A hand-held mechanical applicator that delivers consistent insertion of standard foam earplugs, every patient, every technologist, every time. Earplug not included; use with standard tapered foam earplugs.

The Sert-A-Plug Earplug Insertion Tool delivers consistent insertion of standard foam earplugs through a standardized mechanical action that controls depth, angle, dwell, and compression release. A consistently, properly inserted plug seats better in the ear canal than one placed by hand, giving technologists a repeatable, documentable step for the hearing protection that scanner manufacturers require on every patient. In studies, consistent insertion raised the average measured fit (Personal Attenuation Rating) from 17.2 dB with naive self-insertion to 28.8 dB; on a logarithmic loudness scale, that can make a loud scan sound less than half as loud to the patient, which matters for comfort during long exams (Johnson & McCall, PAR study presented at NHCA 2026). Plug-agnostic and reusable, single-patient use in imaging settings per facility infection-control policy. Earplug not included; use with standard tapered foam earplugs. Winner of the 2023 Global Health Innovation Excellence Award from the Center for Advancing Innovation. Sert-A-Plug was also a Selected Idea in the 2016 'Hear and Now' Noise Safety Challenge, hosted by the U.S. Department of Labor (OSHA and the Mine Safety and Health Administration) and the National Institute for Occupational Safety and Health (NIOSH).

Frequently Asked Questions

1. How is Sert-A-Plug different from just handing a patient a foam earplug?

A foam earplug only performs as intended when it is inserted deeply and consistently, and hand insertion varies widely from one
person to the next, especially with a patient placing it themselves. Sert-A-Plug's mechanical action standardizes the insertion,
depth, angle, and compression release, so the same plug seats the same way every time. The plug still carries its own Noise
Reduction Rating; Sert-A-Plug is what gets that plug consistently and properly seated.

2. Does Sert-A-Plug make the scan more comfortable for the patient?

A consistent, properly seated fit is something the patient feels. In studies, consistent insertion raised the average measured fit from
17.2 to 28.8 dB PAR, and because loudness is perceived on a logarithmic scale, a fit improvement of that size can make a loud
scan sound less than half as loud to the patient. For a long, noisy exam, that difference in perceived loudness can make the
experience more tolerable (Johnson & McCall, NHCA 2026).

3. How does Sert-A-Plug fit into technologist workflow and documentation?

The tool adds a quick, repeatable insertion step a technologist can perform in seconds, and it works with the standard foam
earplugs a facility already stocks. Because the insertion is standardized rather than improvised, it gives the facility a consistent, documentable way to show that the hearing protection required by the scanner manufacturer was provided and properly fitted on each patient.

4. Which earplugs does it work with, and is the earplug included?

Sert-A-Plug is plug-agnostic and works with standard tapered foam earplugs from major suppliers. The earplug is not included with the tool, so facilities can continue using the foam plugs they already stock and trust. The plug carries its own Noise Reduction
Rating on the manufacturer's label; Sert-A-Plug delivers the consistent insertion of that plug.

5. Is Sert-A-Plug reusable, and how is it handled between patients?

The applicator is reusable by design. In imaging and healthcare settings it is used single-patient per the facility's own
infection-control policy. It is a simple mechanical tool with no electronics, sized to fit easily into an imaging workflow.
