Train noise reduction system in MTR West Rail Line (Visit to MTR's Pak Heung Depot)

(MTR/Mr Raymond Wong)

The electrical multiple units (EMU) running on West Rail Line have many special features to reduce the noise. Some of the features are uniquely design for the both lines. Engineering design is a very important factor for noise control but a good maintenance regime is also important too.

The technical visit to MTR Pak Heung Depot is to experience the special noise mitigations on trains and also how the EMU is maintained to provide a total package to safeguard the noise level compliance along the West Rail Line.

Soundwalking in the Shing Mun Country Park: Viewing and Listening to the Rural Landscape
(Chinese University of Hong Kong/Prof. Lawal Marafa)

Shing Mun Country Park (SMCP) is one of the 23 country parks in Hong Kong and is located in close proximity to the urban district of Tsuen Wan. It covers an area of 1,400hectares. The SMCP is shielded by peaks and ridges on all sides providing lyrical scenery.

In this rural area, the forest plantations consists of more than 7,000 trees belonging to over 270 species native  to  Hong  Kong  and  South  China.  The  green  sanctuary  is  also  home  to  relatively  common  birds, mammals, including squirrels, wild boars, Chinese pangolins and the ubiquitous Macaques Monkeys.

The loop trail that circles the Shing Mun reservoir (see images below) provide access to unique sights and sounds  that  could  be  observed  and  appreciated  during  the  soundwalk.  The  soundwalk  will  allow participants to get immersed in the rural area in order to experience specific sounds in the environment and view the landscapes that provide a background to such sounds.

The visit will commence at 8:30am and end at about 01:30pm so as to allow participants to regroup for the afternoon sessions. Details of the SMCP can be accessed via:

Hong Kong Polytechnic University Acoustics Facilities
(The Hong Kong  Polytechnic University /Prof.  SK Tang)

The Hong Kong Polytechnic University started developing research in acoustics after it was converted from a polytechnic into a formal university in 1995.  With supports from the University, the Research Grant Council of the HKSAR Government, various sectors of the Hong Kong community and over 15 academic staffs, the acoustics group of the University has made significant contributions both in scientific research and teaching.  The current major areas of the group are building and environmental acoustics, vibroacoustics, engineering aeroacoustics and signal processing, including active control and sensor/actuator development.  Apart from basic facilities, such as the anechoic chamber and the reverberation chambers, the group is equipped with a low noise wind tunnel, laser vibrometers, beamforming facility and essential softwares.  During the visit, a guided tour and some laboratory demonstrations will be arranged.
