Horn Driver Matrix is a new horn driver simulation method. The method comprises
one driver Plane Wave Tube measurement (Real World) and one horn Finite
Element Analysis (Virtual World). With the proposed method, to
virtualize a horn driver is sufficient a compression driver SPL
frequency response PWT measurement and the horn FEA. To
achieve the correlation between FEA and measurement a new
software with a new equation inside has been proposed.
Application examples:
With this method is possible to model the horn as a sort
of mechanical cross-over towards the driver frequency
response, reducing time-to-market;
This method is useful to model SPL frequency response of
a virtual horn combined with several real compression
drivers’ response and vice-versa;
With compression drivers frequency response database is
possible to fast predict SPL of each driver with the
simulated horn, without physically building horn;
A further application of the method could be a company
website with a routine providing frequency response charts
automatically, without performing measurements.
