The Effect of Plosive Content on the Loudness Perception of Vowel-Consonant-Vowel Syllables in Listeners with Sensorineural Hearing Loss
Objective: This study investigated whether plosive consonants carry a perceptual loudness weighting that significantly exceeds that of non-plosive consonants when judged by hearing-impaired listeners. Design: A prospective loudness matching experiment utilizing the method of adjustment. Study Sample: 19 consenting native English speakers (Mean age: 61.4, SD: 16.4) with bilateral mild to moderate…
The study examined if plosive consonants produce a louder perceived sound compared to non-plosive consonants among individuals with sensorineural hearing loss. Researchers employed the method of adjustment in a loudness matching experiment. The participants were 19 native English speakers, aged around 61, experiencing mild to moderate high-frequency hearing loss due to aging.
Thirteen nonsensical vowel-consonant-vowel syllables were used, all with the vowel /u/. The results showed no significant difference (P = 0.94) in loudness between plosive-containing and non-plosive-containing VCV syllables. However, six individual VCV syllables containing various consonant types showed significant loudness matching data (P).
