Threshold Sound Conditioning™

Threshold Sound Conditioning™ (TSC) was officially adopted for the first time by Stanford University in 2012. TSC has shown a significant effect on hearing sensitivity improvement with clinically proved evidence.

Sound Vaccine™

The spiral template of Sound Vaccine™ produces each of 31 sweep tones. Each of 7 layers of 10 dB step TSC level is calibrated in accordance with 0 dBHL reference values of ISO226:2003 as a function of frequency. 

RPR Effects by TSC

An RPR means the retardation, prevention, and restoration from any subtle damages in the hearing threshold micro structure. The experience of RPR effects is available to registered members only.
