AbstractThe research examined the frequency of hearing loss among college students in Johor via the use of pure tone audiometry (PTA) screening tests. The study included a sample of 30 participants between the ages of 18 and 35, with 46.67% of them using personal listening devices (PLDs) for educational reasons. The Air Conduction (AC) and Bone Conduction (BC) tests were used to evaluate the different types and levels of hearing impairment by using Audiometer, model Interacoustic AD629. This research used one (1) decibel (dB) increment for the up-and-down hearing threshold for both AC and BC measurements. The participants were categorized into two groups: the experimental group, which altered noise thresholds and daily use, and the control group, which kept their usual use of PLDs. The findings indicated that 73.33% of young adults use PLDs, with earphones being the predominant preference. Approximately 30% of the whole amount is comprised of cellphones and laptops. A substantial number of par.....
