What term describes high-frequency sounds that impact animal behavior?

Ultrasonic sounds are defined as high-frequency sounds that are above the range of human hearing, typically greater than 20 kHz. Many animals, including dogs and cats, can hear these sounds and often respond to them in unique ways. For example, ultrasonic sounds are used in various training tools, such as dog whistles, which emit sounds that are inaudible to humans but can capture an animal's attention. This sensitivity to high-frequency sounds can significantly influence animal behavior, as some species utilize these frequencies for communication or to detect prey.

In contrast, infrasonic sounds are low-frequency sounds below the threshold of human hearing and are less relevant to the question of high-frequency impacts on behavior. Audible sounds fall within the range of human perception and do not encompass the specific effects of high-frequency sounds experienced by animals. Subsonic sounds also refer to very low frequencies and do not pertain to the context of high-frequency auditory stimuli impacting animal behavior. Thus, ultrasonic sounds are the term that accurately describes the influence of high-frequency sounds on animal behavior.
