Sound advice: modelling music halls

Have you ever seen an engineer conducting an imaginary orchestra? We think of scientists working in a lab, but Professor Tapio Lokki, of the Aalto University School of Science in Finland, has spent the last few years visiting concert halls and making meticulous measurements of their characteristics. ‘Karaoke’ is Japanese for ‘empty orchestra’ – and in some ways that is what he has created to help his studies. The research could lead to improved building designs and a form of audio ‘Augmented Reality’ (AR).
