Abstract
An end-fire array using five electret microphones and “bucket-brigade” analog delay lines are used to produce the desired beamwidth at 353 Hz. A half-scale model is implemented by adding two more microphones and using three redundant microphones to give the same beamwidth at 707 Hz. High-pass and low-pass filters are used in the respective array outputs which are summed to produce a constant beamwidth over the octave. The design process is repeated to produce a constant beamwidth 3-octave array. Predicted and measured characteristics will be presented.
