Why does wind affect sound so much?
So, sound travels at 700 miles an hour or something through air. Yet it only takes a light gust of wind to noticeably reduce the sound level at a festival. Why should such a slow wind as 30 mph affect the sound so much? Surely it only has to travel a couple of extra metres?
Answers:
It's not just the speed, it's the turbulence reducing the energy in the sound waves. The faster the wind, the more turbulence there is, and this smears out the sound.
Sounds waves are disturbances in air itself. Wind moves air around and takes the waves for a ride.
compression of air particle's
Sound requires a medium to travel through, at a festival this is the immediate air in the vicinity itself. Since this "air" then vibrates to allow the sound waves to travel from the source to the listener, any disturbance of this "air" can affect the sound. Depending on the direction of the wind relative to the outgoing direction of the sound affects how much the sound you hear is affected.
Because sound waves travel by moving air, so a breeze can interupt that wave and cause it to drift up or down in frequency slightly, you notice it more at festivals because theres more air being moved, hence any variation produces a bigger effect.
Drop a stone into a pond this produces a ripple, drop more stones and you get a pattern of waves eminating outwards, sound travels in a similar manner, now drop a stone where you did originally and another immediately a few feet away, the swirling sound at a festival is being produced in a similar way to the way that the second stone interupts the wave of the first.
the sound has to go through a barrier called wind with a partucular density per square inch of pressure as'' varieated'' per wind speed.
EEII how about trying to obstruct sound with light rays or heat and check out the results.... keep me posted -----i will be accepting payments directly in the near future
The movement of air that sound travel on can distort it as well, I am sure you know that moving air also makes a sound and you can hear a mixture of both
You would only really notice that if you were standing outside of the main spectating area. i.e in front of the sound desk and between the two main speaker banks either side of the stage. Its most noticeable when you nowhere near that area like when you go back to your tent for more supplies. The further you are away, the more directional the sound has to be to reach you and therefore more affected by the direction the air is travelling in.
what you must remember is that as sound leaves a speaker it passes through a mesh, this creates areas of maxima and minima. this means that the sound quality can vary depending on where in the field of sound distribution you stand. when such a complex variable as wind is thrown in then even the very medium through which the sound wave is moving is being moved both translationally and vibrationally. this means that interactions between air molecules will be less efficient and the sound will deteriorate more quickly. the more directional the source of the sound the less the wind will have an effect but out of a concert speaker or a persons mouth the sound is spread widely and there is not enough energy to carry the waves as far if there is a wind.
Wind can make sound. I guess it can break it too.
Because wind can be miles deep and miles wide, it has solid matter within in - oxygen, dust particles, salt (chlorine) if you like sciencey words.
Therefore wind has much greater mass than ultra miniscule sound waves enabling it to scatter disperse and absorb sounds energy.
ps. Next time you try to answer one of my questions..read up on the subject. You incorrected stated that no evidence of organisms from anywhere other than Earth have ever been found. I suggest you check with the scientific teams from multiple nations who all examined the Mars meteorite that has a fossil in it. They also all found it to be genuine. When you can explain them they are wrong, then you can come back and have a swing at my question again.
As for telling me to grow up.
Have a nice day !
