The effects of non-ideal elements and geometry on the performance of the Chelsea dipole active attenuator

In the development of dipole active attenuators it has been shown that the “Chelsea dipole” can give attenuation over a wide band. In this paper the effects on system performance of the departure of loudspeaker and microphone characteristics from the ideal case are considered. Fluctuations in airflo...

Zusammenfassung:In the development of dipole active attenuators it has been shown that the “Chelsea dipole” can give attenuation over a wide band. In this paper the effects on system performance of the departure of loudspeaker and microphone characteristics from the ideal case are considered. Fluctuations in airflow and temperature are also considered.
