According to China's Audiology Network North America, reporting back to the latest technology, hearing aid industry, recently added a new breed of hearing aids: hearing aids within the mouth.  This sets a high-tech companies in Silicon Valley by the United States developed a very creative, very mysterious hearing aid is the United States conducting clinical trials, will soon be approved by the U.S. Food and Drug Administration certificate.

Even more interesting in the May 26, a former CIA investment company under, In-Q-Tel Inc. and gear transmission hearing aid research and development company, Sonitus established a strategic partnership investments.  The investment company has been investing in the high-tech, stealth technology and the value of a detective, said the partnership is no doubt to the future use of hearing aids transmission dental cast a mystery.
