The paper presents the evaluation of classrooms for young children in India, to assess their acoustical environments. The schools under consideration are located in an educationally advanced locality in India – a district in the southern part of India, namely Kanyakumari. Situated in a tropical climate, the classrooms have open windows and doors with the possibility of noise intrusion from outside. Schools are located in different regions to suit the conditions of education administrators and other factors, and not necessarily the best location for a learning environment. In this study, depending on the location of the schools and their external surroundings, the schools are classified into three categories: a) schools located near roads with heavy traffic (Noisy-sites), b) schools located within Housing sites, c) schools located in zones far from public roads and away from residences (Quiet sites). External and internal noise surveys have been conducted to evaluate the background noise within the classrooms. About 120 classrooms in 25 schools were selected for the study of the acoustic quality within the classrooms, based on measurements. The external noise has a very great influence on the background noise in empty classrooms with open windows. It may not be practicable for schools in tropical climates, where rooms with open windows and doors are realities, to conform to the guidelines of standards such as ANSI S12.60 or BB 93.
