Abstract
In this paper an alternative method of determining the standardized el ectroacoustical parameters for hearing aids is discussed. This is done by using white noise as the input stimulus and a high resolution algo rithm, Burg's method, to obtain the spectral estimation of the frequen cy response. Three types of hearing-aid are analyzed according to both the pure tonal and white noise method and their standardized computed electroacoustical characteristics are compared. The results show deep differences at the low frequency range and a close match at high freq uencies (HFA-ref. test and SSPL-90 dB(SPL)).
