Thanks all for your comments as it does make me feel like I am not being too culturally insensitive on this issue.

The kids are certainly asked to play quietly although as we all know it is a struggle but the trampoline is used say 30min per day and certainly not at inconvenient times.

Thanks also for the comments about possible rules.

I have since found out that the pace we live is about 30 years old and was a haven for small kids when first built and now we are getting a generational change as the first residents are getting old and the newer residents are moving in with kids.

Cheers
