Hi
Can we measure S/N ratio in no laboratory conditions?
I measured all of three but values are relative.
With same gain for all on mic preamp I got different peaks:
Ela M -15db
G7 -5db
C800 -10db
When I put different gain and all of three to read -5db I recorded silence
in my vocal booth (It is not anechonic room, I hear some sounds from outside). I analyze waves in Wavelab in Global Anylysis and I saw:
Ela M -67,4db peaks, -78,6db loudness
G7 -71,2db peaks, -80,4db loudness
C800 -69,5db peaks, -78,6db loudness
On listening I have same noise on G7 and C800 but different sounding and higher noise on Ela M too different sound.
When I push mute on mic preamp I saw -92db peak.
I read about measuring with capacitor connected instead of capsule.
