Study of the Intensity of Sound and Light in Faculties of Babol University of Medical Sciences

Light and brightness are the first environmental factor for any type of activity. The other physical factor that has been considered in recent years is sound. Noise/sound and light can affect the quality of human performance. Therefore, the aim of this study was to evaluate the intensity of light and sound in the Faculties of Babol University of Medical Sciences.

Among 4 selected faculties, 25 classrooms and 25 offices were randomly chosen. The intensity of light was measured (both natural and artificial). The light level was measured using the S724997 device, whose metering sensor was mounted at a height of 24 in. (60 cm) from the floor. Sound was measured in classrooms during two periods of the presence and absence of students and university staff members. The sound level was measured using a sound level meter (SLM). Data were analyzed using SPSS 22.

The mean sound intensity of the classrooms at the time of the presence and absence of individuals was 59.10 dB, 59.09 dB, and 48.53 dB, respectively, which was higher than the standard. The mean light intensity was 445.44 and 535.93 lux in the classrooms and office, respectively, which was standard.

The results of this study indicated that the sound level was higher than the standard at all places. The light level was near-minimum standard in most places that should be improved. Therefore, because of the importance of these two issues, the necessary measures should be taken to remove the defects.
