Screening of hearing in elderly people: assessment of accuracy and reproducibility of the whispered voice test

Sensitivity, specificity and positive and negative predictive values were calculated and accuracy was measured by calculating the area under the ROC curve. The test was repeated on 20% of the ears by a second examiner to assess inter-examiner reproducibility (IER). The words and phrases that showed the highest area under the curve (AUC) and IER values were: “shoe” (AUC = 0.918; IER = 0.877), “window” (AUC = 0.917; IER = 0.869), “it looks like it's going to rain” (AUC = 0.911; IER = 0.810), and “the bus is late” (AUC = 0.900; IER = 0.810), demonstrating that the whispered voice test is a useful screening tool for detecting hearing loss among older people.

It is proposed that these words and phrases should be incorporated into the whispered voice test protocol.
