Answer 1

Answer:

1. An ultrasound is a type of oscillating sound pressure wave that has a higher frequency than human hearing is able to detect. An ultrasound is not a unique type of sound, therefore, but is classified differently due to the fact that humans cannot hear it.
2. Our ears can detect only a relatively small range of frequencies of vibration. Beyond what we can hear there is: Infrasound, where the rate of vibration is too low for us to hear. Ultrasound, where the rate of vibration is too high for us to hear.
