Cleanhearing Sono technology is based on years of clinical research into the effects of pulsed electromagnetic stimulation on tinnitus and related conditions.

This large body of research shows that pulsed electromagnetic stimulation is significantly more effective in relieving tinnitus than sham treatments with no adverse events observed.  It also demonstrates PEMFs effectiveness for many conditions linked to tinnitus, such as chronic pain, depression and insomnia, and identifies underlying biological mechanisms of PEMF.

PEMFs positive effects have been observed at the very safe, weak magnetic field strengths applied by Cleanhearing Sono, as well as the stronger magnetic fields used in clinic-based applications such as rTMS.

Notched music, which you can access via the Cleanhearing app, is also shown by clinical trials to be beneficial and safe for a subset of tinnitus patients with a pure-tone tinnitus.
