2. 2 Questions W2 Do you have difficulty hearing, even if using a hearing aid? B1.8How much difficulty did you have in hearing someone talking on the other side of the room in a normal voice? (take into account hearing aids, if you use them) B1.9How much difficulty did you have in hearing what is said in a conversation with one other person in a quiet room? (take into account hearing aids, if you use them)

16. 16 Results Summary World Health Survey Questions on hearing that included thresholds were more sensitive. In general, WG Q showed good specificity but low sensitivity. WG Q indicated higher sensitivity and lower specificity among older age groups

17. 17 Results Summary (cont.) Fiji and Philippines have much lower sensitivity scores W2 is significantly and moderately correlated with B1.8 and B1.9 B1.8 and B1.9 are significantly and highly correlated with each other
