Speech intelligibility is key for effective communication. Factors that affect speech intelligibility, include background noise level, distance away from the speaker, acoustics of the environment and reverberation.
In situations where these factors affect the signal-to-noise ratio (SNR), understanding speech can still be challenging. Hearing aids provide the most benefit when a speaker is within 1.5 meters/5 feet of the listener. As soon as the noise increases and the distance between the listener and speaker becomes greater, additional technology is needed to maintain speech intelligibility and understanding while overcoming both distance and noise.
Hearing in noise
This is where Roger comes in to boost hearing aid performance. Roger microphones have been developed to reduce background noise and transmit the speaker’s voice directly to hearing aids or cochlear implant sound processors. This enables your clients to fully participate in group conversations even in very noisy environments such as restaurants, meetings at work and school activities.
