Resumen
Tinnitus is an irritating sensation of hearing a sound when no external sound is present, even interfering with the quality of life of its patients. Its increasing and high prevalence has reached millions of people. Fractal sounds are musical nuances with combined and semi-predictable connections, generated by recursive procedures.This study presents a possible alternative treatment through the use of fractal sound, without sound amplification, in the relief of tinnitus. The study included 32 individuals, of both genders, different ages, complaining of tinnitus, with sensorineural hearing loss, up to 60dB. The research participant performed anamnesis, meatoscopy, pure tone audiometry, logoaudiometry, immittanciometry, acuphenometry and answered the questionnaire Tinnitus Handicap Inventory – THI and numerical scale at the beginning and at the end of the study. The fractal sound was heard through the participants’ own cell phones, with headphones provided by the cell phone manufacturer, for three months, for one hour daily. The type of tinnitus found was high pitch, with an average of 5673.5 Hz. According to THI, in relation to tinnitus severity, it was observed that participants who started the study in the severe classification, 75% concluded the study as mild and slight disadvantage and 25% as moderate deficiency. The THI showed a significant difference in the functional scale, emotional scale, catastrophic scale and also in the final total score of the questionnaire. There was a statistically significant difference in the initial and final averages of the numerical scale, in the level of awareness and in the level of discomfort with tinnitus. The research participants reported tinnitus relief by listening to fractal sound without sound amplification through their own cell phones. With the results achieved it is acceptable to conclude that fractal sound without sound amplification is effective in relieving tinnitus.
