One highly recommended piece of equipment is the sE Electronics Reflexion Filter PRO Portable Vocal Booth which isolates your sound using a wrap-around partition with acoustical foam. After studying this product, I thought that I might be able to improve on the original design and out came some of the moving boxes currently lying around my garage floor.
After about an hour, I was able to construct what I thought might be a way to cut down on the volume produced during my practicing. Sound absorbent foam placed strategically within a box, surrounded by a yet large box seemed to me to be the solution, but after repeatedly sending my wife outside my window while playing, it was decided that my perfect solution fell miserably short of it intended goal.
My design was so bad, that my wife could not tell the difference between open horn and “boxed in” horn. DARN!
The next night was spent on line searching for alternative ways to reduce my noise level and in my next post; I will share with you still another brain storm of mine as we continue our search for the perfect sound deadening solution.
