Reducing Noise Exposure in Powerplants:
Providing engineering solutions to reduce noise to help ensure employee health and safety
"Of our worker's compensation costs, about 20 to 25 percent is due to hearing loss compensation. Dollar-wise, it's the largest single component of claims that we have. This project is an opportunity to protect our employees. Changing the infrastructure protects this and future generations of powerplant employees."

Ultrasound is extremely accurate (greater than 90%) for both maturity status and gender determination, reducing our handling events from four to just two. Ultrasound models are both inexpensive and durable. I would highly recommend investigating this technology for your use."
