Frequently Asked Questions

Traditional hearing aids mostly adjust volume and pitch. Fortell separates voices from background noise first, then boosts what you want to hear.

To break it down:

• What do most hearing aids do? They treat everything as one blended sound and try to “filter” it by turning volume and pitch up or down.
• Why doesn't that work well in real life? Voices and noise overlap–so speech still gets lost in restaurants, cafés, and group conversations.
• What does Fortell do instead? Fortell splits sound into two streams in real time: voices and background noise.
• What does that feel like for you? In noisy places, the background noise is dampened so you can focus on the person in front of you.
• How does it happen without an awkward delay? Fortell runs that spatial AI model directly on a custom on-device chip so your hearing aid can process sound in real time without “lag,” which matters because even tiny delays can feel unnatural in conversation.
