AbstractThe designing and calibration of Ling Six-Sound Test with principles of sound field audiometry was carried out to establish normative data on ten normal-hearing adults. The Ling Six phonemic stimuli were used to test auditory detection levels. The calibration on all stimuli was completed using concatenated sound files played at 70 dB HL through one speaker of a five-speaker array. The results show that the SPL values yields the frequency distribution of each phoneme and a-weighted levels in dB SPL.
