Highlights
  • 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
  • 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

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.
