-6 dB) from 45 through 90 dB. The same simple relation held whether stimulation was through headphones or loudspeaker, and whether ...

Suprathreshold Loudness Adaptation
The Journal of the Acoustical Society of America, 1972Loudness adaptation at 500 Hz (70 dB SPL) was measured over a 7-min stimulation period using the tracking method. The duration of a simultaneous, contralaterally presented comparison stimulus (400 Hz) was either 250 or 3000 msec. Duty cycle of the two comparison stimuli was identical (3313%), however, use of the tracking method (8 dB/sec attenuation ...

Acta Oto-Laryngologica, 1986
Although tinnitus causes considerable suffering to many patients, its loudness is small in most cases. Traditionally the loudness is measured with a binaural loudness balance procedure. It is stated that when there is recruitment in the ear to which the test tone is presented, the intensity of the test tone is smaller than its loudness.

Individual differences in loudness processing and loudness scales.
Journal of Experimental Psychology: General, 1984Parameters of the psychophysical function for loudness (a 1000-Hz tone) were assessed for individual subjects in three experiments: (a) binaural loudness summation, (b) temporal loudness summation, and (c) judgments of loudness intervals. The loudness scales that underlay the additive binaural summation closely approximated S. S.

Diaphragm for loud speaker and loud speaker employing it
The Journal of the Acoustical Society of America, 2008The present invention provides a diaphragm for a loudspeaker which suppresses divided resonance and shows a stable sound-pressure-frequency characteristic, and a loudspeaker using the diaphragm. The diaphragm includes three or more thick parts (11 c) of odd numbers formed radially from a center part to an outer periphery, and semi thick part (11 d ...

Loudness changes induced by a proximal sound: Loudness enhancement, loudness recalibration, or both?
The Journal of the Acoustical Society of America, 2007The effect of a forward masker on the loudness of a target tone in close temporal proximity was investigated. Loudness matches between a target and a comparison tone at the same frequency were obtained for a wide range of target and masker levels. Contrary to the hypothesis by Scharf, Buus, and Nieder [J. Acoust. Soc. Am.

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 ...
