This lecture is concerned with techniques to reduce noise ingress into naturally ventilated buildings while minimizing airflow path resistance. A combined experimental and theoretical approach to the interaction of airflow and sound transmission through ventilators for natural ventilation applications is described. It is demonstrated that a combination of sound reduction mechanisms – one covering low frequency sound and another covering high frequency sound – is required to attenuate effectively noise from typical urban sources. A method is proposed for quantifying the acoustic performance of different strategies to enable comparisons and informed decisions to be made leading to the possibility of a design methodology for optimizing the ventilation and acoustic performance of different strategies.

Electroacoustic Architecture offers a means of changing the acoustic properties of a room electronically. They are an alternative to physically variable acoustics, where acoustic properties are changed by retractable curtains and doors opening to reverberant chambers, etc. This paper will address the question of whether Electro Acoustic systems are a Green alternative to Physically Variable acoustics.
电声建筑为改变房间的电子声学特性提供了方法。可收缩窗帘和混响室的门口尺寸大小都可以改变物理可变声学的特性。此次讲座将说明电子声学系统是否是通向物理可变声学的绿色之路。

Effective designs for healthcare facilities include attention to acoustics. This session will be a survey of architectural acoustics and mechanical system noise and vibration concerns relating to healthcare facilities in the United States. Learn fundamental elements for addressing speech privacy, sound isolation, room finishes, and HVAC noise and vibration control. Topics will be organized by design phase to present a logical and cost effective approach.
