听力的比较研究表明，不同种类的哺乳动物听到高频声音的能力与它们的耳朵之间的距离（即功能性耳间距离）成反比。为了确定这种关系是否适用于物种内以及物种间耳间距离的变化，确定了从吉娃娃到圣伯纳德的 4 只狗的听力图。学生们被教导要对音调的存在或不存在做出反应。随后对 15 只狗的耳朵（包括本研究中最大和最小的狗）进行了解剖和测量。结果表明，耳间距离与个体狗的高频听力能力之间没有显着关系。包括鼓膜测量在内的进一步分析表明，耳间距离和鼓膜面积均与狗的高频听力、低频听力或绝对灵敏度的变化无关。（37 参考）（PsycINFO 数据库记录 (c) 2016 APA，保留所有权利）
Comparative studies of hearing have shown that the ability of different species of mammals to hear high-frequency sounds is inversely related to the distance between their ears (ie, functional interaural distance). In order to determine whether this relation applies to within-species as well as to between-species variation in interaural distance, the audiograms of 4 dogs ranking in size from a Chihuahua to a Saint Bernard were determined. Ss were taught to respond to the presence or absence of a tone. The ears of 15 dogs, including the largest and smallest in this study, were then dissected and measured. Results indicate that there is no significant relation between interaural distance and the high-frequency hearing ability of individual dogs. Further analysis, which included measurements of the tympanic membrane, indicated that neither interaural distance nor area of the tympanic membrane is related to variation in high-frequency hearing, low-frequency hearing, or absolute sensitivity among dogs.(37 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
