AB  - It is ideal to measure acoustic characteristics by point-source sound. We proposed, at previous convention, a point-source measurement loudspeaker which is designed to attach the mouse of hyperbolic horn to the diaphragm of driver unit. The difference of directional intensity of the loudspeaker at the frequency range of 20 - 700 Hz were within 3 dB at any combination of azimuth and elevation. At the frequency range over 700 Hz, difference of azimuthal directional intensity were within 10 dB while that of the elevational ones were within 20 dB. Following these results, difference of directional frequency characteristics is discussed. Then we applied the loudspeaker for the measurement of acoustic characteristics a hall.
