Language Familiarity in Magnitude-Estimation Scaling of Loudness by Young Adults

Abstract

The purpose was to examine the effect of language familiarity on magnitude-estimation scaling of loudness by young adults. Two groups of subjects participated in this study. Group 1 of 20 subjects (M age = 23.95 yr.) were familiar with English and not familiar with Hindi. Group 2 of 20 subjects (M age = 24.30 yr.) were familiar with English as well as Hindi. Two separate magnitude-estimation scaling tasks were performed. On the first scaling task, an English sentence was used as the stimulus, and on the second scaling task, a Hindi sentence was used as the stimulus. Statistical analysis showed that there was no significant difference between the two groups in loudness judgments of the English and Hindi sentences. Subjects scaled the loudness of an unfamiliar language in the same manner as they scaled the loudness of a familiar language. The findings suggest that magnitude-estimation scaling is an effective measure of loudness whether the language being listened to is familiar to the listener.
