Why do Animals make Noise?
In most cases it is very good for animals to lie low in order not to be discovered by animals of prey. But sometimes it is also incredibly helpful to be loud. For instance, wolves are howling to defend their territory, and whales try to find each other at distances of several 100 kilometers. The chirping of cicadas however is a mating call.
What are Decibels?
Decibel is a measuring unit for sound volume. The unit is actually called Bel and was named after the inventor Alexander Graham Bell (who is also regarded as the inventor of the telephone). Yet, most of the time we use the term decibel (deci = a tenth).
What Humans Can Hear ...
A normal conversation between two people takes place at about 60 dB. Our ears begin to ache at a noise level of 120 dB. At 160 dB, the ear drum might even get damaged.
... and What They Don’t Hear
Humans can only perceive sounds within the range of 20 Hz and 20 kHz (= Kilohertz = 20,000 Hz). Hertz is the unit indicating the sound frequency. Giraffes use sounds below the level of 20 Hz when they “talk”. The call of a bat has a sound frequency of 14 - 100 kHz! By the way: It also works the other way round: Some animals cannot hear sounds that we can clearly perceive.
