The most important thing to remember about Plugfones is that they're earplugs first and earbuds second. As such, the entire Plugfones line is tested and compliant with ANSI S3.19-1974 noise reduction standards and meets NIOSH criteria. When used as directed, our products are certified for Noise Reduction Ratings (NRR) of 23 or 26 dB, depending on the plugs used. For environments with high levels of noise, it may be necessary to use over ear protection such as earmuffs in conjunction with Plugfones products.
Safety is key to the success of any workplace project. That's why we've worked closely with OSHA's max volume guidelines to create our VL Plugfones. VL models feature volume limiting technology that keeps speaker volume below 82 dB, which is compliant with OSHA's standards. On these VL marked products, specially tuned drivers restrict volume levels from reaching the full capabilities of the attached device.
