Results: Those using phones for 2-3 hours daily, loss of 5 dB in 10%, 10 dB in 3.3%, and 15 dB in 1.6% were noted. Also loss of 5 dB in 6.6% and 10 dB in 3.3% were noted in those using 3-4 hours daily. Sensorinueral hearing loss was seen in 26.6% of the subjects in study group and 3.3% in control group.
