Abstract This report presents a comprehensive overview of an EPA-sponsored program to demonstrate the technology and costs of reducing the noise of four heavy-duty diesel trucks to 72 dBA. The program comprised engineering development and service evaluation phases. Noise control treatments were developed and installed on each truck to reduce its noise to the target level. The treatments included partial engine and transmission enclosures, exhaust silencing systems, and two-stage engine mounts for 2 of the 4 trucks. Three trucks entered fleet service where they accumulated 230,000 miles. The treatments proved to be durable and effective and did not have an adverse impact on the operation of any vehicle. Maintenance labor time increased by 1.4% because of the need to remove enclosure panels while performing some maintenance procedures.
