Hearing Tests Based on Biologically Calibrated Mobile Devices: Comparison With Pure-Tone Audiometry

Abstract: BackgroundHearing screening tests based on pure-tone audiometry may be conducted on mobile devices, provided that the devices are specially calibrated for the purpose. Calibration consists of determining the reference sound level and can be performed in relation to the hearing threshold of normal-hearing persons. In the case of devices provided by the manufacturer, together with bundled headphones, the reference sound level can be calculated once for all devices of the same model.ObjectiveThis study aimed to c… Show more

“…The aim of the screening was to detect possible hearing impairment and refer pupils with positive results for further diagnostic testing. Audiological testing consisted only of pure tone audiometry, which is considered the gold standard for evaluating hearing levels [53,54], but otoacoustic emissions might be a more sensitive way of detecting hearing impairment related to noise exposure. Although our study sample was rather large, it is not representative of the whole population of Polish children aged 11-12 years; it only comprised children living in the biggest Polish city.…”

“…The calibration is performed by a normal-hearing person in order to determine a reference sound level for comparison. A comparison of pure-tone audiometry hearing thresholds with the hearing threshold measured via smartphone is done in [90]. In this scenario, the comparison is done on a smartphone calibrated using bundled headphones and biologically determined reference sound levels.…”

“…Eleven studies were found on the topic of "apps for audiometry" [16][17][18][19][20][21][22][23][24][25][26]. They mostly evaluated apps comparing the audiometric function of the smartphone with usually performed tone audiometric tests [16][17][18][19][20][21][22][24][25][26]. Only one publication mentioned an app for a speech audiometric test [23].…”

“…However, the smartphone was sometimes used in the free field so that the accuracy was limited [17]. Other authors reported a high accuracy of smartphone apps [16,20], especially when earphones were used [22]. A professional setting for the application of the user software reached a higher degree of accuracy compared to a setting selected by the user [16,20].…”
