CARL has a hearing loss!
"Test" CARL's hearing across a range of representative hearing losses and CARL will respond through the activation of LEDs. Create your own audiograms or use preloaded standardized audiograms in CARL.
in canal recordings made accessible
Microphones mounted at CARL’s eardrum allow for a fully representative ear canal while relying on the validated acoustics of CARL's existing ear anatomies. Output a simple high quality .wav file to simplify your setup.
Quantify and visualize the sound that is being delivered to CARL's eardrum. With CARL's full ear canal represented, measure sound level while deeply inserted devices or earplugs are fit in CARL's ears.
From our ongoing validation
We program CARL with specific audiograms and are asking students and instructors to test CARL's thresholds and to provide feedback on what they think of the simulator. Our early data looks very promising, with good agreement between the audiograms and the test results, and high ratings of CARL's usefulness as an Audiometry simulator. We plan to finish this work and share it with the field as soon as we can.Susan ScollieDirector, National Centre for Audiology, London, Canada
