Custom Moulded Ear Plugs

A custom-moulded earplug is a laboratory-made earplug made from moulds taken by trained, experienced professionals. Most often, ear impressions are made of acrylic or soft silicone that can fit the ear and ear canal tightly. Softer earplugs change shape slightly as the wearer’s ear canal changes shape when talking or chewing, thereby continuing to seal during those activities While disposable earplugs may seem like a quick fix, it is important to consider the costs associated with ongoing replacement, infection due to overuse, damage resulting from improper use, and your employees’ overall comfort level, which will ultimately affect their productivity.

Our custom plugs are made of medical-grade silicone that is soft, yet durable enough to last 5 years or more with proper care. They also come with a protective case to prevent accidental loss. With a variety of styles to choose from, that can all be customized to ensure the appropriate attenuation, you can feel confident knowing your employees will be safe, healthy, and productive on the job.

            Your ears need to be properly cared for on a regular basis. Custom earplugs help protect your employees, but to truly understand whether a worker’s hearing is being impaired as a result of job-related activities, SureHire recommends performing baseline testing prior to employment followed by periodic testing to measure changes in hearing acuity. Learn more about our audiometric testing services.
