3M™ E-A-Rfit™ Dual-Ear Validation System helps determine whether workers are receiving adequate protection from their hearing protector by measuring across 7 standard frequencies in under five seconds, providing a detailed report on the noise attenuation performance of earplugs or earmuffs/headsets and a pass or fail rating for each individual person based on the worker's personal attenuation rating. 

[Features]

• Dual-element, dual-microphone assembly is the key to the system, measuring sound levels inside and outside the hearing protector
• Science-based, quantitative testing gives accurate reports of hearing protection
• Optional Cloud enables stored centralised data, multiple fit testing systems operating simultaneously across sites, and access restricted to authorised users.
• System determines personal attenuation rating (PAR) of individual workers and helps remove measurement, fitting, and spectral uncertainty
• Dual-ear design saves time by measuring both ears simultaneously in under five seconds
• System tests across 7 standard frequencies (125, 250, 500, 1000, 2000, 4000, 8000 Hz)
• Works with a large variety of 3M Hearing Protection Products; earplugs, banded hearing protectors, and earmuffs/headsets
• Simple, easy-to-use intuitive software
• Data can be exported into Excel templates for reports and provide insights to help identify products and techniques that might help improve fit testing efficiency.
• Includes Software, Speaker And Impact Resistant Carrying Case.
• Free online training (with face-to-face options where available) and user support
• Requires probed test plugs, pods, or cushions
• Optional Cloud enables data sync, backup, and recovery
• Customisable menu of hearing protection models available to workers
