Heavy Industry Hearing Protection

Heavy Industry Hearing Protection: Certified Class-5 Solutions Built for Australia’s Toughest Jobs

In high-noise industrial environments—where machinery roars, metal grinds, and engines thunder—hearing protection isn't optional, it's critical. At Pacific Ears Australia, we specialise in certified Class-5 custom earplugs designed specifically for workers exposed to dangerous sound levels across heavy industry sectors.

From mining and manufacturing to construction, logistics, oil and gas, and beyond, our custom-moulded earplugs are engineered for durability, comfort, and certified protection in the most extreme conditions.

The Urgency of Industrial Hearing Protection

Noise-induced hearing loss (NIHL) is one of the most common and irreversible occupational hazards in heavy industry. Continuous exposure to sounds over 85 dB(A) for an 8-hour period can begin damaging hearing, while exposure to higher noise levels—such as 100 dB—can cause hearing damage in as little as 15 minutes. Without the right protection, long-term noise exposure can result in permanent hearing loss, tinnitus, and a significant decline in workplace safety and communication.

The Heavy Industry Protection range from Pacific Ears is built to reduce these risks—offering certified, high-performance solutions that meet the demands of every shift.

What Class-5 Hearing Protection Really Means

Our products are AS/NZS 1270:2002 certified Class-5, the highest rating available under Australian standards. Class-5 protection means SLC80 ratings of 26 dB or higher, suitable for environments where noise levels exceed 105 dB. These products are ideal for use in sectors where workers face intense daily exposure to machinery, engines, and tools.

Our hearing protection is designed to withstand real-world industrial conditions, including exposure to heat, dust, oil, and vibration. Built with durable, medical-grade silicone and custom-moulded for a secure fit, our products offer long-lasting performance even in demanding environments.

Custom-Fit for Comfort, Safety, and Reliability

Unlike disposable options, our custom-moulded earplugs are made to precisely fit each user’s ears. This ensures a secure, comfortable fit even during long shifts or under safety helmets and PPE.

Key Benefits:

  • ✅ Secure all-day wear—even under helmets or tight headgear

  • ✅ Reusable and washable for hygiene and longevity

  • ✅ Long-term cost savings from reduced replacements

  • ✅ Available with acoustic filters to maintain situational awareness
