Listening to tailor-made notched music reduces tinnitus loudness and tinnitus-related auditory cortex activity.

Maladaptive auditory cortex reorganization may contribute to the generation and maintenance of tinnitus. Because cortical organization can be modified by behavioral training, we attempted to reduce tinnitus loudness by exposing chronic tinnitus patients to self-chosen, enjoyable music, which was modified ("notched") to contain no energy in the frequency range surrounding the individual tinnitus frequency. After 12 months of regular listening, the target patient group (n = 8) showed significantly reduced subjective tinnitus loudness and concomitantly exhibited reduced evoked activity in auditory cortex areas corresponding to the tinnitus frequency compared to patients who had received an analogous placebo notched music treatment (n = 8). These findings indicate that tinnitus loudness can be significantly diminished by an enjoyable, low-cost, custom-tailored notched music treatment, potentially via reversing maladaptive auditory cortex reorganization.
Listening to Filtered Music as a Treatment Option for Tinnitus: A Review.
Music Percept. 2010 Apr 1;27(4):327-330. Wilson EC, Schlaug G, Pantev C.
TINNITUS IS THE PERCEPTION OF A SOUND IN THE absence of an external acoustic stimulus and it affects roughly 10-15% of the population. This review will discuss the different types oftinnitus and the current research on the underlying neural substrates of subjective tinnitus. Specific focus will be paid to the plasticity of the auditory cortex, the inputs from non-auditory centers in the central nervous system and how these are affected by tinnitus. We also will discuss several therapies that utilize music as a treatment for tinnitus and highlight a novel method that filters out the tinnitus frequency from the music, leveraging the plasticity in the auditory cortex as a means of reducing the impact of tinnitus.
