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.
It is common for people to experience slight hearing loss as the age. This is caused by changes in the inner ear. An average middle-aged person can detect a maximum frequency of 12,000 Hz to 15,000Hz. Some animals have wider frequency ranges. For instance, dogs have an average frequency range of 67 to 45,000 Hz, and dolphins have a maximum frequency range of up to 100,000 Hz. Learn more about Human Anatomy
