Mount metal pellet traps lined with duct seal or ballistic putty on corners all inside your house to shoot across the living room kitchen bedroom and hallway. Just keep the traps away from big screen TVs or computer screens you should be fine.
AND! couple jars of color matched spackle drywall and wood putty and matching wall color touch up paint too.
The interesting thing about the Huma, you can alter the baffle or segment count. I have a single section on mine, but when you buy them, they have three total (mind did). You can buy more segments to make it even quieter.
The single section looks good, and is quiet...enough..!
