Paper Abstract

This paper addresses the benefits and drawbacks of different configurations of 3 and 4 microphone adaptive arrays. In particular, broadside and endfire configurations of equally spaced and logarithmically spaced arrays are compared. The assessment is done using arrays of simple electret microphones in actual acoustic environments. Fixed and adaptive processing approaches are assessed.
