Lower report (quieter) shotshells

We small game hunt a place that is close to (but outside city limits)
As time goes on its getting more and more built up. But it is good place to hunt.

Here's my question........does anybody know of a 12 gauge lead or Steel shotshells that is somewhat quieter than normal shotshells????

I am just trying to not BOOM out the area when we shoot so as to not wear out our welcome.....

It would be nice if they made some "subsonic" type loads similar to the rim fire loads that are not as loud.......

Thanks for any ideas
