1.5. LIMITATIONS OF THE STUDY
Both FFVT and FFCT were conducted in an enclosed, soundproof room. This room might not have reflected the environmental noise which is present during the routine FFVT. However, this limitation is in accordance with the RCT study design. No environmental noise was involved which could have altered the intensity of sound present in the soundproof room. The examination distance varied slightly from each examiner to another. This study was compared against PTA, which itself is one of the subjective assessment of hearing. Objective hearing test that can be performed is Auditory Brainstem Response (ABR). Only a single programming language was used to create the mobile app with which the features of mobile app was not able to be compared upon.
