Classroom Acoustics Session at ASA meeting in Salt Lake City
Dr Siu-Kit Lau and Prof Shiu-Keung Tang have chaired a session of Classroom Acoustics at the 171st Meeting of Acoustical Society of America in Salt Lake City on 23-27 May 2016. During the meeting, Prof Tang and Dr Lau presented a paper entitled “Cantonese speech intelligibility tests in two Hong Kong primary school classrooms”. Abstract of the presentation can be found at this link. A preliminary observation is that there is higher probability for the pupils to give wrong answers when the sound of a character lasts for relatively long duration, especially when there are abrupt temporal changes in the time-frequency spectra. Correct answers are usually given when the corresponding time-frequency spectral energy is more concentrated within a short duration.

An impedance-mobility model of acoustic metamaterials
A fast prediction method for the performance of stacked membrane-type metamaterials has been developed using An impedance-mobility model. Matthew Blevins of the University of Nebraska-Lincoln introduced the method and a Matlab platform regarding this approach at the Spring 2015 meeting of Acoustical Society of America. The work is collaborated and supervised by Dr. Siu-Kit Lau and Dr. Lily Wang. Metamaterials are man-made materials to have properties that have not yet been found in nature. Membrane-type acoustic metamaterials have been proven to exhibit high low-frequency transmission loss despite their small thickness and light weight. The efficient model based on the impedance-mobility can be used to facilitate design and optimization of stacked membrane-type acoustic metamaterials.

The 11th International Conference on Green and Energy-Efficient Building & New Technologies
The 11th International Conference on Green and Energy-Efficient Building & New Technologies and Products Expo has been held in Beijing on March 24 and 25. Dr. Siu-Kit Lau has been invited for a speech regarding the current research at classroom acoustics in China. Results have been compared with a recent study in UK. There are other professionals sharing their studies and experiences in green campus development.
Meeting of Acoustical Society of China 2014
Meeting of Acoustical Society of China has been held in Nanjing on November 28th to 30th, 2014. Dr. Siu-Kit Lau has provided a presentations of classroom acoustics during the meeting.

The 21st International Congress on Sound and Vibration in Beijing
The 21st International Congress on Sound and Vibration (ICSV 21) has been held in Beijing, China from July 13-17, 2014. Dr. Siu-Kit Lau has presented a study of the acoustic comfort in the hospital of Palomar Pomerado Health (PPH). The study has evaluated the effects of flooring and ceiling choices on controlling “corridor activity noise” in an occupied hospital. Before the meeting, we had a gathering with Prof. Jian Tian (Chairman of ICSV 21), Prof. Jian Kang (University of Sheffield), Prof. Joseph Lai (University of New South Wales), Mr. Maurice Yeung (HK-EPD), Dr. Siu-Kit Lau and many others.

Acoustic Aspect in Green Buildings
Dr. Siu-Kit Lau has been invited for a presentation in a visit to the China Energy Conservation and Environmental Protection Group (中国节能环保集团公司) on June 3, 2014. The presentation has discussed Acoustic Aspect in Green Buildings. The faculty and students from the University of Nottingham as well as staffs in the China Energy Conservation and Environmental Protection Group were attended.

Thanks for the invitation from Prof. Tong Yang from the University of Nottingham-Ningbo Campus (UNNC) for a presentation of classroom acoustics to his colleagues and students on April 30, 2014. Dr. Siu-Kit Lau has a very good discussion with the professors and students in UNNC. He has visited their Centre for Sustainable Energy Technologies (CSET), which is the first “zero net energy building” in China (see photo), and also the facilities in Mechanical, Materials and Manufacturing Department. UNNC have a good team and facilities for green building research and education, as well as for acoustics. Dr. Lau also enjoyed his discussions with Profs. Rosangelar Tenorio and Dunant Halim.
