The three stand alone shop house was about 25 feet by 100 feet about 30 feet high surrounded with lots of those wooden house with unhappy tenants. Even the sound of a few dogs barking will make everybody come out to see what was happening.
The building top floor finishing is restricted to side entrance hole.
Currently the existing entrance hole is facing the back and not towards the flying path.
Moving the entrance hole to the front will cause lots of noise to those neighbors that have never been experience hot irritating those external sound would be.
The only way to minimize the external sound volume is to switch from side entrance to top entry.
The way to deflect the sound towards the sky is by erecting a brick wall in front of the side entrance hole with an opening of about 9 feet long by about 6-8 feet wide.
This will be how I planned to change the side entry to top entry.
The tweeters will be properly placed so that all of them will be facing the sky.
