Abstract (en)
[origin: US2004218771A1] A method for producing an approximated partial transfer function can be used in an electroacoustic appliance for producing an environment correction transfer function that matches an appliance transfer function for the electroacoustic appliance to an acoustic environment, by a) providing a number of basic functions, which each have one basic characteristic of a spectral profile of partial transfer functions, b) providing the approximated partial transfer function by combination of the basic functions weighted by weighting factors, in that at the weighting factor is in each case determined for each basic function such that operation of the electroacoustic appliance is matched to an acoustic environment taking into account the approximated partial transfer function which is formed by the weighting factors and the basic functions, and c) storing the approximated partial transfer function in the electroacoustic appliance for use during operation.
