Multitone and log-sweep testing signals at progressively increasing levels were applied to a horn driver to obtain a nonlinear response. Musical signals were also applied to the driver. The acoustical signal was received at the throat of the horn and at a 1-meter distance from the horn in a 2-Pi anechoic chamber. The levels of the applied signals were incremented in 3 dB voltage steps. The initial horn driver response was corrected to provide maximum flatness and passed through a high-pass filter. Auralization examples and graphic material are demonstrated. The next stage of the research will involve subjective listening tests with signals obtained from measurements and from nonlinear models of horn driver.
