A Novel Constant Directivity Horn

Dario Cinanni details its acoustic simulation study about high-frequency horn driver transducers. Using a novel equation that correlates the matrix of a virtual horn and measured compression driver pressure, it is possible to easily predict the absolute sound pressure level (SPL) of the real horn driver frequency response. The results showed a good match between simulations and measurements up to 15 kHz. This article was originally published in Voice Coil, December 2019.
