Noise pollution is a problem in many countries around the world. In schools, exposure to noise causes a wide range of adverse effect on the health and performances of students and teachers. This study was carried out to assess the levels of noise in the various departments in the Faculty of Physical Sciences, University of Benin, Nigeria. Noise levels were measured using a digital sound level meter (Smart Sensor Model AS824) and the coordinates of the sampling locations were obtained using a GPSMAP 64x handheld Global Positioning System device. The mean levels of noise across the various offices, classes and laboratories in the faculty ranged from 47.50±1.44 (Geology) to 50.84±3.09 (Computer Science). The mean noise levels all exceeded the World Health Organisation limits of 35dBA and the NESREA limit of 45dBA for noise in educational facilities. Such high levels of noise could interfere with the learning process by reducing the efficiency of communication between lecturers and students, affect attention span and may cause a reduction in academic performances. It is therefore recommended that measures be implemented to prevent and control noise in the Faculty such as tree-planting, installation of sound insulators and raising awareness on noise and its adverse effects among the students and staff.
