The aim of this work is to present problems related to tinnitus symptoms, its pathogenesis, hypothe-
ses on tinnitus causes, and therapy treatment to reduce or mask the phantom noise. In addition, the
hypothesis on the existence of parasitic quantization that accompanies hearing loss has been recalled.
Moreover, the paper describes a study carried out by the Authors with the application of high-frequency
dither having specially formed spectral characteristics. Discussion on preliminary results obtained and
conclusions are also contained.
Keywords: tinnitus; sensorineural hearing loss; tinnitus masking; Tinnitus Retraining Therapy (TRT); signal quantization; dithering technique; high-frequency linearization; ultrasound dither noise
