3M 7000127216 Clear Silicone Ear Canal Training Model

Product Description

The 3M 7000127216 is a clear silicone rubber replica of the human external ear and ear canal, designed as a hands-on training aid for proper insertion of in-ear hearing protectors. Molded to replicate the anatomic features of the ear canal, this model allows trainers and safety professionals to demonstrate correct earplug fit and positioning. The transparent construction gives a full view of outer ear structures from multiple angles, including outside-in and inside-out perspectives from the top, bottom, front, and back. It is used in occupational safety training programs where correct hearing protector insertion technique is critical to achieving rated attenuation.

This model is suited for use in industrial safety training, hearing conservation programs, and occupational health settings. Safety managers, industrial hygienists, and hearing conservation program administrators use this replica to demonstrate proper earplug fit to workers before initial use and during refresher training. Its clear silicone construction makes it especially effective in group training sessions where visualization from multiple viewing angles is needed to convey correct insertion depth and canal fit.
