The influence of tinnitus frequency on patients experiencing subjective tinnitus and the efficacy and prognosis of acoustic therapy.

Objective: This study examines the therapeutic impact and prognosis of acoustic therapy in patients with chronic subjective tinnitus across different tinnitus frequencies.

Methods: A total of 135 patients with subjective tinnitus were selected and categorized based on their primary tone frequency into three groups: high frequency (43 patients, 4-8 kHz), mid frequency (40 patients, 1-3 kHz), and low frequency (42 patients, < 1 kHz). All patients received acoustic therapy customized to their specific frequency and loudness levels, along with tinnitus cognitive behavioral therapy.

Clinical efficacy of cognitive behavioral therapy for chronic subjective tinnitus.

Background: Although cognitive behavioral therapy (CBT) has been known with a theoretical basis for tinnitus patients, there still were lack of clinical evidence.

Objective: To evaluate the clinical efficacy of cognitive behavioral therapy (CBT) for treatment of chronic subjective tinnitus.

Methods: One hundred patients with chronic subjective tinnitus patients were randomly divided into control (50 cases) and intervention (50 cases) groups, which received the masking therapy and sound treatment and masking therapy and sound treatment plus CBT.
