Oticon Opn significantly reduces listening effort
New research shows a significant increase in listening effort for people with hearing loss, even when noise is quieter than speech.
Testing people’s ability to understand speech in noisy environments has become somewhat of a benchmark in hearing research. But when it comes to understanding how people with hearing loss handle typical daily listening situations, simple speech-in-noise testing is not enough*.
With the speed and precision of Multiple Speaker Access Technology (MSAT), the OpenSound Navigator can reduce noise enough to significantly reduce listening effort in everyday listening environments, while at the same time delivering an open sound experience.
OpenSound Navigator significantly narrows the gap between hearing loss and normal hearing in everyday listening environments. Consequently, across different listening environments Oticon Opn 1 will provide the most support.****
