Project Report from the year 2016 in the subject Physics - Acoustics, grade: 3.56, , language: English, abstract: This study was carried out in order to investigate the noise level at the Ondo State School of Health Technology, Akure. Prospective study design was adopted for this study and noise level meter was used to collect data and simple random sampling technique was used. The school was divided into 4 sections which are Academic, commercial, administrative, and residential sections and a sample size of 100 was determined, the retrieved questionnaire were sorted and analyzed using tables and bar charts. During the course of sampling with noise level meter, it was noted that noise coming from the commercial section was higher than any other section and ranged between 80dB and 89dB which is above the threshold limits man can be exposed to due to the operations carried out in the section. However, at night it was measured to be at lowest level of 49dB based on the close of commercial activities around 7pm daily. In the residential section it was noted that the level of noise produced between the hours of 10am and 1pm was the lowest but from the hour of 2pm upward the noise was at its peak based on the presence of the student in their various lodge ranging between 65dB to 79dB at the academic section the noise level range between 45dB to 60dB which means that the noise levels is low at the section. In the administrative section, the noise produced was between 45dB and 50dB which means that the noise level was at the lowest level for the entire school environment. In the questionnaire people′s knowledge and perception was measured, sorted and analyzed which shows that noise level is high at the ondo state school of Health Technology which should be minimized to enhance a good and conducive environment for learning/teaching.
