Sound is a wave and by wave i mean sound wave.a wave is a disturbance caused by a vibrating medium e.g air,water e.t.c. Waves occupies space which means they have mass(matter).soundwaves travells through the air when anything is pluncked or made to vibrate.if sound have mass dat means it is a three dimensional quantity(lenght,breath and volume) and from einstein relativity formula anything that have mass also have a certain amount of energy E=mc^2 (E=energy,m=mass and c=speed of light).so therefore soundwaves carries energy and if sound is a wave it must exibit some features of wave e.g reflection,refraction and diffraction.when soundwaves hits a hard surface it is reflected but when it hits a soft surface part of itz energy is being absorbed by the soft surface which wil reduce the strength of sound bein reflected....
by sound waves they send out
the interaction between sound waves is called interference.
The three ways that sound waves interact are: reflection, diffraction, refraction.
Particles in gases are very far apart and there is a negligible amount of attraction force between these particles. Gas molecules have to move a long way before they interact and collide with other molecules. Sound energy slows down and does not move face when the molecules are not in contact with each other.
Sound certainly can travel around corners. Sound can also travel through hard surfaces like walls and bathroom surfaces as well.
Since sound reflects off of soft surfaces better, it can reflect off of metal, walls, wood, paper, and a bunch of more soft surfaces.
Reflection is the return of sound waves from surfaces on which they are incident.
Some surfaces reflect sound well, others don't.
a solid surface
By lining the walls and other hard surfaces with curtains, drapes, foam panels, or other sound absorbing materials.
the more smooth the surface is the better the sound is
Sounds seems to echo in an empty room because the sound has only six surfaces to bounce off of. When the sound waves bounce, they bounce right back to the source. However, when there is furniture, pictures, and other objects placed in a room, those surfaces contain just about every different angle, and when sound hits them, they bounce every but back to the source, hence, little to no echo.
