“…Some studies focus on the effects of noise in poultry housing caused by ventilation fans and bird vocalizations (Stadelman 1958ab;McFarlane et al 1989a;Campo et al 2005;Miragliotta et al 2006); other studies have monitored the effects of aircraft overflights (Hamm 1967;Book and Bradley 1990). Poultry is often exposed to acute noise levels before slaughter in slaughter houses where noise in the operational plant is caused predominantly by ventilation fans and operational machinery (slaughter line, operating carts, etc.).…”

“…Noise also has an important psychological component, and therefore is a potential source of fear in animals. Campo et al (2005) reported that the tonic immobility duration was significantly longer within a group of hens exposed to noise at a level of 90 dB for 60 min. Authors found this trait consistent with the heterophil to lymphocyte ratio changes.…”

The relationship between noise and indicators of stress in poultry was studied by Borg (1981), McFarlane and Curtis (1989), McFarlane et al (1989b), Gross (1990), Maxwell (1993), Lazarević et al (2000), and Campo et al (2005).

“…Grandin (1996) and Geverink et al (1998) pointed out the instances of poor welfare in slaughterhouses due to excessive noise. Noise as a stress factor in poultry has not been investigated thoroughly, although it seems that it can adversely affect the productive performance and behaviour of the birds (Campo et al 2005). Stadelman (1958a) reported that the sound intensity of 115 dB was effective in interrupting the brooding of hens.…”

Stress effects from acute noise exposure were monitored in a group of ROSS 308 broiler chickens (n = 80), aged 42 days. The experiment simulated slaughterhouse sounds to which the broilers were exposed for 10 min in the test enclosure. Effects of acute noise exposure at two different levels (80 dB and 100 dB) were evaluated on the basis of examinations of selected biochemical plasma indicators and tonic immobility tests. Noise stimuli of both 80 dB and 100 dB intensities for 10 min induced a significant elevation in plasma corticosterone levels. Broilers that were exposed to noise stimuli of 100 dB also exhibited a significant increase in the cholesterol level and total protein level. Exposure to noise stimuli did not influence the glucose level and triglyceride concentrations. The duration of tonic immobility was not affected by noise stimuli in our experiment. However, noise exposure at a 100 dB level decreased the number of attempts to induce tonic immobility in broilers.

Time Course Changes in Selected Biochemical Stress Indices in Broilers Exposed to Short-term Noise

et al. 2010

Time course changes in selected biochemical stress indices (corticosterone, triglycerides, glucose, cholesterol) following short-term noise exposure at 100 dB for 28 min were studied in broilers aged 42 days. Corticosterone concentrations were found to increase during the first 10 min of noise exposure and to differ significantly from the control (background sound -50 dB) at Time 10 min and 14 min, then decreased continually and at 28 min returned to the initial prestress value. Triglyceride concentrations increased in broilers exposed to 100 dB noise during the first 12 min with a significant difference from the control at 12 min and 14 min. Glucose concentrations were higher due to 100 dB noise exposure for almost the entire period monitored, with significant differences between 100 dB and control broilers at 6 min and from 10 min to 14 min. Similarly as for the corticosterone concentration, a drop in triglycerides and glucose concentrations was seen approximately from Time 14 min and a return to the pre-stress value at 28 min. The cholesterol concentrations showed various temporal patterns with no significant difference between 100 dB and control broilers in this experiment. The pattern of response found in the study indicates that 100 dB noise represents a stress factor in broilers, however, there is the ability of broilers to adapt to an increased level of noise at this intensity after the first 14 min of exposure. The findings obtained in the study may contribute to expanding detailed knowledge of physiological stress responses to this specific noise stimulus in poultry, and could thereby be used to improve the welfare of broilers in intensive housing systems.

A comparison of auditory brainstem responses across diving bird species

et al. 2015

There is little biological data available for diving birds because many live in hard-to-study, remote habitats. Only one species of diving bird, the black-footed penguin (Spheniscus demersus), has been studied in respect to auditory capabilities (Wever et al. 1969). We therefore measured in-air auditory threshold in ten species of diving birds, using the auditory brainstem response (ABR). The average audiogram obtained for each species followed the U-shape typical of birds and many other animals. All species tested shared a common region of greatest sensitivity, from 1000 to 3000 Hz, although audiograms differed significantly across species. Thresholds of all duck species tested were more similar to each other than to the two non-duck species tested. The red-throated loon (Gavia stellata) and northern gannet (Morus bassanus) exhibited the highest thresholds while the lowest thresholds belonged to the duck species, specifically the lesser scaup (Aythya affinis) and ruddy duck (Oxyura jamaicensis). Vocalization parameters were also measured for each species, and showed that with the exception of the common eider (Somateria mollisima), the peak frequency, i.e. frequency at the greatest intensity, of all species’ vocalizations measured here fell between 1000 and 3000 Hz, matching the bandwidth of the most sensitive hearing range.
