Why does sound differ if heard from a distance and near?
As distance from the sound source increases, the area covered by the sound waves increases.
The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less.
This explains why even loud sounds fade away as you move farther from the source..
How do you hear sound from far away?
Shaped like satellite dish antennas, these special microphones amplify sound coming from an area that’s too far away to hear clearly without the aid of a listening device. By pointing the device at a desired location, sounds from as far as 300 yards (274.3 meters) away can seem like they’re right next to the listener.
How do you know if your hearing is damaged?
