Abstract
Nowadays, advanced ANC systems have been developed and
implemented. It is difficult, however, to compare them or
conclude ones quality objectively because there are not
any consistent method to measure the performance of an
ANC system. It is possible to measure the efficiency of
ANC systems with conventional methods (ISO standard) but
there are certain aspects in active noise control, which
make those methods deficient or even incorrect. For
instance, in active noise control, the attenuation
depends on the SPL and there is a limit for the
attenuation ability of the active control system. The
non-linearity of the active systems is often neglected
when different systems or methods are compared. In the
current measurement reports and articles concerning ANC
systems, the results can be reported subjectively or
insufficiently. Therefore, a method for objective
comparison between different ANC systems is needed. The
preliminary testing method for ANC systems is specified
so that different systems can be compared. The
preliminary testing method is evaluated with an
experimental control system. The parameters that should
be given with the measurement results are determined.
After the public discussion and adoption of the results,
the rating of ANC systems will become easier and will be
based on appropriate basis.
