Cell phones, computers and tablets have changed the way we see, hear, and connect with the world.

Unfortunately, people with hearing challenges have largely been shut millions out of this revolution...

We're all ears.


Sonitum has built transformative technology for personalizing audio for millions with moderate to profound hearing loss, from phone calls to videos and beyond.

We offer a cloud-based service that personalizes audio to telephony, hearing devices, streaming media, and, coming soon, television, and more.

For the first time, every phone call you make and every video you watch will be perfectly tuned to your hearing.
