• acoustic
  • A unidirectional microphone positioned about 15 cm from the animals' mouth was used for recording the acoustic signals. (mdpi.com)
  • Among the numerous advantages of acoustic signalling, like independence from daylight, the minor influence of obstacles on sound propagation, and the large distances which can be covered, the independence of vocalizations from any ongoing motor activity - in the human the independence from the hand-eye interaction during tool making and using - may be the reason for this success. (springer.com)
  • Knowledge of species-specific vocalization characteristics and their associated active communication space, the effective range over which a communication signal can be detected by a conspecific, is critical for understanding the impacts of underwater acoustic pollution, as well as other threats. (peerj.com)
  • There is a development shift however from the Lombard effect being linked to acoustic self-monitoring in young children to the adjustment of vocalizations to aid its intelligibility for others in adults. (wikipedia.org)
  • Vocalizations in adult penguins can be classified into 4 distinct categories based on its acoustic properties and the behavioural context in which a vocalization is produced. (wikipedia.org)
  • Distress
  • Results indicated that vocalization might be an effective welfare indicator, and it could be applied for assessing distress from pain, cold and hunger in farrowing piglets. (mdpi.com)
  • Distress related vocalization is of particular interest as an indicator of impaired welfare [ 1 , 2 ], and it is an objective and noninvasive procedure that has been studied to estimate pigs' welfare [ 3 , 4 , 5 , 6 ]. (mdpi.com)
  • The most common tactic for hunting coyotes and bobcats is attempting to lure them into range with a call designed to mimic an animal in distress. (eveningtribune.com)
  • Vocal
  • Vocal signals were collected from 40 animals under the following situations: normal (baseline), feeling cold, in pain, and feeling hunger. (mdpi.com)
  • The intelligibility of an individual's own vocalization can be adjusted with audio-vocal reflexes using their own hearing (private loop), or it can be adjusted indirectly in terms of how well listeners can hear the vocalization (public loop). (wikipedia.org)
  • Devocalization (also known as ventriculocordectomy or vocal cordectomy and when performed on dogs is commonly known as debarking or bark softening) is a surgical procedure performed on dogs and cats, where tissue is removed from the animal's vocal cords to permanently reduce the volume of its vocalizations. (wikipedia.org)
  • This vocal individuality can convey information such as body size and weight, since heavier penguins typically emit longer and lower-pitched vocalizations. (wikipedia.org)
  • studies
  • There are other techniques to recognize stress in animals, e.g., a stress response as an adrenaline release can be accompanied by changes in the rates of specific types of vocalization [ 7 ] while other studies suggested an increased rate of vocalization in pigs after receiving corticotrophin injections [ 8 ]. (mdpi.com)
  • behaviors
  • In playback experiments, certain behaviors that occur commonly after vocalizations are scored before and after a call is played. (wikipedia.org)
  • These behaviors include lifting and stiffening of ears, vocalization, walking or running towards the concealed speaker, clustering in a tight group, and remaining motionless ("freezing"), with occasional scanning movements of the head. (wikipedia.org)
  • temporal
  • Although spectral representation was not changed for animals reared in the faster or slower rate, temporal rate representation was improved. (jneurosci.org)
  • The term is not clearly defined in the scientific literature, though most investigators agree that an animal song must have syllabic diversity and temporal regularity akin to the repetitive and transformative patterns which define human music. (wikipedia.org)
  • elephant
  • One of the biggest threats to elephant populations is the ivory trade, as the animals are poached for their ivory tusks. (wikipedia.org)
  • found
  • We found that, using the piglets' vocalization, it was possible to identify the most frequent stressful conditions at the farrowing phase, namely: pain, cold and hunger. (mdpi.com)
  • Noise has been found to affect the vocalizations of animals that vocalize against a background of human noise pollution. (wikipedia.org)
  • Experimentally, the Lombard effect has also been found in the vocalization of: Budgerigars Canaries Cats Chickens Common marmosets Cottontop tamarins Japanese quail Nightingales Rhesus macaques Squirrel monkey. (wikipedia.org)
  • 2002) found that playback of calf vocalizations caused a statistically significant increase (1-2%) in milk production in dairy cows. (wikipedia.org)
  • occurs
  • Most owner complaints about feline vocalization are either to do with the intensity and persistence of the vocalization, or the fact that it occurs at night or at other times when family members or neighbors are trying to sleep. (vcahospitals.com)
  • Although
  • Although it is of great relevance, the assessment of animal welfare status in commercial farming is still a difficult task. (mdpi.com)
  • indicator
  • The data also support gakel vocalization as an indicator of stress/discomfort in chickens, which are notoriously stoic and therefore have been hard to assess for well-being, historically. (wikipedia.org)
  • further
  • therefore, it is possible that milk production within a dairy herd could be increased further if multiple playbacks of calf vocalizations were used, varying by age as appropriate for the cows (McCowan 2002). (wikipedia.org)
  • active
  • Of course, since some cats are quite active at night, it is not surprising that many owners are concerned about their cat's nighttime vocalization and activity. (vcahospitals.com)
  • time
  • As in Mycenaean Greek, Homer used the Greek word to mean ivory, but after the time of Herodotus, it also referred to the animal. (wikipedia.org)
  • Spending more time with an animal, such as playing, walking, and other bonding activities, will keep them occupied and make them feel more at ease. (wikipedia.org)
