Using acoustic retroreflection in architecture to improve rooms for speech

该项目旨在发现一种新的声学处理形式如何改善教室和开放式办公室等房间的语音音质。该项目将在房间声学中产生关于声学反向反射表面的理论、设计和效果的新知识。预期成果包括有效的声学回声反射器的解决方案，回声反射如何影响人们的声音调节和音质感知的知识，以及整合回声反射治疗以改善说话舒适性的指南和模拟工具。这应该会带来巨大的好处，包括解决教育和工作场所声学环境中看似棘手的设计难题的机会。

This project aims to discover how a novel form of acoustic treatment can improve acoustics for speech in rooms such as classrooms and open-plan offices. The project will generate new knowledge on the theory, design, and effects of acoustically retroreflective surfaces in room acoustics. Expected outcomes include solutions for effective acoustic retroreflectors, knowledge on how retroreflection influences people’s voice regulation and sound quality perception, and guidelines and simulation tools for integrating retroreflective treatments to improve speaking comfort. This should provide significant benefits including opportunities to resolve seemingly intractable design dilemmas in the acoustics of education and workplace environments.
