• Noise generated from the traction machine may cause noise disturbance to nearby residents. It mainly comes from the noise from motors, mechanical noise of geared systems, and noise from brakes.
• Vibration from the vibration impact of the traction machine may be transmitted through building structure at points where the machine is rigidly fixed to the structure without proper isolation. The vibration transmitted may activate the building structure to generate noise which causes noise disturbance to residents nearby (see Figure 32).
(Noise Reduction Up to 10 dB(A))
• Use anti-vibration pad or vibration isolator (see Figure 34, Figure 35) and floating floor between the vibrating machines and the fixed building structure to avoid structural vibration transmission
• Provide an inertia block with vibration isolators to support the vibrating machines.
(Noise Reduction Up to 20 dB(A))
