Digital Hearing Aid and Threshold Sound Conditioning

TSC-i48 Hearing Aid

Based on the principles of Threshold Sound Conditioning, the TSC-i48 is the FIRST product in the world that combines the functionality of the traditional hearing aid with an innovative feature to reverse hearing loss. This industry-changing product actually treats hearing loss in its most fundamental levels.

- The first non-invasive, non-drug therapy to improve age-related and noise-induced hearing loss

- Possibility of significant hearing improvement effect by using Threshold Sound Conditioning (TSC)

- Currently used as the test device for TSC clinical trials with the Stanford University School of Medicine
