The new VeriPRO test package provides safety managers and employees a way to ensure the effectiveness of hearing protection devices, according to VeriPRO maker Howard Leight by Sperian. Developed in collaboration with the House Ear Institute, the VeriPRO package includes software and an optimized headset used to measure real-world attenuation of unmodified earplugs. Through a three-part process, VeriPRO measures the effectiveness of an employee’s earplug fit over a range of frequencies. The resulting Personal Attenuation Rating (PAR) indicates the actual protection an employee gets from his or her earplug, Sperian says. It says VeriPRO is compatible with any earplug and offers two test protocols: the Complete Check, which runs through five frequencies for PAR determination, and Quick Check, a one-frequency test of earplug fit.
