Horn loudspeakers nonlinearity comparison and linearization using volterra series
(2008) 124th Audio Engineering Society Convention 2008 1. p.57-66- Abstract
The characterization of a weakly nonlinear electroacoustic device with usual methods of measurement (THD, intermodulation) does not illustrate the nonlinearities themselves, but only some of their effects. Device linearization can be achieved by applying the inverse nonlinearity upstream of the device, under the condition that the nonlinearity law is known in detail. This paper presents nonlinearities behavior comparison of horn loudspeakers of different frequency ranges using an experimental method of weak nonlinearity characterization and compensation, based on a representation of the nonlinearity by Volterra series using multitone excitations.
