Research to determine noise impacts on animals benefits from methodology that adequately describes the acoustical stimulus as well as the resulting biological responses. We present acoustical considerations and research techniques that we have found to be useful.

Resolution Copper will use these techniques to ensure that the subsidence associated with its underground operations is predicted with a high degree of confidence, is monitored, is controlled, and that a process of continuous improvement is implemented as mining expands and further knowledge is gained.

Mineral Creek is a tributary to the Gila River in Pinal County Arizona. Mineral Creek is impounded by Big Box Dam just upstream of ASARCO Ray Mine.
