MDHearing Aid® has announced a new hearing aid called Air. Fitting either ear, the AIR provides up to 45dB of gain, which is the measure of the ability of a hearing aid to increase the power of a signal, for mild, moderate or moderately-severe hearing loss. It has three separate programs and a telecoil (or t-coil) mode. AIR was created by Sreekant Cherukuri, M.D., a board-certified ear, nose and throat physician. It is being introduced at a price of  $350 for one or $600 for two.
