Why does bass travel far

Jan 10, 15, 0 Ft Huachuca, AZ. 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.

Also the design and position of the box, windows open or closed and shit there of. Yeah its all about box size, where its at, what kind of car, all kinds of things ciome into effect when talking about this. Dec 1, 6, 14 Columbus, OH. Feb 10, 6, 17 Edmonton, Alberta.

The lower the frequency being played the longer the wavelength. How far a subbass frequency will travel is dependant on surroundings. Pro Seller. Dan W might be able to add something to this,.

So what's the technical reason for a thump-fest? Generally, the further from the stage, the more bass. Because I'm too old to stand in a mosh pit, that means I'm generally far away from the action, which means I'm subjected to more bass because lower frequencies travel further.

Heh,I havent tried myself -a bit wary of those 'plasmoids pervading the domain' and the huge voltages involved not safe for my jackass attitude About the low sound frequencies travelling better, the article Sebastian quoted suggests low frequency waves travel through panels better because the arcs of the sound waves fronts dont interfer as much along the straight surface - but wheres the difference if the surface is arced to fit the sound waves, or is far enough away for the waves to be quite parallel?

I guess higher frequencies have to accelerate and deccelerate a bend or shift in physical barriers more powerfuly than low frequency waves of similar amplitude to carry themselves through, and that power is absorbed more readily by the less elastic material. But it is rather fuzzy in my head. As for the foghorn curving round the earth rather than floating off into the ionosphere Ive no clue at all.

Last Edit : by ChiGung. Low frequencies travel farther because absorption rate is proportional to frequency.

High frequency decays much quicker since the relationship is exponential. However, the loss of sound in free air is not the most significant effect.

Also there is a relationship between the wavelength and objects that can scatter the sound. So objects have to be on the order of 7 meters or more to really reflect these long wavelengths. The two possibilities I could think up were: For some reason, sound waves at low frequencies if I remember this means a lower pitch are better at traveling through solids. I have no clue if either are on the right track, and I'd really love to know! Improve this question. Add a comment.

In either case, I can't hear them and so they're not at all annoying. If they're scattered, you'll hear white noise which is not so bad. To see this, consider the low frequency limit. Say you open up an oxygen tank in your room. This will increase the pressure not only in your room but also through the whole house as it escapes. Scattering doesn't change the frequency of a wave, so it can't change a spectrum that isn't white noise into a white noise spectrum.

Because the Hz wave is Hz wave enlarged by factor of 10 The wall moves 10 times faster and for a 10 times longer time, and the displacement of the wall is times larger, when the frequency of sound is 10 times lower.

It doesn't matter if you get it, we need to get it :- and why would bass have more raw energy - certainly not true for EM waves It's intuitive that bass physically shaking a wall will pass its energy further than frequencies that make smaller molecular movements due to less "oomph.

The earthquake moves a lot more mass. I think comments about "small particles" in the wall vs wavelengths are confusing, since you could go down to the atomic level with that angle.

This is something that really needs diagrams or animations. Call that my ghetto explanation. I'll leave the details to others! In fact, it's quite a bad measuring device personal.
