Three groups of adults were recruited from the Ottawa Hospital Audiology Clinic. For Group 1, the sensitivity and specificity were 96% and 100%, respectively compared to conventional audiometry. Group 2 participants had clinically equivalent word recognition results for 96.2% of scores. For test-retest (Group 3), the mean difference for the left ear was 0 dB (SD 2.1) and 0.1 dB (SD= 1.1) for the right ear.

SHOEBOX Audiometry and a consumer app were compared to conventional audiometry in quiet, and 50 dB of noise in adults. Sensitivity and specificity were 100% and 95.9%, respectively, for identifying moderate hearing loss (40 dB PTA) in quiet. Compared to conventional audiometry 95.8% of thresholds in quiet and 91.3% of threshold in noise were within 10 dB.

SHOEBOX Audiometry administered in a quiet clinic room was compared to the results of conventional audiometry in a sound-treated room. Frequencies included 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz. A total of 95% of thresholds were within 10 dB of conventional audiometry. Sensitivity and specificity were 90% and 89%, respectively.

SHOEBOX Audiometry was validated against traditional play audiometry in 70 children and youth between the ages of 3 and 13 years. SHOEBOX Audiometry was found to have a sensitivity of 93.3%, specificity of 94.5%, a positive predictive value of 82.3% and negative predictive value of 98.1%.
