Rat’s vocalizations <a href="https://www.metris.nl/media/documents/sonotrack/Rat_mice_USV.pdf">start at around 2 kHz and extend as far up as 100 kHz</a>. For reference, human’s can hear roughly 2-20 kHz, so the vast majority of rat noises made are well into the ultrasonic spectrum. Pet and wild rats alike will seem almost mute, unless put into extreme distress, when they will squeak or shriek audibly.</p> Tue, 30 May 2017 18:16:34 +0000 Ada McVean B.Sc. 2501 at /oss
