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...
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...
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),...

Multifactorial testing of enrichment criteria: pigs 'demand' hygiene and destructibility more than sound
Contributor(s):: Bracke, M. B. M.
To validate (further) a semantic model called RICHPIG, which was designed to assess enrichment materials for pigs, a study was conducted to examine the importance of three assessment criteria, namely destructibility, hygiene and sound. These material properties were studied using a specially...

The influence of auditory stimulation on the behaviour of dogs housed in a rescue shelter
Contributor(s):: Wells, D. L., Graham, L., Hepper, P. G.
This study explored the influence of five types of auditory stimulation (human conversation, classical music, heavy metal music, pop music and a control) on the behaviour of 50 dogs housed in a rescue shelter in the UK [date not given]. The dogs were exposed to each type of auditory stimulation...
