Android Mobile Audiometry Test

Abstract

The use of devices that can produce audio such as a pair of earphones and headphones in the maximum audio volume can cause damage to our hearing due to hearing loss. Hearing loss will affect a person's hearing quality to hear low volume or intensity. There is an Audiometry Test to check one's hearing quality whether it is still above or below the normal hearing threshold. It utilizes a special tool and is very useful for detecting a person's hearing loss early. The test's procedure is to play a tone that has a different frequency and intensity. Advancement of mobile technology makes a possibility to provide Audiometric Test on a smartphone device. This method will provide a convenience and an access rights for anyone to know early if they have hearing impairment without the needs of special devices. To find out the possibilities, we made an application by designing and testing 3 different smartphones and 4 pairs of earphones. The experimental results were tested using the Wilcoxon Signed-Rank Test to test the stability of mobile applications when using smartphones and earphones from different factories. Statistical tests are conducted to find the type of hardware that is suitable for use in a mobile application. This is done based on the availability of the hardware during the study. The sample was carried out on 30 people using convenience sampling method through Test Audiometry of mobile application. The procedure used on application of Audiometric Test comes from Mayfield Clinic standard. The results prove that the Test Audiometry application on mobile devices can run according to standard procedures. The testing results proved that the application can run as a simulation of an audiometry test. Statistic tests results suggest that a difference of the smartphones used in this testing does not have any effect on the outcome of the audiometry test result, but in-ear earphones show higher stability rate than regular earphones.
