生物声学是对动物声音的研究，包括但不限于动物与相关行为的交流，声音产生的解剖学和神经生理学，听觉能力和听觉机制，以及动物福利。本研究调查了马匹在应激状态下的发声情况。压力可以是积极的，也可以是消极的。痛苦是指任何对动物造成负面影响的事情，比如分离母马和小马驹。正应激是任何对动物有积极影响的事情，比如早晨在马棚里喂食的时间。本研究的目的是利用隐马尔可夫模型(HMM)在马匹的发声记录中找出既表示痛苦又表示正应激的频谱差异。Greenwood函数倒谱系数值表明，在痛苦和正常应激状态下的发声之间存在频谱差异。这些一致的结果表明，进一步研究获得和评估马的发声可能会为理解马的福利提供一个富有成效的工具。(C)2010 Elsevier Inc.保留所有权利。
Bioacoustics is the study of sound in animals and includes, but is not limited to, animal communication with associated behavior, sound production anatomy and neurophysiology, auditory capacities and auditory mechanisms, and animal welfare. The present research investigates the vocalizations of horses during stressful situations. Stress can be positive or negative. Distress is anything that affects the animal in a negative way, such as in mare and foal separation. Eustress is anything that affects the animal in a positive way, such as morning feeding time in a horse barn. The purpose of the current research is to find spectral differences in the recorded vocalizations of stalled horses that indicate both distress and eustress using the Hidden Markov Model (HMM). Greenwood Function Cepstral Coefficient values suggest that there are spectral differences between vocalizations in a distress and eustress situation. These consistent results indicate that further research to obtain and evaluate vocalizations of horses may provide a productive tool in understanding equine welfare. (C) 2010 Elsevier Inc.
