Hi all,
I just received news my new BH got complained about the noise, but didn't say specific which part or direction.
Last week we have checked day&night both internal and external volume to be at correct levels.
I had personally tuned the internal tweeters to the 2nd lowest notch which sounded as if normal bird volume.
The external tweeters were not tuned by me, but my partners said only can hear little bit at ground floor.
Gonna make a trip there ASAP to solve this, so is there anything specific that I should lookout for ?
Maybe the timer or amp volume not accurate/consistent ?
Styrofoam + ceiling board + half closed window -> not soundproof enough ? really need bricks?
Thanks in advance...
Really paiseh disturb other ppl

Im worried if next warning come again means TheEnd for me
There are 2 main type of complaints; one is what we consider is serious and true complaint and the other is what we call, jealousy complaint.
As for the real complaint as many of BHs really need to lower their sound as it's really disturbing to your neighbors. It's not what at the volume at the amp that tell how loud the sound is as it depend on the number of tweeters and the amp. A volume notch of 3 at one amp doesn't prove anything as each amp even of the same model don't have the same output at the particular notch. Let you ears be the judge of the sound.
Open type of BHs can really create problem for the houses behind the BH esp. in the middle of night as sound seem to magnified many times in the quite night........even the sound of mosquito can be heard clearly. With your internal sound going, it can cause sleepiness night for many and that's not good for the reputation of BHs in your town. I never advice fellow BH owners to make window type entrance rather do the open air well for the town's BHs. I also advice people not to use internal sound at night and so far, none of my BHs has a internal night sound but I don't say that having one is not correct rather not to have one @ night in town BH so that all town BHs can be safe from destruction.
Out of town, do what you want as nobody will care with exception that you may disturb the wild animals or maybe some dead souls living at the area.
So, there is not such thing as the correct notch as each amp is different at a specific location. Most nearby residents don't mind the day sound but don't take kindly to the night sound. In one long ago case, we have to take action on our own to remove the TNB power fuse to solve the complaint of the resident staying behind the BH (the owner is not local).
Coming to the second type of complaint and this type is jealousy type and there isn't any way to solve as I do have a problem with it. Many years ago, behind one of my BHs is another successful BH and as all smart people, open my entrance hole to face his entrance. That is the starting of my nightmare as my back shop BH owner has been complaining secretly to the Association so many time about the noise disturbance of my new BH ever since I started the sound. The complaint doesn't even stop after I cut the connecting cable just leaving the tweeters with cut wire. That was the only time I tried with open window type entrance and since then, I promise myself never do another open window BH to save myself from any nonsense complaint.
Just my own Experience to share.
