What name is given to the sounds which a cat can hear but a human cannot?

Sound with a frequency lower than about 20 cycles per second, called infrasonic sound. Sound with a frequency higher than about 20,000 cycles per second, called ultrasonic sound. Only those with excellent hearing can perceive sound at these extremes. As we age and as our hearing is damaged by exposure to loud sounds, the frequency range of hearing is reduced. Some animals can hear sounds above and below the range of humans.
