It really depends on the material; are these sounds that you want to remove truly peaking at a lower level than every bit of the speech? How about in loudness or 'energy'? You need to look into the ...

Change is typically "disturbing". A sharp change of amplitude (a crash, a scream, an explosive sound, etc.) Or even sudden quiet after moderate but steady background noise will disturb some people. ...

Why do relatively small but high-frequency pressure changes cause hearing loss, but large but slow pressure changes don't?

The ear has a "high-pass" filter removing very low frequencys. If you go very fast up or down the eardrum may rupture, but it will heal. If you go slower pressure is equalized through the ...

How can I eliminate sounds below a certain threshold?

I doubt you will get an acceptable result with a simple gate setup: while you may get rid of low volume breathing sounds, it will also chop away natural endings. Noise reduction plugins with noise ...

Percent volume increase to decibels

VLC's volume to dB curve is not linear. If you increased it from 100% to 110%, that is a change of +2.5 dB. Source: I also wanted to know the dB for a given percent level, so I measured it:

What is the difference in controlling volume through the software application, the system, and hardware?

This is known as gain-staging. In a pro environment this is done by watching the meters at each stage, setting levels to give the highest signal without ever going near distortion (leaving headroom). ...
