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