Abstract
Active noise control is a technique in which unwanted
sound, noise, is cancelled by introducing controllable
secondary sources. Active noise control is applied to
various applications from active hearing protectors to
active attenuation of aircraft cabin noise. In the
selection of appropriate ANC strategy to an application,
several aspects have to be considered. In this paper,
selection of active noise control strategy and the
implementation of the ANC systems in two test cases are
presented and discussed. The first test case is active
attenuation of a moving machinery cabin, while the other
one is active improvement of sound insulation of a
double-wall structure. Simulation and measurement results
from these cases are evaluated and the selections of the
strategy in each case are validated.
