Outcome Measures

Primary Outcomes (5)

  • Change from Baseline in Tinnitus Subjective Measures at 12 weeks: pure tone audiometry

    baseline and 12 weeks

  • Change from Baseline in Tinnitus Subjective Measures at 12 weeks: tinnitus loudness

    baseline and 12 weeks

  • Change from Baseline in Tinnitus Subjective Measures at 12 weeks: minimize masking level

    baseline and 12 weeks

  • Change from Baseline in Tinnitus Subjective Measures at 12 weeks: the Chinese version of Tinnitus Handicap Inventory scale

    baseline and 12 weeks

  • Change from Baseline in Tinnitus Subjective Measures at 12 weeks: the Visual Analog Scale

    baseline and 12 weeks

Secondary Outcomes (1)

  • Change from Baseline in Tinnitus Objective Measure at 12 weeks: functional magnetic resonance imaging (fMRI)

    baseline and 12 weeks

Study Arms (2)

masking therapy

ACTIVE COMPARATOR

Masking intervention was a standard monophone tinnitus masking therapy.

Device: masking therapy

CAABT

EXPERIMENTAL

CAABT was an innovative tinnitus intervention which based on neural science and cochlear plastic research and aimed to reprogram the central auditory system to neutralize the discordant responses of the dysfunctioning cochlea via acoustic beaming stimuli.
