Answer 1

THe range of human hearing is between 20 and 20,000 Hz. So the only number that falls outside that range is A

Answer 2

The correct option is A.
Humans use the two ears to pick up sound waves and vibrations. The ears can not perceive sounds whose frequency is too low or too high. The sound frequency, which human beings are able to hear ranges from 20 to 20,000 HZ. As an individual gets older, the hearing range for the person become reduced. Studies have shown that, older men experience loss in hearing range more than older women.
