I play jazz trumpet. I have young kids who want to sleep when I want to play. I want to play in my house, not outside or in my van.
But I have an advantage - a house with 2 foot thick walls & a small storage room in which I could play. So have built set of 2 doors with layers of plasterboard/wood/MVL/greenglue (each weighing 150lb).
Now enough sound is absorbed that its just quiet enough outside the room whenI'm inside playing.
But what I hadn't thought about is how loud it is in the room itself - with lots of sound reflections - and that's before I even think about playing backing track with rhythm section, or clear out the junk in the room which must be absorbing some sound,.
So I'm now thinking I need to build a sound absorbing box which I can point the end of the trumpet into while I'm playing.
And I figured the DIY bass box might be a place to start
Dennis - what do you think?

Hi Dave,

You need to address two sound fields. You must first lower the RT-60 (reflection) times in your room. RT-60 and noise transmission are directly related. If you lower RT-60 in the room, less energy will be present above 125 Hz. to leave the room. Work with your room first.
