- 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
- 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
- Simple, easy-to-use intuitive software
