Mr Zaqy Mohamad asked the Minister for Transport
a. whether the Ministry has studied the noise decibel levels caused by MRT trains passing through Keat Hong Crest and Keat Hong Pride;
b. if so, whether these levels exceed the 65-decibel level that is the threshold for noise disturbance under NEA guidelines; and
c. what are the criteria for the estate to qualify for noise barriers.
Reply by Minister for Transport Khaw Boon Wan:
1. LTA's preliminary finding suggests that the noise level at the blocks nearest to the MRT lines is lower than NEA's recommended threshold of 67 decibels (averaged over an hour). However, we will be doing a more in-depth island-wide study. For the installation of noise barriers, LTA will prioritise areas where the noise level has exceeded 67 decibels (averaged over an hour).
