Hi. Condo living, diagonal neighbour (one floor down, one unit over) heard me watching Endgame last night. We share a wall. No complaints from neighbours beside me or below me.

I see a couple of products (solutions?) on Amazon. Appreciate any advice you have:

* IsoAcoustics subwoofer stands
* Sound dampening speaker riser foam, Pyle.

I have 2 x SB-1000, SVS with SVS isolation feet. Both are on the floor. Both are a foot off the same shared wall. Technically one is over his balcony & can be moved as far as I want along an adjacent wall. The other one is likely the problem one.

Thx...

Hi,

Since you already have isolation feet under your subs, I don't believe that further decoupling the subs from the floor is likely to make an appreciable difference. I think that you have correctly diagnosed the problem: the subwoofers' proximity to the party wall you share with the complaining neighbor. Apparently, bass frequencies are traveling directly through that wall in a way that disturbs your neighbor. (Bass frequencies don't just travel through the floor, as you already know.)

If you can move both subwoofers to other walls, that might help, or it might just move the problem to another neighbor. I would try moving the sub which is directly over him to an adjacent wall, first. Perhaps you could enlist him in an experiment to determine how much that helps.

The other thing I might try, depending on the success of moving the first sub, would be to move the second one further away from the party wall. In fact, you might consider moving it quite close to your listening position. That could have the dual benefit of getting it further away from the wall, and allowing you to reduce your bass volume while still enjoying the same perceived amount of bass. Nearfield subs can help with that.

Of course, you can always experiment with lower listening levels and less subwoofer volume too, but I would try moving the subs around a bit first. You never know which walls they may excite more than others, or how much the bass may bother some neighbors more than others. I hope this helps!

Regards,
Mike

Unless the feet are junk? The stands look promising & the Amazon comments are mostly positive.

I’ll def move them around & maybe leave the stands as a last resort.

Thx for the reply....

Lots of people have problems with their noise transfering to neighbor's rooms so there are lots of marketers pushing bogus remedies. In a nut shell: they are all ineffective.

Real solutions:

1. Play your music at a lower level.
2. Reduce your bass output because that is the part that migrates through the walls the most easily.
3. Face the speakers so they do not aim in the direction of the wall which the sound migtaes through. This is only partially effective.
4. Spend lots of money making the wall thicker, denser, and chock full of top notch sound absorbing material.

The reason neighbors hear your sub has almost nothing to do with how it touches the floor so rubbery mats do almost nothing. That's a myth the marketers push to support their bogus solutions. Heck you could levitate/float your sub in a magnetic field and 99% of the problem would still be there. In truth the sound in the room's air vibrates the entire wall and that's how the sound migrates through.

There are 2 ways that low frequencies are transmitted to the structure of the building:

1. Mechanical Coupling of the subwoofer to the floor, and;
2. Acoustic Coupling of the sound pressure to the structure of the floor, walls and ceiling.

Mechanical coupling of the subwoofer to the floor can be reduced by using the type of isolators you linked to. Anothr device, and probably the most popular of these, is the Auralex SubDude. These can make a difference IF your subwoofer is shaking/vibrating/rattling against the floor. However, you already have the SVS SoundPath isolation feet, and you're still having the problems, so this type of isolation is not likely to solve them.

Acoustical coupling of the sound pressure can be impacted by reducing the sound pressure level, or by increasing the mass of the floor, walls and ceiling. Since it would take ENORMOUS amounts of added mass to reduce transmission of the bass frequencies, your only real option is to turn down the bass. You can try moving your subs to try to reduce the acoustic coupling, but I wouldn't expect huge improvements by doing this.

Your best bet might be to invite your complaining neighbor over to watch a movie.

Unfortunately @Ethan Winer didn't test for "Does the bass transferring to the next room change?", still this is one of the few objective evaluations of these products I've ever seen, and exactly as I would've thought, it shows that even in that very room there are hardly any changes, except for the fact that elevating the speaker with anything will alter the sound to a small degree.

You need to turn it down. There are two ways to do this. First is to lower the gain on the sub or in the receiver. Second is to place the subs nearfield (i.e. very close to where you sit), as end tables, or right behind your seat. Since they are closer to you, they will not need to produce as many dBs for you to perceive the output as balanced with the rest of the speakers.

A way to compensate for lower sub levels is to install transducers in your seating. Cross over at 40/50 Hz and enjoy all the tactile response your rear end can absorb.

So, after running Audyssey, how much did you bump up the sub output?

If the sound inside the room doesn't change, then sound leaving the room won't change either. I think that should be pretty obvious.

Not really.
You don't think a change in the sound of room A doesn't effect room B?
Aren't there are other factors to consider based on construction material(s), frequencies and resonance. I don't buy that explanation as a "hard fact".
Just my initial thought.

You really need to read what I wrote again. If Room A does not change then Room B can't be affected.

 

[Ratman]

Okay, I really DID read what you stated. I questioned that statement as it's not obvious to me.


Did you read and chose not to address my question?
"Aren't there are other factors to consider based on construction material(s), frequencies and resonance. I don't buy that explanation as a "hard fact".

Have fun.
