Table 1.
Variables are expressed as means and standard deviations (SD). 4FA = pure tone average of the ear with tinnitus or more severe tinnitus if bilateral, PTAhf = pure tone average high frequencies, Pitch = frequency match between tinnitus and pure tone expressed in kHz, SLL (subjective loudness level) expressed in dB, THI total score and its subscales. Independent T-Test: p < 0.005 = (**); df = degree of freedom.
