A new method for measuring the psychoacoustical properties of tinnitus.

Kostek B, Poremski T - Diagn Pathol (2013)

Bottom Line: For this purpose the multimedia-based sound synthesizer has been proposed for testing tinnitus and the results obtained this way are compared with the outcome of the audiometer-based Wilcoxon test.Moreover, they do not concentrate on describing verbally their tinnitus, which could be difficult for some of them.As a result, the test outcome is closer to the perceived tinnitus.

ABSTRACT

Background: This study investigates the usefulness and effectiveness of a new way of tinnitus screening and diagnosing. The authors believe that in order to arrive at relevant diagnostic information, select the tinnitus treatment and quantitatively substantiate its effects, the measurement of the Tinnitus psychoacoustic parameters should be made an inherent part of the Tinnitus therapy.

Methods: For this purpose the multimedia-based sound synthesizer has been proposed for testing tinnitus and the results obtained this way are compared with the outcome of the audiometer-based Wilcoxon test. The method has been verified with 14 patients suffering from tinnitus.

Results: The experiments reveal capabilities, limitations, advantages and disadvantages of both methods. The synthesizer enables the patient to estimate his/her tinnitus more than twice as fast as the audiometer and makes the information on the tinnitus character perception more accurate. The analysis of the Wilcoxon test results shows that there are statistically important differences between the two tests.

Conclusions: Patients using the synthesizer operate the software application themselves and thus get more involved in testing. Moreover, they do not concentrate on describing verbally their tinnitus, which could be difficult for some of them. As a result, the test outcome is closer to the perceived tinnitus. However, the more complex the description of the perceived tinnitus, the harder it is to determine the sound parameters of the patient's perception. It also takes more time regardless of the method.

Figure 1: The user interface for Tinnitus sound synthesis.

Mentions: The central element of Tinnitus synthesizer interface is a rectangular color space with axes marked at the bottom and on left side (Figure 1). The lower axis represents frequency of sound, while the vertical axis represents amplitude of sound. Amplitude as a function of frequency, i.e. amplitude spectrum is displayed in the window. There are three icons located on the right side of the panel. Each icon represents a different type of sound: a simple tone, white noise, sound. The user can select an icon and drag it to the above-described area. Moving icons horizontally will change sound frequency, while the vertical movement changes its amplitude. The designated area is assigned to each frequency band of different colors: cool colors to low frequencies, and warmer colors to higher frequencies. The color intensity represents the amplitude of sound (intensity)–the higher the sound level, the greater the intensity of color (more saturated). In case of simple tones the user modifies their frequency, whereas in the case of noise the user can adjust the frequency band to which the sound is limited in the frequency domain.
