P. Granados et al., IMPROVED WHITE-NOISE METHOD IN THE EVALUATION OF LINEAR HEARING-AIDS CHARACTERISTICS, Medical progress through technology, 20(1-2), 1994, pp. 37-42
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)).
