Fine-tuning the acoustics of libraries at colleges and universities

Abstract

New technology and changing student work habits challenge academic libraries to accommodate different types of study by designing different rooms for distinct purposes. This requires not only a variety of technologies, room setups, and seating, but also acoustic conditions that stimulate efficient and comfortable productivity—whether with computers, textbooks, or interactive study groups. Acoustic recordings were taken in 13 different ‘‘favorite’’ rooms, with diverse characteristics and personalities, within the two main libraries at Cornell University. The acoustic measurements were compared with observations of student activity within these spaces to determine relationships between acoustic measurements and student behavior. Factor analysis revealed three types of student-activity categories: quiet concentration, relaxing and socializing, and computer use. The analysis also revealed three categories of room type: quiet study rooms, rooms with computer use, and cafés. These categories of activities and room types correlate with acoustic measurements, pointing to the existence of distinct niches within the library system. Examining the acoustic conditions conducive to certain activities may help future designers of academic libraries to optimize the acoustics of study spaces for different purposes.
