Binaural Directionality III

The Clear Sound Experience

When we hear naturally, the ears collects sound from all around you and your brain decides what to listen to. Unfortunately, most hearing aids attempt to block out sounds from the side and back completely. This unnatural way of hearing makes it difficult to recognize where sounds are coming from or switch your focus to other important sounds.   

But, with Binaural Directionality III we make it easier by using ear-to-ear technology. This allows your hearing aids to work together to more accurately mimic how our ears naturally take cues from each other to fill in the entire sound scene. The result is even better awareness of environmental sounds and where they are coming from.

Better Ear/Situational Awareness Metric (BESA)

The balance between the sounds we hear in front of us and those from the sides and back is important to our ability to understand speech, where sounds are coming from, and to monitor any sounds around us, if we need to quickly shift focus. This metric is based on a model of binaural hearing, and quantifies how the combination of microphone responses on each ear allow for improved signal-to-noise ratio (Better Ear Effect) and audibility of surrounding sounds (Situational Awareness). The normal, unaided ear serves as the reference for this model, and was carefully considered in the design of the directional system for ReSound LiNX 3D™.

Chart explanation: Results of the BESA metric for various directional hearing aid solutions on the market clearly show that ReSound LiNX 3D combines hearing sounds from the front, sides and back the closest to the unaided ear, for the most natural hearing experience.
