## Description

Sert-A-Plug develops tools designed to improve the fit and consistency of foam earplugs for occupational hearing protection. Its disposable earplug fitting applicator uses patented Cert-A-Fit technology to guide a standardized mechanical insertion, helping make earplug fitting simpler and faster for workers and hearing-care professionals. The company’s focus is on fit, an important aspect of reducing exposure to hazardous workplace noise.

In controlled fit-test studies, users achieved an average measured Personal Attenuation Rating (PAR) of approximately 29 dB when foam earplugs were inserted with the Sert-A-Plug applicator. Individual results vary, and the earplug’s Noise Reduction Rating remains the rating shown on the manufacturer’s EPA-regulated label. Sert-A-Plug is also designated MR Safe under ASTM F2503, making it suitable for use in MRI environments.

The company shares hearing-protection news and research updates, including coverage of its founders and occupational hearing-conservation topics. Sert-A-Plug is based in Lake Oswego, Oregon, and offers its product for purchase through its website.
