Accelerometer low pass filtering and high pass filtering - same as sound engineering?

Question

Are low-pass filters and high-pass filters essentially the same when referring to accelerometer algorithms as when referring to sound engineering (audio processing)?

In sound engineering, a high pass filter cuts out the low frequencies associated with the bass sound, whereas low pass filters cut out high frequencies associated with treble sounds.

I want to understand what these filters are when applied to accelerometer data and how they are used, and am wondering if there's a parallel with the physics of sound. It's all physics, right?

If they are linked in some way that might allow me to understand how to measure accelerometer movements quicker than learning it from scratch.

Thanks

Yes, the concepts are exactly the same. If you think of frequency as how rapidly something changes, you will immediately see the parallels between filtering audio, images, sensor input - anything.

A low-pass filter will only allow relatively slow changes from its output. So any "jerkiness" in the accelerometer signal would be removed, and only the more gradual change (think overall trend) would pass.
