Stereo-sound amplification allows the user to identify warning signals while maintaining effective communication without removing the earmuff. Obviously, the stereo sound quality and ease of use make electronic or communication muffs an important option in hearing protection. Increased productivity, worker acceptance and improved safety balance the additional cost of electronic muffs. As with other personal protective equipment, OSHA requires proper care for electronic muffs. Electronic muffs have removable cushions for ease of cleaning and replacement.
Most manufacturers offer hygiene kits that include replacement cushions and foam inserts.
Use only a mild soap or detergent to clean cushions and earmuff exteriors. Do not use alcohol or solvents. You may use a disinfectant such as benzalkonium chloride. Do not allow cleaners to contact the electronic circuitry or components. Typically in this type of operation, there is a wet and dry end to the line.
