Why are echos produced in empty areas?
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.
What are objects that absorb sound?
Usually, stuff that is soft will absorb sound.answ2. Sound is a vibration of air molecules, and anything that may be made to absorb energy from the molecules will absorb sound. If the material has soft fibres, and can allow the sound to penetrate easily, (is porous) then the collision of sound molecules with the fibres, will transfer the energy from the molecules to the inelastic fibres, where it will be dissipated as heat.
Can soft and rough surfaces absorb sound?
The natural property of the material has that ability. Alot of objects absorb wound, for example the sides of your stereo are sound insulators. However, not all have the same or even this ability at all. As for soft and rough, they most likely won't play a factor, therefore you should look into the material of objects to possibly determine the insulation of sound.
Do clocks absorb sound?
No they most definitely do not absorb sound
Why sound is heard louder but unclear in empty room?
In an empty room, the sound is mostly just bounced around. When more things are placed in the room, they provide more ability to absorb sound and reflect in different directions such that it actually has to take a longer path to get from one place to another (zig zag instead of straight path) with the consequent attenuation of the intensity of the sound. Mostly though it's the absorption of the sound by the stuff you fill the room with.If a room has things like soft chairs, sofas, beds, etc, they serve to absorb some of the sound waves.

What are the things that produces soft sound?
bibs
Does aluminium absorbe sound?
This much depends on the properties of the plastic. Foam will reflect little and absorb much. Hard plastic will reflect much and absorb little. Soft plastic will absorb more than hard plastic and reflect more than foam. Regards.

What things absorb sound?
well sound is adsorbed by dence fabrics like carpet, yet wood amplifies sound (by a small margin). rugs, bed linin, blankets..... things like that.
Does concrete absorb sound?
No, concrete does not absorb sound as it very dense.
State five things that you know about sound?
1 sound can be loud 2 sound can be soft 3 there are many different types of sound 4 many things make sound 5 sound is made in different ways
Is maracas a loud sound or soft sound instrument?
SOFT

How echo is formed?
An echo is formed by sound waves bouncing back off of solid surfaces. The greatest effect happens in small empty rooms with few or no soft furnishings. Soft furnishings absorb sound waves and so would counteract the effect.
