Abstract

It is important for audiologists to determine an individual’s maximum speech understanding in order to provide appropriate patient management regarding counseling about hearing loss and the patients? theoretical communication abilities, recommendations for amplification, and further medical referrals. This study was conducted to determine if acoustically modifying word and sentence tests would result in a more accurate representation of speech understanding abilities in individuals with mid to high frequency sensorineural hearing loss (SNHL). Nine adult volunteers with SNHL participated in the study. The NU-6 word lists and HINT sentences were modified by increasing the mid and high frequency energy of the recordings. Conditions included unmodified and three filters with cutoff frequency at 1000 Hz: 2 dB/octave, 5 dB/octave and 8 dB/octave. Each participant was tested monaurally in each ear under insert earphones at their most comfortable loudness level. Results revealed statistically significant improvements in both WRS and RTS values for the modified stimuli compared to the unmodified stimuli. Additionally, the increase in scores for the modified stimuli is also considered to be clinically significant. Given these results, it can be concluded that modified speech stimuli might be more appropriate for predicting aided speech understanding of individuals with SNHL.
