Community of Sexsoundlovers

hey so I have this neighbor of mine that lives next door to me and everynight the couple be having sex like I can hear him spanking her every once in awhile and sometimes the bed squeaking as well but their window is about a few inches away from mine
so I was wondering how I can make the sounds echo by using a soup or something that will make the sound flow into a tube where I can listen to it with my ears as I tried using a vacuuming tube but the sound does'nt work as much when it flows through the tube so I was wondering if I should try a metal tube instead to where the sound will bounce back to my end as I try and keep the blinds closed as much as possible without giving them the hint that I'm listening so anyone know any tricks maybe like an alloy tube or aluminium tube or PVC pipe?

If it was me, as their window is so close to yours, I would put a USB recorder (or any other type) on my window sill and leave it recording overnight. Apart from being able to listen yourself, you could then share it with the community!
