Back to the EM-158

[Klas Strandberg <>]

I am sorry folks, but the promising EM 158 doesn't do what it says it does.=

Again, it seems to be some mix up between "mV/Pa, self-noise" and
"sensitivity".

Looking at the Primo data sheet, one can easily get the impression that
EM158 should have a lower self noise than other mic's of the same size. But=

it hasn't. It gives more mV/Pa than similar ones, but the self noise
follows the same increase of gain.

I hate this word "sensitivity". It is used in so many different ways that
one can never trust it.

Sensitivity shall be expressed as mV/Pa.
Self noise as db(A)

Period.
