auditory range

“There are significant pressure changes, frantic winds, massive electrical discharges, concussive sounds: Dogs can hear above and below our auditory range,” said Dr. Peter H. Eeg, a veterinarian in Poolesville, Md., who has been reporting Sileo results in patients to Zoetis, the company that distributes the drug.

Humans are known to have a distinct auditory range among primates, with particular sensitivity between 2 and 4 kilohertz.

The scientists then used a computer algorithm that converted the visual data to acoustical information and sped up the frequency of the sound so that it would fall within the human auditory range.

Some have an extended upper auditory range and can hear dog whistles or the shrill hiss of a department-store electronic security system.
