The test signal was one-third-octave, pseudo-random pink noise centered at the indicated frequencies. The measurement microphone was placed 6. 1 m (20 ft. ) from the horn mouth, while rotation was about the waveguide geometric apexes. These axes of rotation are quite close to the apparent (acoustic) apexes across the frequency range of measurement. [. . . ] Specifications subject to change without notice.
