Abstract
A method for designing a loudspeaker excursion estimator comprises measuring an excursion-related parameter for a loudspeaker, for each of a plurality of loudspeaker input signal levels and each of a plurality of loudspeaker input signal frequencies. The method further comprises, for each of the loudspeaker input signal frequencies and based on the measured excursion-related parameters, identifying a respective loudspeaker input signal level corresponding to a target maximum excursion-related parameter value. The method further comprises determining a filter response, based on the identified loudspeaker input signal levels and their respective loudspeaker input signal frequencies, and implementing a filter, based on the calculated filter response, for generating an excursion estimation based on loudspeaker input signal levels.
