Comparative Analysis of the Test Results of Tinglibao APP and Pure Audiometer

Objective To evaluate the accuracy of the Tinglibao APP test by comparing the results of Tinglibao APP with a pure audiometer in a soundproof room.Methods A total of 43 volunteers(22 males and 21 females)with 86 ears(35 were normal hearing and 51 were hearing loss)were included in this study.The average age was 40.9±14.5 years old.Using Tinglibao APP test software every subject performed pure tone threshold tests of each frequency at 0.125,0.25,0.5,1,2,4,8 kHz in a soundproof room environment with noise less than 30 dB A.Then the audiologist used a GSI-61 pure tone audiometer to test the same frequency threshold in a soundproof room with a noise less than 30 dB A.The differences between each frequency threshold were compated.Results The difference between APP test results of all subjects and pure tone audiometers at the frequency thresholds of 0.125,0.250,0.5,1,2,4,8 kHz were 2.50±5.66,2.15±5.10,0.87±4.54,1.09±5.40,4.59±6.37,1.86±5.87,6.69±9.02 dB,respectively.Among them,the difference between the frequency thresholds of normal hearing ears were 2.57±4.35,3.00±4.15,1.86±4.64,3.69±6.20,5.43±6.42,4.71±6.02,8.57±9.65 dB,respectively.Hearing loss ear frequency thresholds were 2.45±4.66,1.57±4.13,0.20±4.78,-0.69±4.45,4.02±6.89,-0.10±3.74,5.39±8.12 dB,respectively.The differences between the thresholds of the two test instruments of all subjects,normal hearing ears and hearing loss ears were compared,and the differences were not statistically significant(P>0.05).Conclusion The results are basically the same under the same test environment as the traditional pure-tone audiometer.The Tinglibao APP provides a convenient test method for hearing screening and self-testing.
