Humans can be annoyed or harmed by loud or constant noise, and wildlife can also be affected. Noise can interrupt communication among animals, hunting, foraging, or predatory-evasion abilities. It can cause panic reactions that risk injury to the animal itself or its neighbors. It can cause animals to temporarily or permanently abandon certain areas, in favor of marginal habitats with less noise. On the other hand, some species seem to be able to acclimate to noise after repeated exposure, and not all of the disruptions are permanent. The response of an individual species to certain
types of noise cannot be generalized.29 In a study done in the boreal forest of Alberta that compared bird occurrence and density between well pads, which were considered quiet, and compressor stations, which have a constant noise level of 75-90 dBA, birds were found to occur less often overall the noisier the site was. Some of the individual bird species
were more affected than others by compressor station noise, in fact some species showed no significant difference in abundance among the different site types, but none of them occurred more often at the compressor stations that at the well pads.
