Because there is nothing to 'absorb' the sound, echo's are basically a sound reflected by it hitting a surface, if you walked into a house with nothing in it, just the walls, floorboards or concrete floor and ceilings then the sound echos because there are no soft things or cushiony things to absorb the sound and stop it reflecting.

Sound in an empty room can be very lod with many echos how can you make it quiet?

To make an empty room quieter, you can add sound-absorbing materials such as curtains, rugs, foam panels, or acoustic tiles to reduce echos. Additionally, adding furniture or bookshelves can help break up sound waves and minimize reverberations.


How are echos related to sonar?

Echos are the reflections of sound waves that bounce off of objects and return to the source. Sonar technology uses these echos to determine the location and characteristics of underwater objects by sending out sound waves and analyzing their reflections. Therefore, echos are essential for sonar systems to function effectively in detecting underwater targets.


What are the empty areas around other objects in an artwork?

The empty areas around objects in an artwork are called negative space. It helps to define the boundaries and shapes of the objects and plays a crucial role in the overall composition and balance of the artwork.


Echos occur when a sound wave from an obstacle.?

reflects off an object and returns to the listener's ear, creating a delayed repetition of the original sound. Echos are heard when the distance between the listener and the reflecting surface is great enough for the sound to travel and return in noticeable time.


Why does an empty vessel produce more sound than a filled one?

An empty vessel produces more sound than a filled one because the empty space inside allows sound waves to bounce around and amplify, creating a resonating chamber. In contrast, a filled vessel dampens sound waves as they are absorbed by the material inside, significantly reducing the volume of sound produced.
