Noise is an everyday occurrence with which almost everyone is very familiar. We are continually exposed to many different types of sound throughout our daily lives, from the boiling kettle or your alarm clock, first thing in the morning to the air-conditioning in the workplace, the traffic alongside the stalls at lunchtime and the neighbours’ dogs barking in the dead of night. Sounds can be categorised as “good sound” or “bad sound”, which is noise. Mention the word “acoustics” however and most people automatically think of some obscure science involving very complicated concepts, formulas and electronics.
This seminar aims to reduce the mystery of acoustics and provide a basic introduction to the main concepts that are relevant to the various inter-related engineering fields within the building industries. Further elaboration will be given on room acoustics and reverberation time. We will also provide examples of the effects of sound on typical constructions such as wall cavity and metal deck roof. We will share some cases on the benefits of insulation in the wall and under the roof, and how doing so would increase the STC and reduce rain impact noise and thus enhancing the comforts of modern living.
