Play recorded sound at different levels of sound

Hi @Ravnr 

@SteveG_AudioMasters_ is correct.

So, if you want to play recorded sounds at different levels, you will need an amplifier and speakers able to create those volumes.

How do you know the level?

You will need a sound level meter which is accurate.

It is common to measure this at 1m from the sound source.

You might use a physical handheld device or perhaps a phone app.

These numbers are meaningless as far as Audition goes. Audition has a peak level reference of 0dB and whilst you can alter levels relative to that, this means nothing in terms of actual replay levels - they depend entirely uppon where your volume control is set! That 0dB is simply the point at which the system overloads, and has nothing to do with a sound pressure level at all.

Just using the term 'dB' is in itself meaningless - decibels are only ever a relative measurement until you specify a reference standard. There is a tremendous amount of mis-information around about this, but you'll get nowhere unless you have a basic understanding of the concepts behind their use. Have a look at this for instance, especially the bit about standard reference levels. To achieve these at all accurately in a playback situation you have to calibrate your replay apparatus, and that's an acoustic calibration - requires some specialist equipment.
