If you had 1 speaker (for e.g.) playing music at a certain volume level, what would happen of you had a 1000 speakers all playing at the same volume level...would the volume level stay the same or be increased? Does it depend on the size of the room that the speakers are in...if this is confusing...then compare to 1 person talking to 1000 talking...the sound is louder but is that because everyone is speaking louder to be heard? Would the volume level increse by the amount of speakers (e.g. x1000 if there are a 1000 more speakers) OR is there a mathematical equation to work it out?

The answer is yes, but I speculate sometimes that more than one source of the same frequency at different locations could be in anti-phase and add up to zero sound!
e.g. Place your two stereo speakers facing each other a short distance apart and compare the sound levels (particularly the bass) when you reverse the cables on one speaker.

I don't know this for fact but I'll have a go and no doubt someone who is cleverer than me will give you a cleverer answer.
It will depend on the size of the room but in any case adding speakers would only increase the perceived volume up to a point. And in any case the volume would not initially increase 100% simply by doubling the number of speakers.
Given that all the speakers had the same power output and were all set at the same volume, then it would appear louder for each added speaker but only until at every point in the room the maximum volume/power out put could be heard. At that stage it would not matter how many more speakers you added, to make it any louder you would have to turn the volume up.
I do believe that adding additional speakers will make the sound richer and accousticly superior as the sound would be all around you, but it would actually not be any louder.

If you had 1000 speakers playing at the same volume level, the volume level is increased because you receive more power.
Volume depends of geometry of the room and positions of speakers.
You can not say that volume will be 1000 times bigger.

if u put a speaker into a big room it will have a sound if u add another speaker the sound will increase ... its like increasing the sound at a speaker only..
and the 1000 person make more sound that 1 person not because they are tring to be heard but just ....1 person make for example 4 waves of sound but 5 person make 4* 5= 20 ...
got me ????

Sound is based on sound level energy (measured in Watts or bels). If you increase the number of sources, each putting out the same sound level energy, the total energy increases relative to the increase in sources. The size of the room doesn't change the sound level output, but there is a decrease in how the human ear perceives the sound level, and there is also attenuation of sound by distance (sound decreases by an inverse squared value as you move further from the source).
There are several mathematical models to deal with sound, not enough room, time, or willingness on my part to list them here.

basically when there are many speakers playing at the same time, lots of sound waves are transferred by the speakers which then interferes with each other hitting themselves and distorting the shape of the waves. The distorting effect makes the sound seem scratchy. But when all speakers are playin the same sound, the waves are all the same so no distortion occurs.

Multiply the number of speakers playing and you increase the noise level linearly....double the # of speakers and you double the noise level.
That assumes each is on its own source (amplifier) and adding speakers does not reduce the amp's output.
Same as one person cheering in a stadium vs 50,000 cheering.

Your brain makes sense of noise because the thin layer of skin in your ear called your eardrum vibrates if two people talk at the same level then your eardrum will vibrate twice as much. Your on your own from there lol Noise needs something to bounce off and it needs a brain to interpret the noise.

when the surface is parallel, the sound is not refracted by the surface. for eg; when a light ray is focussed on a parallel plate they reflect and not refract. more over the surface is parallel there may not be any diffusion. as per acoustics only cardboards and some other materials absord sound and since it is parallel i think it does not absorb the sound. then it is ounly by focussing

sound is a wave and if waves are of the same wave length or frequency they add up hence the volume is increased.
