Digital Frequency Customized Relieving Sound for Chronic Subjective Tinnitus Management: Prospective Controlled Study

Area of Science:

• Otolaryngology
• Digital Health
• Acoustic Therapy

Background:

• Chronic subjective tinnitus lacks effective elimination treatments.
• Acoustic therapy, particularly personalized approaches, is crucial for tinnitus management.
• Smartphone integration enhances personalized acoustic stimulation for individualized tinnitus care.

Purpose of the Study:

• To evaluate the efficacy of Digital Frequency Customized Relieving Sound (DFCRS) for tinnitus treatment.
• To explore factors influencing the therapeutic effects of DFCRS.

Main Methods:

• A nonrandomized trial compared personalized DFCRS via an app (107 participants) with unmodified music (UM) (77 participants).
• Participants used DFCRS or UM for at least 2 hours daily over 3 months.
• Multidimensional scales (THI, HADS, AIS, FTQ, TCS) assessed tinnitus severity and quality of life.

Main Results:

• DFCRS significantly reduced tinnitus severity (THI scores) compared to UM (P<.001).
• 92.5% of DFCRS users reported relief; longer daily treatment correlated with better outcomes (P=.007).
• Baseline tinnitus severity and treatment duration predicted better response.

Conclusions:

• DFCRS is a promising, noninvasive therapy for chronic tinnitus.
• Mobile app delivery of DFCRS offers convenience for patients.
• Personalized acoustic therapy via apps can improve tinnitus management.
