Soundproofing a Bedroom window.

Lowest note on standard tuned guitar is 82.4 hZ, so cutting below that should do minimal damage - as always in these cases, your ears should be the last authority... Steve

I do have a question, however. Most of the noise that gets in now tends to be near the bottom of the human audible frequency range. Is there any disadvantage to applying an EQ cut below 100Hz to screen any remnants of those sounds out of my recordings of say, acoustic guitar? The noise tends to be mostly around 20-30Hz or even lower according to my sound leve meter.

The problem is that filters have a phase shift that occurs above its passband. Figures 11 and 12 in Ranenote 122 Show this shift. So, as Steve wrote above me, with the lowest note on a guitar being 82 Hz, a filter would need a knee atound 42 Hz to avoid shifting the musical notes.

If your frequency analysis is correct, no problem.

I hope not to technical;
