Sound vibrates the molecules in the wall the same as it des the molecules in the air - is my understanding anyway. So airborne and structure borne transmission are essentially the same thing.

This is why we continue to dither about 'downsizing' from a house to a flat. We have good thick walls, and relatively quiet neighbours, and remember back when we lived in a flat. The woman above us seemed to be permanently hoovering, whilst the woman in the flat next to us played opera very loudly all day and well into the night. She was a bit crazy, and had barricaded the way to her door with bins and cardboard boxes to hinder people from complaining to her about the noise. And we lived on the ground floor. Imagine having noisy neighbours above and below you!
i got offered a modern flat down rd from me by the housing association as i am disabled.. I said over my cold, dead body ;) couldnt stand having so many folk around me. Ive only one neighbour with a connection to house. am an end terrace with driveway and big garden, plus good neighbours bar the connecting one.
Well, I put a fairly bass heavy tune on and had the music at a level slightly louder than I would normally, which was high 60s dB (thank you for the tip Adrian). I popped downstairs to speak to the neighbour below me, he said he couldn't hear a thing and never has, result! I asked if he could hear the bass thump and he said not at all. He did comment on how considerate it was of me to ask, I'm glad I did as it's more enjoyable to listen to music without worry.
All's well that ends well.
Thanks to all for your input, it was much appreciated
Rich.
Good news.
Yes,great result! It's good to be considerate of your neighbours.
I have no problem with mine.They even throw bricks through my windows so they can hear it better!
:lol:
I found first generation air inflated Townshend
audio seismic sinks to be excellent at decoupling speakers from floor. I used them on wooden floors.
When spiked to floors, the bass would rattle the floors and I could feel it in my feet. Using sinks, all the vibration was absorbed and nothing transmitted to floors. Appreciate concrete is different to timber so effect may be different.

Yes Martin, but we are discussing which route the leakage may be through, and the curative treatment is appropriate to that route.
