Abstract

The aim of this study was to develop a hearing screening measure using the Ling Six-Sound Test that would be easy to learn and use, while also being low-cost and brief. The Ling Six Sounds include /a/, /i/, /u/, /S/, /s/, and /m/. This study examined whether different people could produce the six sounds from the Ling Six-Sound Test in a consistent way, so that a hearing screening would be possible without speech and/or speaker variations affecting the screening results. Twenty adult participants (10 men and 10 women) with normal hearing produced each of the Ling sounds eight times while sitting two feet from a microphone in a sound attenuated booth. Peak intensity and average intensity were measured for all sounds. The first and second formant frequency were measured for vowels, and the peak frequency was measured for consonants. The intensity and frequency of each production was compared within subject, between subjects, and between genders. There were statistically significant differences within subjects, between subjects and between men and women; however the differences may be large enough to affect the outcome in a clinical setting. The results from this study indicated that a future study should be conducted with a larger sample size in order to confirm these results.
