This study was conducted to measure the exposure levels to noise for the middle and the high school students who worn headsets in the PC rooms. The noise levels from the headsets were measured with noise dosimeters. and the statistical relationships between the utilization pattern, user’s views on the PC rooms and it’s environrnent were arialyzed for the selected PC rooms in the Ahnshan area. The results were as follows; 1. No significant difference was found in the number of uses and average time spent per day by education level and bv sex of the users(p>0.05).2. No statistical significant difference was found between the contents selected by education level of the users (p>0.05). The male participants overwhelmingly enjoyed the PC games (98.3 %) while females selected for listening music (75.0 %) with significant difference(P<0.05), followed by browsing internet and PC communications (70.0 %), PC game (66.7 %) and chatting (33.3 %). 3. The actual noise measurer-nents of the headsets worn by the users of different sexes and educational backgrounds produced no differences(p>0.05), while a significant difference was found between genders (p<0.05). 4. For sound pressure level measurements, the weighted average(Lavg) of 84.5 dB(A) on the left headsets exceeded that of 79.8 dB(A) on the right headsets significantly(p0.05), however, the contents selected by the users with different educational backgrounds were noted with significant difference(p<0.05) while no difference was found by gender(p>0.05).
