An MRT worker who works for nine hours a day complained about the loud noise coming from the trains. The Shin Min Daily News reporter then conducted a decibel metre test to determine the noise level in the trains. The result was alarming. The trains were averaging over 115 decibels, which is three decibels higher than the noise level in the surrounding area.
MRI scanners
While MRI scanners are considered safe and painless, their noises can be annoying. Unlike X-ray machines, MRI scanners are extremely loud. The sound comes from a powerful magnetic field that is produced by the machine. The field created by an MRI scanner is about 60,000 times stronger than the earth’s magnetic field. For reference, the earth’s magnetic field is about 0.5 gauss. MRI scanners produce fields of around three Teslas, which is equivalent to a thousand gauss.
An MRI scanner is a large, streamlined tube with powerful magnets. It produces high-resolution images by focusing on different parts of the body simultaneously. MRI brain scans look a lot like MRI scans of other body parts. Although the noise is unbearable for most people, it may not be so unbearable for some patients. A patient may choose an open-bore MRI system if they are very sensitive to noise or suffer from migraine headaches.
MRT trains
One of the biggest complaints made by MRT workers is the noise from the MRT trains. Some trains can be as loud as 85 decibels. Long-term exposure to this level of noise can affect people’s hearing. Luckily, SMRT has begun taking steps to make the trains quieter. It is also doing track maintenance to improve the tracks’ smoothness.
Residents have also raised the issue with MRT Corp and the Land Public Transport Agency (LPA). Residents want noise-absorbing devices installed beneath the viaduct. In addition, they want double-glazed windows to prevent noise from reaching their homes.
Viaducts
The sound of MRT trains can be extremely loud, especially when they pass through tunnels or are underground. The system is trying to minimize this noise by implementing noise barriers, which are designed to keep train noise at reasonable levels. This will help reduce the chance of hearing loss, as well as improve the quality of service. While this may not sound like much, the benefits are huge.
The MRT trains produce a noise level between 80 and 85 decibels. Long-term exposure to this level of noise is harmful to the ears. The LTA has installed barriers to lower the sound level by five to ten decibels. However, some people are still uncomfortable with the noise level.
Mobile noise shields
Whether you’re a commuter or a business owner, MRT train noise can be very annoying. Its roaring noise can damage your hearing, especially if you’re exposed to it for long periods of time. The LTA is currently exploring ways to reduce the noise of their transport infrastructure. These include using concrete sleepers and noise-dampening wheels. However, this is a slow and arduous process. Moreover, no amount of soundproofing can completely eliminate MRT noise.
Mobile noise shields can make mrt noises more bearable. The REM cars have significant noise impact and are required by law to have noise mitigation measures. These noise shields are constructed of 100% PVC prefabricated panels mounted on galvanized steel posts. They also contain acoustic insulation that absorbs sound and prevents it from bouncing off of them.
Regular maintenance
Regular maintenance is essential for railways to remain in good condition and ensure a smooth commute for passengers. Without regular maintenance, it would be impossible for the railways to continue operating. Investing in routine maintenance would save more money than the cost of replacing failing equipment. In addition, regular maintenance helps ensure that the tracks are safe to ride.
At Bukit Batok MRT station, a 76-year-old employee has been complaining that the MRT trains are getting louder. She says the noise is so loud that it is like an earthquake. She also says that the frequency of trains is higher during peak hours. The noise is affecting her job performance and causing headaches.
