Binaural listening is more accurate in sound source positioning, improves speech resolution in noise, improves clarity, eliminates head shadow effects, and adds up to increase overall loudness and improve sound quality. Improved resolution and intelligibility can also prevent a phenomenon in audiology called “auditory deprivation” and avoid further deterioration of disused auditory functions.If one ear is almost completely deaf, it is recommended to wear one ear or use CROS hearing aids.In short, the opinion of the fitter is very important.In general, both ears need to be worn.
