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 and a pass or fail rating for each individual person based on the employee’s personal attenuation rating. Objective, dual ear test, takes only seconds to administer for 7 standard frequencies Dual-ear design saves time by measuring both ears simultaneously in under five seconds Dual-element, dual-microphone assembly is the key to the system, measuring sound levels inside and outside the hearing protector Fast, clear, accurate results are obtained in just seconds and can be printed or saved electronically for future reference System determines personal attenuation rating (PAR) of individual workers and helps remove measurement, fitting, and spectral uncertainty Requires probed test plugs Includes Software, Speaker and impact resistant Carrying Case Includes Software, Speaker And Impact Resistant Carrying Case. Free online training and user support Requires probed test plugs, pods, or cushions
