Abstract
Noise level in public buildings where training and (or) education takes place noise level is regulated by the state Lithuania to limit of 55 dB (A). Noise level of 75 – 85 dBA can be harmful for hearing organ functioning. In this study the noise level was evaluated in Kaunas Jesuit gymnasium and Kedainiai District Krakių Mikalojus Katkus gymnasium. It was found that the noise level in both high schools during breaks in the corridors, lobby and canteens and physical education classes exceeds the HN33:2011 the maximum (Lmax) and average (LAeq) noise level of public buildings where training and (or) education is takes place. The highest average noise level (LAeq) was established during physical education classes (83 dBA) in Kaunas Jesuit gymnasium and it is harmful. In all cases estimated average noise level (LAeq) exceeds 70 dBA in the Kaunas Jesuit gymnasium. The average noise level in Krakių Mikalojus Katkus gymnasium during classes (with the exception of physical education) did not exceed the alowdible maximum noise level (Lmax) and excess of only 1.5 dBA the average (LAeq) noise level according to HN 33:2011. It was also found that the average noise level (LAeq) in Kaunas Jesuit gymnasium statistically significantly higher than Kedainiai District Krakių Mikalojus Katkus gymnasium. It is likely that higher noise level in Kaunas Jesuit High School causes more pupils both in the school and in the classroom, and the different student activities in classroom as well.
