Kilobytes Megabytes Gigabytes. The size of information in the computer is measured in kilobytes, megabytes, gigabytes, and terabytes. In this section, we'll look at common sizes you would see in real life, and work some arithmetic. Any thinking person today should have a rough idea of what KB, MB and GB are.
The maximum upper range of human hearing is about 20 kHz for children, declining to 15-17 kHz for middle-age adults. The top end of a dog's hearing range is about 45 kHz, while a cat's is 64 kHz.
As far as making noise voluntarily goes, it is quite common for a turtle to do so during battle, courtship, mating and egg-laying. Most turtle noises are hisses; however turtles have also been known to make noises that include grunting, hooting and clucking. What is even more interesting as far as sound goes is that turtles do not have outer ears. They have inner ear structures but do not necessarily respond to noise.
