The HEARPLUGZ Attenuation Study was conducted from 50dBa to 110dBa verifying how NRR values increase as noise levels increase. When compared to average performances from solid ear protection, HEARPLUGZ clearly demonstrate the ability to hear critical sounds better while suppressing unwanted noise.
Supply in three different sizes:
