Acoustical Characteristics of Tinnitus: An Analysis

The relationship between tinnitus pitch and the edge frequency of the audiogram in individuals with hearing impairment and tonal tinnitus

“…The matching SLs were relatively low, ranging from 7.1 to 18.9 dB. This is consistent with previous work (Fowler, 1941;Graham and Newby, 1962;Reed, 1960;Vernon, 1976;Tyler and Conrad-Armes, 1983). The low SLs do not necessarily imply that the tinnitus was heard as very quiet, since the subjects probably experienced loudness recruitment at the matching frequency (Tyler and Conrad-Armes, 1983;Penner, 1986;Cope et al, submitted for publication); a low SL does not imply a soft percept in an ear with recruitment .…”

A Bayesian Perspective on Tinnitus Pitch Matching

“…All Meniere’s subjects had pitch matches below 1000 Hz (median 320 Hz), which agreed with findings of Walsh (1956), Caparosa (1963), and Day (1963). The conductive hearing loss group had a median pitch match of 490 Hz (range 90–1450 Hz), which differed significantly from the sensorineural group (median 3900 Hz, range 545–7500 Hz) in agreement with the findings of Graham and Newby (1962).…”

Psychoacoustic Measures of Tinnitus

“…14-3 and 14-5 in Meikle, 1995). This was also seen earlier by Graham and Newby (1962) . It is clear that pitch matches for tinnitus can occur practically anywhere in frequency regions where there is hearing loss .…”

“…All Meniere's subjects had pitch matches below 1000 Hz (median 320 Hz), which agreed with the findings of Walsh (1956), Caprosa (1963), and Day (1963) . The conductive hearing loss group had a median pitch match of 490 Hz (range = 90-1450 Hz), which differed significantly from the sensorineural group (median = 3900 Hz, range = 545-7500 Hz), in agreement with the findings of Graham and Newby (1962) . Douek and Reid (1968) attempted to determine if a clinical audiometer could be used to obtain pitch matches that had diagnostic value.…”

“…Loudness Matching at the Tinnitus Frequency versus at a Normal-Hearing Frequency Vernon (1976) noted the previous findings of Reed (1960), Fowler (1942), and Graham and Newby (1962) showing that tinnitus was typically matched to tones only a few decibels above threshold. The question was how tinnitus of "such feeble intensities" could be so disturbing.…”
