Analysis of Directivity Anomalies in Mid and High Frequency Horn Loudspeakers

Document Thumbnail

The directional properties of horn devices are governed by the wavefront's shape presented at the mouth. An analysis of the sound pressure distribution across the horn's mouth that could certainly be helpful to understand how the wavefront is shaped there. Moreover, this could help to understand what happen in some particular circumstances. Midrange beaming or high frequency mouth diffraction phenomena for example, are two well-known obstacles to overcome designing a broadband constant directivity horn. The method forwarded by us in the previous work is here extended to some different cases and improved in the data processing. The results that come out of such analysis will be shown through graphic illustrations. Presented will be the results obtained performing measurements upon real devices correlated to traditional directivity plots as well.
