Altered acoustic environments influence boldness in minnows
Contributor(s):: Hasan, Md Robiul, Crane, Adam L., Poulin, Nicolas P., Ferrari, Maud C. O., Chivers, Douglas P.
Human-induced noise has a pervasive influence on the behaviour of animals in their natural environment, but little scientific attention has gone toward noises that regularly affect animals being maintained in captivity for research purposes. Here, we assessed underwater aquarium noise produced...
Do audible and ultrasonic sounds of intensities common in animal facilities affect the autonomic nervous system of rodents?
Contributor(s):: Burwell, A. K., Baldwin, A. L.
In animal facilities, noises, often poorly controlled, occur over a wide range of frequencies and intensities. Evidence demonstrates that audible noise and ultrasound have deleterious effects on rodent physiology, but it is not known how they affect the autonomic nervous system (ANS). This study...
Noise exposure, music, and animals in the laboratory: a commentary based on Laboratory Animal Refinement and Enrichment Forum (LAREF) discussions
Contributor(s):: Patterson-Kane, E. G., Farnworth, M. J.
The effects of noise, in general, and music, in particular, on the behavior and welfare of animals in the laboratory deserve a great deal of empirical study. However, many laboratories must develop their current practices on the basis of sparse and conflicting data. With this commentary we seek...
Noise in the animal shelter environment: building design and the effects of daily noise exposure
Contributor(s):: Coppola, C. L., Enns, R. M., Grandin, T.
Sound levels in animal shelters regularly exceed 100 dB. Noise is a physical stressor on animals that can lead to behavioral, physiological, and anatomical responses. There are currently no policies regulating noise levels in dog kennels. The objective of this study was to evaluate the noise...
The response of beef cattle to noise during handling
Contributor(s):: Waynert, D. F., Stookey, J. M., Schwartzkopf-Genswein, K. S., Watts, J. M., Waltz, C. S.
59 yearling beef heifers (362+or-26 kg) were used in a study to evaluate their behavioural and physiological response to noises during a 1 min exposure. In Trial 1, 29 heifers that were naive to the treatments were assigned to either prerecorded handling noise (Noise, n=14) composed of humans...
Recorded sounds associated with feeding did not affect feeding behavior of lambs

Sound avoidance by domestic pigs depends upon characteristics of the signal
Contributor(s):: Talling, J. C., Waran, N. K., Wathes, C. M., Lines, J. A.
Two groups of 12 pigs, weighing 25 kg, were individually exposed to a test sound in a modified unsignalled one-way avoidance procedure. The test sound for the first group was a recording from an animal transporter played at 84 dB(Lin), with a rise time of 2 s (uniform). For the second group,...
