KELTRON SHRAVAN Behind the Ear 110-HT and KELTRON SHRAVAN Behind the ear 110-LT are feature rich state-of-the-art Digital Programmable Hearing Aids which use sophisticated Digital Signal Processing (DSP) techniques, based on the indigenously developed Application Specific Integrated Circuit (ASIC) named NAADA, offering superior and stable characteristics over a wide dynamic range. Frequency-dependent filtering and built-in fitting formulae help in the fine reproduction of the hearing rest results and accurate prediction of optimum amplification. This, in turn, allows unparalleled sound quality, ease and reliability in ear- specific customization.

Working on a single, easily available zinc-air battery, SHRAVAN Hearing aids have low cost of ownership and maintenance.
