In order to decrease the noise level of our
fans, RAF 1600 - 2503, an in-line silencer
must be installed on the exhaust duct. Se-
veral examples are illustrated of how noise
level measurements can be aff ected. It is not
unusual to obtain measurements of up to
110 - 120 dB(A) in completely non-silenced
installations.
