I have a problem with sound travelling between walls - is there any way to insulate a wall that is existing without taking down drywall and creating big mess with big price tag? Can you make a hole in the 2x4 and spray insulate?

It is usually a lot easier to take one side of the drywall down, insulate the wall and repair, than it is to try and squirt something down the cavity and hope that it is going where it is needed.
There are different means of sound insulation depending on the circumstances... Acoustic engineers take into consideration the background noise (does a train go past every 30 seconds) etc and actually calculate the resistance needed to achieve the required outcome. Even if you are doing it yourself, you also need to investigate the level of sound attenuation that you need... for example, if the people in the adjoining room are screaming all night you need better isolation of the structure than if they are simply watching TV on an average volume. Your best solution might be to add a layer of foam and impregnated vinyl, then build a separate wall in front of the existing one... obviously you need an expert to get it right.
Just locating insulation in the wall is going to help but it may not be an adequate solution and your effort will be for next to nothing. And beware... often the sound seems to be coming through the walls but it is actually coming through the ceiling (where the wall abuts the ceiling).
Sorry to be the bearer of bad news.. but you need to investigate the matter properly before you commit money and effort to it.

Making a hole and spraying insulation will not solve your problem due to the way walls are framed. If it is an exterior wall, you should consider changing the siding or the windows and doors.
Building a new wall on top of the problem wall with up to date insulation is the best and cheapest way to keep out the sound.

i would suggest cutting at the top of wall and shooting insullation into wall and then adding another 4x 8 sheet ontop of existing wall

just some used paper egg trays will do the trick. sounds can be absorbed by soft or very hard surface or materials
