"Minetek site specific engineering provided the sound attenuation solution that has solved our client’s noise challenge."
Jim Sealey – Divisional Manager – Sound
A leading Chilean copper mine required a sound attenuation solution to meet strict noise compliance targets across its fleet of Caterpillar 789C and 789D haul trucks and 994K loader.
Using our M‑STEALTH™ Sound Package, we reduced noise by up to 8 dB(A) on the haul trucks and 4 dB(A) on the loader, enabling compliant operation hundreds of metres closer to site boundaries.
The solution was delivered without breaching environmental noise limits or compromising equipment performance, airflow, or thermal integrity.
