Abstract
The expressions for the throat impedance of a horn with two rates of exponential flare have been derived. This expression is applicable to any number of sections by considering two sections at a time. The impedance-frequency characteristic of specific multiple horns shows the possibility of obtaining a large variety of impedance characteristics suitable for improving the efficiency characteristic over that possible with a single rate of flare. The efficiency of a horn type of loud speaker having a horn with three rates of flare shows an efficiency within a few per cent of the ultimate efficiency.
