Specialty Solutions: Single-Sided Hearing and Challenging Noise

Not every type of hearing loss affects both ears equally. For patients who hear well on one side but experience little or no hearing on the other, traditional hearing aids can fall short. That’s where CROS (Contralateral Routing of Signal) systems come in—a breakthrough designed specifically for single-sided hearing loss.

CROS systems use a clever wireless setup: one device captures sound from the weaker ear and sends it to a hearing aid on the better-hearing side. The result is balanced, natural listening and restored spatial awareness, even in noisy settings.

How Modern CROS Systems Work

• Wireless Transmission: Tiny transmitters send sound seamlessly from one ear to the other with no delay or distortion.

• AI-Powered Directionality: Newer CROS models use artificial intelligence to identify and prioritize speech, even when it comes from the weaker side.

• Improved Speech Recognition: Voices remain clear across crowded spaces—ideal for restaurants, meetings, or family gatherings.

• Comfort and Fit: Ultra-light designs ensure comfort throughout the day without pressure or feedback issues.

CROS technology has become an empowering option for patients once told “nothing can be done” for single-sided loss. Paired with AI sound processing, it creates an almost seamless hearing experience.

Learn more about how CROS hearing aids work.

When CROS Isn’t Enough

For some, advanced BiCROS systems are recommended. These not only transmit sound but also amplify it in the better ear—perfect for users who have some degree of hearing loss on both sides.

AI enhancement now makes BiCROS systems even more effective by automatically distinguishing speech from noise and reducing the cognitive effort needed to follow conversations. Whether you’re listening to coworkers in a meeting or catching every word from a loved one across the room, these systems restore the sense of balance and direction that makes conversation feel natural again.
