Custom made ear plugs will provide the best hearing protection. Many people don’t realize that occasional and intermittent noise in the workplace increases the rate of natural hearing loss. In conditions where noise is persistent or excessive, such as in construction and industrial environments, those who fail to properly protect their ears run a much higher risk of irreversible hearing loss.
Oto’s Ear Defenders provide ultimate protection to those in noise impacted environments.
