| dc.description.abstract | This report is an investigative study of the feasibility and limitations of active noise control in a 4" I.D. duct. The study yeilded results comparable to those which were predicted theoretically. The limitations of the active noise control were defined by the dimensions of our duct. The frequencies that were discovered to be useful with our system ranged from a lower frequency of 90 Hertz to an upper frequency of 1800 Hertz. The final system which used a microphone as the signal transducer, was capable of attenuations between 10 and 29 decibels within our frequency range. | en |
