Advancing the Science of Hearing Protection with dB Blockers®
At Custom Protect Ear, we are committed to advancing the research and development behind hearing protection. Our innovative dB Blockers® are designed to safeguard workers from noise-induced hearing loss (NIHL) in various industrial environments. With custom-fitted hearing protection solutions, we address the unique challenges posed by occupational noise, ensuring your workforce is protected.
High Noise Environments
In high-noise environments, hearing protection is essential to prevent noise-induced hearing loss. OSHA sets an action level for hearing conservation at 85 dBA, with mandatory hearing protection required at 90 dBA. NIOSH recommends an action level of 85 dBA across all hearing conservation programs. However, noise levels in heavy industry can reach up to 120 dB, posing a significant risk for long-term hearing damage from prolonged exposure. Custom Protect Ear's dB Blockers provide specialized hearing protectors designed to safeguard your hearing in extreme noise, ranging from 105 dB to 110 dB. In Canada, mandatory hearing protection is 85 dB, and dual protection is 105 dB.
