Why Doesn’t the Sound Resonating in the Mountains Resonate in a Furnished House?

Especially at young ages, shouting towards the view when you go to an open and high area It has undoubtedly been one of your biggest hobbies. However, you cannot experience the same excitement when you come home.

Alright What is the logic behind this?

An echo is a sound that returns to its source, like a boomerang.

In order for the reflected sound to be perceived clearly, be of sufficient size and return with a certain delay must. Delay is directly proportional to the distance of the reflective surface from the source of the sound and the listener.

Our ears are actually kind of, These are hearing aids that are worn on both sides of our heads. After a sound is emitted, if the delay is less than a tenth of a second, the human ear cannot distinguish the perceived sound from the original.

Let’s assume that the speed of sound in air is approximately 340 m/s.

The total distance traveled by the sound in this narrow interval of 0.1 seconds is 34 meters. This, the reflected sound can be distinguished from the incoming sound and therefore perceived as an echo means the obstacle must be at least 17 meters away.

When the echo returns within 1 second, the obstacle is 170 meters away. Similarly, echo When he returns 2 seconds later he is 340 meters away.

Also echo, reverberation should not be confused with . The major difference between echo and reverberation is that an echo is a wave that is received and reflected in a tenth of a second.

This means that the obstacles are placed at very short distances, especially less than 17 metres.

In other words, the reason why echoes can be heard in the mountains but not in the rooms is, Receiving reflected sounds in less than 0.1 seconds or the reflecting surfaces are at distances of less than 17 metres.

On the other hand, while you can hear echoes in an empty apartment, it is not possible to hear them in a house full of furniture. The reason you can’t hear echoes in a furnished house is because furniture absorbs sound to reflect it.
