What if your ears could blink?

Chameleon is adaptive hearing protection that reacts to the environment.

People often don't wear hearing protection when they need to communicate—taking hearing protection on and off is inefficient.

Chameleon is hearing protection that responds to the volume of the environment. When it's quiet, Chameleon allows you to hear as if you're not wearing hearing protection. When it's gets loud, it reacts in an instant to protect your hearing until the environment is safe again.

With Chameleon you'll never have to worry about missing important conversation on the job site. When it's quiet enough for conversation, you'll be able to hear all of it.

When it's quiet, Chameleon gets out of your way. When it's loud, Chameleon protects you. No more on and off of the hearing protection just to hear someone talk.

Keep it on for the whole day. Chameleon's custom foam pads allow less pressure on your head, making for a more comfortable headset.

Award winning team

We won both the Norman Esch competition for our pitch and demo, as well as the Systems Design People's Choice award.

Working prototype

We designed and built a working prototype using 3D printed components, a custom circuit board, and a Teensy microcontroller. The prototype successfully responds to loud noises, and attenuates until the environment is safe.

The working prototype presented at the engineering symposium.

Hands-on demo

We showcased our prototype at the Systems Design Symposium, and at the Norman Esch finals. Regular people who tried on our prototype could hear the difference in protection Chameleon offered, and were impressed with it's speed and the difference in noise level.

Tested in the Lab

With the help of Dr. Vanderkooy and Prof. Mann of the Audio Research Group at the University of Waterloo, we were able to test our prototype using a KEMAR acoustic mannequin. Results showed that our prototype provided a NRR of 18—enough to qualify for Class-B hearing protection.
