Abstract
Example embodiments disclosed herein relate to modelling a frequency response characteristic of an electro-acoustic transducer. A method includes obtaining at least one measurement of the frequency response characteristic for at least one electro-acoustic transducer of the category. A model of a frequency response characteristic specific to a category of electro-acoustic transducers is generated at least in part based on perceptual importance of a frequency band, an averaged, normalized or microphone compensated measurement such that the distortion of the model is optimized. A further method for estimating a frequency response characteristic of an electro-acoustic transducer is based on the generated model and the sensitivity of the electro-acoustic transducer or headphone. Corresponding system and computer program product are also disclosed.
