Abstract This report summarizes the development and demonstration of retrofit noise control treatments for large track dozers. The noise control treatments were installed on three demonstration dozers (two Caterpillar D9G's and one International TD25D), and field tested for more than 1 year in surface mines. One of the D9G's was equipped with a basic operator cab, while the other two machines had no cab, but were equipped with rollover protective structures. The noise control treatments proved to be both effective and durable. As part of this project, a field manual describing the fabrication and installation of the treatments was also produced. The manual was distributed to mining industry representatives through a series of 1-day workshops that were presented across the United States. A total of 49 workshops was presented to over 800 people. As a result of the favorable reception of the workshops, an audio-visual slide presentation was also developed that summarizes the program.
