Detection of Hearing Impairment in Patients with Subjective Complaints of Hearing Loss Using the Whispered Voice Test and Standard Pure Tone Audiometry: A Prospective, Double-blind, Cross-sectional Study

Objectives: To determine the sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio, and accuracy of the whispered voice test compared with standard pure tone audiometry in detecting hearing impairment in patients with subjective complaints of hearing loss. Methods: Study Design: Prospective, Double-blinded, Cross-sectional Study Setting: Tertiary Private Hospital Subjects: 55 consecutive patients who underwent hearing evaluation via pure tone audiometry. Results: 55 subjects composed of 60% (n=33) females and 40% (n=22) males with ages ranging from 13-85 years old (Mean±SD=44.99 ± 19.19) were included in the study. 58.2% (n=64) ears responded correctly in the whispered voice test while 59.1% (n=65) had normal hearing threshold on pure tone audiometry. There was significant association between age and whispered voice test (Pearson’s chi-square=68.24, df=27, level of significance=0.05, p-value=0.000). The same significant association between age and pure tone audiometry results (Pearson’s chi-square=70.52, df=27, level of significance=0.05, p-value=0.000) was found. There was also significant association between the whispered voice test and pure tone audiometry results (Pearson’s chi-square=151.59, df=27, level of significance=0.05, p-value=0.000). Sensitivity and specificity of the whispered voice test were 93.75% and 89.13%, respectively. Positive predictive value was 92.31% and negative predictive value was 91.11%. The positive likelihood ratio was at 8.62 while the negative likelihood ratio was at 0.07. Accuracy was computed at 91.82%. Conclusions: The results in this study are comparable to those of previous studies. The whispered voice test is an accurate tool in the detection of hearing loss. It can be used as an alternative to audiometric evaluation in the screening of patients with subjective complaints of hearing loss by ENT specialists and general practitioners in the urban and rural setting.
