Number of nearby visitors and noise level affect vigilance in captive koalas
Contributor(s):: Larsen, Megan J., Sherwen, Sally L., Rault, Jean-Loup
Understanding human-animal interactions is particularly important for institutions that display animals to the public due to the frequent, and sometimes intense, interactions with unfamiliar humans. Past research has shown that visitors can have a negative impact on the welfare of a wide range of...
Can the location of cattle be managed using broadcast audio cues?
Contributor(s):: Umstatter, Christina, Brocklehurst, Sarah, Ross, David W., Haskell, Marie J.
Fences are crucial for successful grazing management of livestock. However, conventional fencing is expensive and lacks spatial flexibility. To date, this flexibility has been provided by electric fences, but these are not always efficient to erect and move and are not suitable for all locations....
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...
Understanding Animal Detection of Precursor Earthquake Sounds
Contributor(s):: Michael Garstang, Michael C. Kelley
We use recent research to provide an explanation of how animals might detect earthquakes before they occur. While the intrinsic value of such warnings is immense, we show that the complexity of the process may result in inconsistent responses of animals to the possible precursor signal. Using the...

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...

Why do large dogs sound more aggressive to human listeners: acoustic bases of motivational misattributions
Contributor(s):: Taylor, A. M., Reby, D., McComb, K.
Previous research has highlighted that while human listeners are capable of estimating the body size of dogs using the acoustic components of their growls, they also rate growls from larger dogs as more being aggressive than growls from smaller dogs. The aim of this study was to investigate the...
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...
Development of a behavioural test of sensory responsiveness in the growing pig
Contributor(s):: Hutson, G. D., Ambrose, T. J., Barnett, J. L., Tilbrook, A. J.
The responses of individual growing pigs to 60 stimuli from 5 sensory categories were evaluated as an initial step in developing a behavioural measure of welfare. Pigs were exposed to the stimuli in a test pen after being trained to eat from a food box adjacent to a stimulus presentation box. The...
Social eavesdropping in the domestic dog
Contributor(s):: Marshall-Pescini, S., Passalacqua, C., Ferrario, A., Valsecchi, P., Prato-Previde, E.
Eavesdropping on third-party interactions has been observed in a number of species and is considered an important source of information in decision-making processes relating to fighting and mate choice. Human beings, however, use publicly available information flexibly in many different contexts...

Behavioural and physiological responses of pigs to sound
Contributor(s):: Talling, J. C., Waran, N. K., Wathes, C. M., Lines, J. A.
Eight piglets were exposed to artificially generated sounds, nominal intensities of 85 or 97 dB(Lin), and frequencies of 500 or 8000 Hz for 15 min during a 1-h experimental period. In a 2nd experiment, 8 piglets were exposed to 20 min of farm sounds (Leq 80 dB), transport sounds (Leq 83 dB),...
