IS SINGAPORE NOISY?
The average audio level outdoors is 69.4 decibels throughout the day, which is close to a vacuum cleaner bustling all day long, co-ordinate to a 2022 study by the National Academy of Singapore.
And that number has already crossed the National Environmental Agency's recommended limit of 67 decibels within an hour.
It also cuts uncomfortably close to the World Wellness Arrangement'southward recommended cap of 70 decibels a twenty-four hour period.
In fact, in the noisiest parts of Singapore, such every bit Serangoon, Orchard, Outram and Bukit Timah, their numbers have exceeded 70 decibels, with Serangoon topping the list with 73.1 decibels, according to the NUS study, which did 18,768 sound measurements over a two-and-a-one-half-month menses.
Fortunately, Singapore's noisier neighbourhoods don't count every bit hazardous.
"Examples would exist noisy environments such as nightclubs, construction environments or factories where in that location are noisy machines operating," said Kelvin Lee, founder of The Listening Lab.
The most mutual cause of hearing loss, said Lee, is actually age.
"The inner ear – as well known equally the cochlea – is a fluid-filled, snail-shaped bony structure in your skull behind each ear.
"These structures business firm rows of hearing hair cells that are responsible for providing sound data to your brain. The various zones of hair cells, when activated by the fluid pressure, will deliver a specific frequency of sound to your encephalon."

However, with historic period, some of these hair cells go missing or damaged, resulting in an impaired ability to hear sounds. "This is ordinarily permanent and tin simply be treated with distension devices such every bit hearing aids," said Lee.
WHAT'S MAKING U.s.a. LOSE OUR HEARING YOUNGER?
While the average outdoor noise level alone isn't probable to cost you your hearing, there is growing testify that listening to music on your handphone or music player at a high volume for prolonged periods can permanently harm it, said Lee.
And become this: Singaporeans may lose their hearing early – as young equally in their mid-40s – because of such factors, he said.
"Some of these music players can produce sounds of upward to 120 decibels, which is equal to audio levels caused by a commercial airliner taking off from a rail," he said.
"Exposure to sounds of that level for even 30 minutes can result in permanent hearing damage for the listener."
For the damage to be done, the key word here is "excessive" employ, said Lee. And by that, he means more than seven hours a calendar week at a high book.
If you were guilty of blasting your ears with heavy metal in your teenage years, you may also be paying the price for it now, said Lee.
"The excessive usage of these devices tin can stack upwardly and bring forward permanent hearing loss earlier in life."
Whether you're tuning in to a radio app, your Spotify list, or communicable up on your favourite Korean drama or playing mobile app games, a adept rule of thumb to go by is the 60/60 rule.
"Prepare the volume at 60 per cent and practice not apply it more than than 60 minutes at a go before giving yourself an 60 minutes's suspension. If you set the book at 80 per cent, shorten the continuous period of usage to less than 60 minutes," said Lee.
HUH? WHAT DID YOU SAY?
If "Huh?" has been your response to many questions, your ears may demand some looking into.
"Sometimes, the initial signs of age-related hearing loss tin can exist seen in people as immature as in their 30s and information technology typically starts with the loss of high-pitch hearing," said Dr Shih E' Ching, associate consultant at National University Hospital'due south Section of Otolaryngology – Head & Neck Surgery (ENT).

"Hearing loss tin can exist divided into different categories, such equally mild, moderate, astringent or profound hearing loss.
This tin can occur in i or both ears," she said, explaining that the hearing loss is considered significant if yous can't hear sounds softer than 40 decibels, such as bird calls and quiet library sounds, for example.
Sometimes, physical interference is the cause of hearing loss. For instance, an unusual amount of ear wax buildup in the ear canal can create a blocked awareness and decreased hearing.
"Other less common causes of hearing loss include viral infections. It can likewise be acquired by sure kinds of medications that impairment the hearing, called ototoxic medications," said Dr Shih.
THE Impairment IS PERMANENT
There is no way to reverse age-related and noise-induced hearing loss. "While some people believe in taking gingko or vitamin supplements to heave hearing function, studies have not proven whatever do good in these," said Dr Shih.
Your best bet is to avert farther exposure to loud noises.
If you're out at a lodge, stand at least 3m away from the speakers. Heading for the U2 concert? Give your ears at least 16 hours of hearing detox after – no loud music via your earphones/headphones during this period.
If you take trouble hearing in your daily life and activities, especially in group or noisy environments, get your hearing screened.
