Abstract

ABSTRACT

This study examined indoor sound pressure level in selected rooms within a students’ housing neighbourhood in Nigeria; assessed the self-reported physical health symptoms of the occupants; and analysed the relationships between the two. Sound pressure level was measured in each of the randomly selected 22 rooms at 15-minute intervals between 7hours and 19hours daily through a period of four weeks each during the peaks of both dry and wet seasons. The measurement was done with Data Loggers placed at work plane at the centre of the rooms. Purposive sampling was used to select all the occupants in the selected rooms as well as the two adjoining rooms to fill a questionnaire. This amounted to 696 respondents. The questionnaire, elicited information regarding what each respondent regarded as the most prominent source of noise, their gender, age and complexion, as well as their self-reported physical health status. This study found that a significant 79% of the respondents identified indoor noise sources as the prominent contributor to the acoustic condition in the rooms; that the mean measured sound pressure levels in each room layout ranged from 27.75 dB to 56.29 dB; and that the self-reported physical health symptoms with significantly high percentage of observation were cold, fatigue, and headache. Correlation analysis showed that there was an inverse relationship between the sound pressure level in the rooms and the frequency of observance of cold, fatigue, and headache among the occupants. However, the relationship is more significant during the wet season, and more pronounced in female occupants than in male.
