Contralto Audio and Rat Sound Systems are glad to announce the Engineering Brief on ‘Influence of Horn’s Surface Temperature on its Directivity Control’ at 145th AES Convention, NYC

Saturday, October 20, 10:15am — 11:15am • Jacob K. Javits Convention Center

Horn directivity control and dispersion angles, especially at high frequency, have always been achieved by carefully design and optimized the horn’s surface. It can be experimentally demonstrated that the control properties of constant directivity, high-frequency horns may be influenced by the horn’s surface temperature which can be severely affected, for instance, by being exposed to direct sunlight. This e-brief presentation shows various experimental results that demonstrates the phenomenon and shows how much this problem can influence the directivity control at high frequency range.
