CARL and AHead Simulations were created in 2015-2018 to solve a problem with education of new clinicians - to improve the safety and quality of training within hearing healthcare. Upon use in these settings, CARL has continued to drive value across several different aspects of the industry such as clinical training, clinical research, and patient consultations.

The CARL simulators have been developed based on years of research at Western University and the National Centre for Audiology. Through rapid prototyping and lean manufacturing, CARL continues to improve every day. CARL’s ears have been fine-tuned for material properties and acoustical properties for over 4 years, and the CARL manikins and Camera CARL have been active in continuous improvement throughout manufacturing.

The CARL training system represents a platform in which you can realize the advantage to experiential learning and the ease of having a ‘perfect patient’ on hand at all times.

We hope you enjoy your CARL system as much as we have enjoyed making it.

Cheers,
AHead Simulations Team.

CARL is your perfect patient. Our varying options are packaged to suit the needs and goals different professionals have in varying environments.

Realism
Replicating the anatomy and acoustics of a human volunteer for any of your uses. CARL is your perfect patient for any training, research, or demonstration environment in which you need a patient-realistic model with head, shoulders, and ears.

Lightweight yet Durable
Built to withstand travelling and extended use, as well as hosting a variety of mounting options for optimal set up in your environment. CARL is tested to be classroom/student safe, and capable of travelling around the world.

Simulation Made Simple
CARL is designed to simulate your patient, not your equipment. Use any equipment from any manufacturer, any device, any technique on CARL. No complicated set up or programming - unbox him and you’re ready to go!

Modular/Expandable
CARL is made to be as modular as possible to support in-head feedback systems (see CameraCARL) and a wide array of ear anatomies available.

An Inside View
With Camera CARL, receive a video feed inside of CARL's ear canal for viewing objects, equipment, and anything else that happens to find its way inside CARL’s canal!

Performance Metrics
Utilizing CARL allows you to see locations of object's inside of CARL's ear canal. Track clinician performance and run tests to evaluate competency. How far from the eardrum is my probe?

Realism
Replicating the anatomy and acoustics of a human volunteer for any of your uses. CARL is your perfect patient for any training, research, or demonstration environment in which you need a patient-realistic model with head, shoulders, and ears

Lightweight yet Durable
Built to withstand travelling and extended use, as well as hosting a variety of mounting options for optimal set up in your environment. CARL is tested to be classroom/student safe, and capable of travelling around the world.

Realism for Pediatrics
Replicating the anatomy and acoustics of a pediatric volunteer for any of your uses and encountering pediatric-specific challenges such as smaller sizes, smaller room to work.

Lightweight yet Durable
Built to withstand travelling and extended use, as well as hosting a variety of mounting options for optimal set up in your environment. Baby-CARL is tested to be classroom/student safe, and capable of travelling around the world.

Simulation Made Simple
Baby-CARL is designed to simulate your pediatric patient, not your equipment. Use any equipment from any manufacturer, any device, any technique on Baby-CARL. No complicated set up or programming - unbox him and you’re ready to go!

Modular/Expandable
Baby-CARL is engineered to be modular so any future update or future anatomical options are available as an add-on to your current Baby-CARL system.

Anatomical Realism

Developed directly from clinical CT scans to represent patient-specific anatomies with over 5 years of fine-tuning and optimization to find the best material properties for your use. CARL Ears are the closest to patients that you can get in the world.

Acoustic Realism

Acoustics have been fine-tuned to provide a clinically relevant response for the fitting and testing of hearing aids. Acoustics are replicated through effective material selection and the use of a full-ear canal to the eardrum. (see full acoustic measurements below)

Built to Last
Ears have been tested in a variety of environments along with industry-leading suppliers of reliable material characteristics. Can withstand even the most inexperienced clinicians!

Variety of Options for Your Use Case
With your CARL ear anatomies, you have a choice of anatomy, skin tone, and opaque vs transparent ear canal options (seen below)
