Reliability 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 کاملThe contour test of loudness perception.
OBJECTIVE This article presents the underlying rationale, normative data, and reliability data for a test of loudness perception (the Contour Test) that was devised for use in clinical hearing aid fitting. The Contour Test yields data describing the sound level required for each of seven categories of loudness ranging from very soft to uncomfortably loud. DESIGN Two experiments are described....
متن کاملLoudness 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 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 کاملNoise evaluation based on loudness-perception characteristics of older adults
The frequency-weighting A used for noise measurement was determined based on hearing characteristics expressed as equal-loudness-level contours. The time-averaged, A-weighted sound level (LAeq) of a sound corresponds well with the perceived loudness. However, good correspondence between LAeq and the perceived loudness is confined to cases in which listeners are young people with normal hearing....
