Getting the Best Fit Fast

Getting hearing instruments can be an emotional time for patients — some are excited, others feel anxious. And while a proper technical fit is essential, patients of every mindset want their fitting experience to focus on personal attention and advice. That’s where Sonic can help.

EXPRESSfit Fitting Software lets professionals take care of hearing aid adjustments quickly, and with remarkable accuracy. Not only does its aproach to fitting make the first fit process efficient, it helps minimize the need for future adjustments. Plus, the software’s simple and graphic interface streamlines the process. With EXPRESSfit, there’s less time spent at the keyboard, and more time discovering individual preferences, giving counsel, and answering questions.
