Sound Enrichment Therapy

Sound enrichment therapy refers to the deliberate introduction of background sound into a person's listening environment to reduce the perceived contrast between silence and tinnitus, particularly during periods when tinnitus is most noticeable, such as at night or in quiet environments. The rationale is straightforward: tinnitus tends to be most prominent when the surrounding acoustic environment is very quiet, because there is little external sound to compete with the internally generated tinnitus signal.

Common forms of sound enrichment include tabletop sound machines, smartphone apps producing nature sounds (rain, ocean waves, flowing water), broadband noise (white or pink noise), soft music, or low-level radio. The sound level used is typically set slightly below the tinnitus, so that the tinnitus is not fully masked but is made less prominent. Full masking (covering the tinnitus entirely) is generally not the goal in habituation-based tinnitus therapy, as it may interfere with the habituation process.

Sound enrichment is accessible and low-cost, making it a practical first-step recommendation for many people with tinnitus. It does not treat the underlying cause of tinnitus but can significantly improve sleep quality and reduce the distress associated with sitting in silence. It is frequently recommended by audiologists as part of a broader tinnitus management plan alongside counseling, cognitive strategies, and, where appropriate, hearing aids.
