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.
At peak functioning, human ears can hear sounds at frequencies up to 20 kilohertz. Depending on size, breed, and age, the high end of a dogâs hearing ranges from 40 up to 60 kilohertz. The sound of the typical ultrasonic dog whistle varies between 23 and 54 kilohertz. Dog whistles work in the same ways that any other modes of training do, and for the same reasons; to wit, dogs are consistently trained to respond in a certain fashion to their use.
