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.
The vibrations then enter the internal ears where the vibrations get deciphered and tells the goldfish where that sound is coming form. Even though the ear of a goldfish is more complex they do not have the same hearing range as a human. A goldfish can hear 40 to 3,200 Hz and a healthy human can hear 20 to 20,000 Hz. Many goldfish can pick up on the vibrations or music or even the foot steps of a passerby.
