Low welfare impact of noise : assessment in an experimental model of mice infected by Herpes simplex-1 (2018)
Journal Article

The breeding practices adopted and the equipment typically found in animal facilities produce sounds at frequencies within the auditory range of the mice (1 to 100 kHz), which can cause hearing and other non-hearing effects. Another aspect that could... Read More about Low welfare impact of noise : assessment in an experimental model of mice infected by Herpes simplex-1.

Comparing contact calling between black tufted-ear marmosets (Callithrix penicillata) in a noisy urban environment and in a quiet forest (2017)
Journal Article

All habitats have some level of noise but anthropogenic sounds such as those produced by traffic are structurally different from natural sounds, and could cause organisms living in noisy urban areas to modify their vocal communication. We compared te... Read More about Comparing contact calling between black tufted-ear marmosets (Callithrix penicillata) in a noisy urban environment and in a quiet forest.
