I would have to say that through loud enough subs, a low freq bass kick can easily move small objects... because it's such a low frequency, the air has time to knock something over bevore being sucked back in again... as for accelerating something forward like a car, chances are not.... but by the definition of acceleration though, if something moves, it's accelerated.

My speakers are a quite bass-heavy I think, or I just boosted the low-end a bit too much on my amplifier. When I sit behind my desk where my speakers are on I'm noticing a normal amount of bass, however, when I move back towards the back of the room the bass instantly gets extremely noticable. I can even feel it in my stomach (Well, sometimes not, depends on the volume  ).

No; if the velocity of some object changes, it's accelerated.

Well yah... so if something's stationary, then it moves, it's velocity has changed, therefore it has accelerated... it's simple logic

I just moved to another city and when I played back my well known songs, I was very surprised of how they sounded! Like a completely different mix!
...
Have you experienced this aswell?
|
Oh yeah, it happened when I changed my set of loudspeakers and my set of headphones. Now I use 2 Edirol MA-15D loudspeakers and AKG K-55 headphones, so nothing sounds like it did back in 1999
Btw, which city did you move to? Stockholm?
|
I moved to Västerås. 100 kilometers from Stockholm.

If something is already in motion in a vacuum, but has an unchanging velocity, it's not accelerated.
I suppose reference points start to matter here. But MEH i'm being a douchebag pedant

but our example was that there was a stationary object in front of a speaker... and if the speaker had a low enough bass coming out of it at a significant volume, the object WOULD accelerate if it moved at all... becuase it's velocity changes from vitually none, to some... which is by definition, an acceleration.

nah, thats not true. Because the velocity and thus de acceleration would both be negative and positive, and when you combine them you'll end up on 0 acceleration. Hence, there is movement, but no velocity and acceleration.
New song again. I hope you'll all like and download it. (2108 hits) |

Uh... you're muddling time-averaged quantities with real-time quantities. Just because something vibrates doesn't mean there is 0 acceleration. It's accelerating all the time - as it resonates from peak to trough of it's movement, it's under a constant fluctuating acceleration, which is why it resonates. If anything, high-frequency resonance is due to extreme acceleration, merely because to move something in a very short period of time, the acceleration has to be VERY high (more examples available on request).
Now, as to why the thing resonates at all, it may be due to Helmholtz Resonance, which is basically whole-air-movement resonance in a cavity, that cavity being the bass cavity. This causes an effect on the surrounding air just outside of the speaker, which is then also subject to similar resonance, but quickly diminishing in strength with respect to distance from the speaker.
