Sorry folks I've just posted on this subject but I need to cooment on=
this quote which has just downloaded:

What on earth is being recorded at 140dBA? What mic input stage will
handdle that? That's well into ear damage country. 90 dBs is very
uncomfortable, 50 dB higher is 100,000 times that sound energy level.
Your ear wax will be moving. (Not a recommended treatment)
A S/N is relevant to a recording, not a transducer. With a background
noise of 30dBs (quiet), That's a recording of a 110 dBA sound. For a
loud natural sound at 90dBA, this is asking for a noise level of
