[Multivariate analyses using quantitative method II of annoyance due to tinnitus].
Factors affecting annoyance due to tinnitus were analyzed using quantitative method II. Ninety-one patients with unilateral tinnitus of single kind were studied. Major factors affecting annoyance due to tinnitus were found to be subjective loudness of tinnitus, age, degree of hearing loss, tinnitus loudness level in dB HL, pitch matched frequency, puerility and impurity of tinnitus tonality, and subjective tinnitus pitch. Increased annoyance due to tinnitus was associated with an age of 30-49 years, a tinnitus loudness level between 25 and 49 dB HL, a tinnitus loudness level more than 15dB SL, impurity of tinnitus tonality, larger subjective loudness, and high-pitched tones above 4000Hz. Decreased annoyance due to tinnitus was related to the smaller subjective loudness, loudness level below 25dB HL, low-pitched tones below 250Hz, and purity of tinnitus tonality. Our results suggest that these factors are responsible for individual differences in annoyance caused by tinnitus.
