Loudness functions with air and bone conduction stimulation in normal-hearing subjects using a categorical loudness scaling procedure.
In a previous study (Stenfelt and Håkansson, 2002) a loudness balance test between bone conducted (BC) sound and air conducted (AC) sound was performed at frequencies between 0.25 and 4 kHz and at levels corresponding to 30-80 dB HL. The main outcome of that study was that for maintaining equal loudness, the level increase of sound with BC stimulation was less than that of AC stimulation with a...
متن کاملReliability of categorical loudness scaling and its relation to threshold.
OBJECTIVE To further examine the reliability of categorical loudness scaling (CLS) for individual loudness categories and for the slope of the CLS functions. And, to evaluate the relationship between CLS and audiometric threshold. DESIGN CLS functions were obtained in 74 subjects, 58 with hearing loss and 16 with normal hearing. CLS functions were measured at three frequencies (1, 2, and 4 kH...
متن کاملLoudness scaling revisited.
The present work was undertaken in an attempt to evaluate whether it is reasonable to expect that categorical loudness scaling can provide useful information for nonlinear hearing aid fitting. Normative data from seven scaling procedures show that the individual procedures relate the perceptual categories differently to sound level and with a substantial between-subject variance. Hearing-impair...
متن کاملMeasuring tinnitus loudness using constrained psychophysical scaling.
PURPOSE We measured tinnitus loudness using a new method of psychophysical scaling with the aim of introducing a potentially useful new procedure to the literature. METHOD Fourteen adults reporting tinnitus were trained to use a standardized loudness scale, and then they used that response scale to assess loudness of nonstandard stimuli and of their tinnitus. We also measured tinnitus loudnes...
متن کاملLoudness Scaling in a Digital Synthesis Library
The paper describes the algorithms used in MOSS, an additive synthesis library, to realize sounds with a prescribed loudness. Loudness is a perceived attribute of sound that depends both on the amount of energy carried by the sound wave and on the way this energy is processed by the ear-brain system. The loudness routines in MOSS translate the target loudness of a sound into amplitudes of the c...
