Soundproofing and Acoustic treatment are two different process. The best way to soundproof is to have a room within a room. The floor should be floating and mounted on rubber stands. The walls should have two frames; the exterior wall (existing building) and the inner wall The studs to join the two frames should be staggered to minimize wave transfer. The ceiling should be ok unless it's a flat roof. All of these things though are structural and it's pretty hard (and expensive) to retrofit a room to be soundproof. Acoustic treatment, such as foams, and insulation don't do anything for sound "proofing" but do control the frequency response of the room. Egg cartons do very little. At most they absorb and diffuse high frequencies. There use as sound proofing is a myth. Things like bradford soundscreen insulation are marketed as sound proofing, but they only absorb certain frequency ranges; such as those the human ear picks up really well. They are good at controlling RT60 and you can make reasonable bass traps with it, but this is all addressing the tonal characteristics of the room rather than sound proofing. This is important because the first thing a lot of people do is mount a whole bunch of insulation panels in order to "soundproof", but then find they suck the life out of the room and it sounds too dark and muddy.

Here's some quick and dirty wave theory for you. Low frequencies behave like liquid. High frequencies behave like light. Low frequencies see a wall and go straight through it and reflect a little. High frequencies will see the wall and bounce back. Sound will propagate at any gap, meaning no matter where the original sound source is, it will appear to be coming from the gap.

Great advice and info!
_________________Spot on advice, a lot of people forget about the floor and that where the bass always goes. Double plastering is a good option but as mentioned all gaps need to be sealed and then you have ventilation issues and would require air con, which would have to be baffled and sealed internally also
