A single wavelength can go through a window, or door and enter back in through another window in a different room. They can go around walls and corners. They can also create resonance with large objects like walls, and this helps them to pass through because the wall is facilitating the wave by matching it's frequency. Plus, as was said, bass is usually cranked out with a lot of energy for the human ear to hear.
The lower the frequency, the more energy needed. That's why down shooting sub-woofers tend to work. A normal loudspeaker would sound terrible pointed at the floor.
The sound would either get reflected off a hard surface, or absorbed by a soft surface, or both. Hope that helps. The bass has longer wavelengths. Hence there is a huge probability that the particle velocity ,at the time it hits the wall, is large.
The momentum transfer takes place at the wall interface. Hence it travels without much attenuation. Think about what happens when a soundwave "hits" a wall. Really what that means is that there's a high pressure area on one side of the wall normal pressure on the other followed by that high pressure area becoming a low pressure area. So while the sound wave's pressure is high, the air is pushing the wall, causing it to move a bit. This stretches the elastic mediums within the wall like pushing on a block of jello.
Eventually these elastic forces cause the far side of the wall to move, which pushes on the air on the other side, transmitting the sound. When the low pressure region hits, the elastic energy pushes the wall back towards this low pressure area. Once again, this transmits the sound to the other side. For low frequency sounds this is most of the story. The movement of the wall is relatively fast compared to the period of the sound wave.
For high frequency sounds, however, it gets more interesting. With high frequency sounds, the low pressure trough might occur while much of the energy of the sound wave is still propagating through the wall the jello is still squished, and hasn't had a chance to release outwards towards the other side. Now the elastic energy in this wall is "happy" to go in any direction, so when the low pressure wave starts to form in the air, some of the energy put into the wall in the high pressure phase doesn't ever get through the wall.
It is instead "put to work" pulling the wall back to its original shape. In general, this process has a tendency to invoke the non-ideal properties of the wall. It is not perfectly elastic. Some of that energy gets converted to heat. Search Advanced search…. Everywhere Threads This forum This thread.

How far does bass travel? Thread starter luvinthebass Start date Dec 6, JavaScript is disabled. For a better experience, please enable JavaScript in your browser before proceeding.

I believe and please correct me if i am wrong SPL levels which are vary from subject to subject.
I do know it has to do with keeping more coils in the cap creats a higher spl rating which is why RE has XBL2 on alot of subs.
