A New Way to Predict Office Noise Annoyance
Open-plan offices are often criticized for being noisy and distracting. Coworkers’ conversations in particular can make it difficult to focus. Until now, most assessments of office noise have relied mainly on sound pressure level (LAeq). But sound level alone doesn’t tell the whole story. At Forum Acusticum/ Euronoise in Málaga, Valtteri Hongisto, from Turku University…

Classroom Noise: How Activities Shape the Sound Environment
A guest post by Chiara Visentin, a researcher at the University of Ferrara, Italy Background While noise sources like traffic or ventilation systems can contribute to classroom acoustics, in primary schools the dominant and most persistent sound is the students’ own activity and communication. Talking, moving, shifting chairs and desks all contribute to a highly dynamic…
