Stanford University Evaluates the Efficacy of Threshold Sound Conditioning (TSC) as Possible Treatment for Sensorineural Hearing Loss.
Earlogic, Earlogic, a startup specializing in audio technologies, conducted a clinical study with Stanford University Hospital and the Palo Alto Medical Foundation to evaluate the efficacy of Threshold Sound Conditioning Technology.
The study shows that if there is a subtle damage in a particular frequency range, then listening to the customized minimally audible sound signals can protect that range from further hearing damage. Besides, the study demonstrated that over six out of ten people who used the technology for at least two weeks (twice a day for 30 minutes), showed an improvement of over 10 dB in their hearing capacity, while the rest has shown some improvements.
The positive effects of sound stimulation on hearing have been studied for several decades. In 1988, researchers at the Karolinska Institute in Sweden had shown that moderate sound stimulation reduces hearing loss caused by noise trauma. In 1999, research conducted at Harvard University found that utilizing sound conditioning over time, by listening to a particular sound frequency improves the sensitivity of the cochlea (the auditory portion of the inner ear).
Earlogic Research Institute demonstrated the effectiveness of sound conditioning for hearing enhancement. The Institute has developed a technology that allows people to recover up to 10 dB within two weeks and thereby improves related symptoms caused by hearing loss, such as tinnitus.
The good news is that the vast majority of hearing loss cases are related to damaged hair cells that have not been broken off, causing them to die out. Other technological tools developed with Earlogic technology include medical and diagnostic devices/software for hearing specific treatments.
Conclusions from Earlogic Research Institute prove that the Threshold Sound Conditioning Technology improves hearing by more than 10 dB. (“Customized sound stimulation improves pure-tone hearing threshold.” Sangyeop Kwak and Eunyee Kwak, 34th ARO meeting, FEB 19~23, 2011, Baltimore, Maryland, USA).
Moreover, institutes such as Samsung Medical Center, Chung Ang University, and U.S. National Institutes of Health have all researched and approved the efficiency of our technology. Stanford University has recently concluded the study, with positive results and was published in a leading neurology journal, in April 2015.
