The loudness or intensity of a sound is measured in decibels (dB) with 0 dB being the average intensity of a sound that can just barely be heard by a young human. WebIn his experiments, the subjects were discovered to be able to hear appropriately pulsed microwave radiation, from a distance of a few inches to hundreds of feet from the transmitter.

Sound pressure level normally halves (by six decibels) In this task there are several different options. Sound waves move at different speeds in solids, liquids and gases, and within those states of matter for instance, they travel faster in warmer liquids compared with colder ones.
