Hearing loss is an important health care concern. Pure Tone Audiometry (PTA) is considered Gold Standard for audiometric evaluations though, there exist a huge variance between the demand and the actual services available. As smartphones are mobile, applications are upgradable, results are reproducible, the mobile applications may offer a good screening tool, especially in remote areas. There are many smartphone-based hearing applications which are already in use. However, effectiveness of such applications needs to be validated. To evaluate the reliability of 'Hearing Test' a phone application against PTA for assessment of hearing thresholds in adults. We conducted a diagnostic study on a heterogenous group of 250 individuals irrespective of their hearing levels. The hearing thresholds for both ears were measured by PTA and phone app and then compared statistically. The agreement between the methods were statistically significant with respect to diagnosing hearing loss and the degree of hearing loss. Though, PTA remains Gold Standard for hearing evaluation but freely available, highly reproducible & specific 'Hearing Test' application could be used as a screening tool in remote areas and may help bridging the gap between the requirement and availability of diagnostic audiometric services.
