From the rumble of traffic to the roar of construction sites, we encounter noise pollution daily. Defined as the presence of excessive or unwanted sounds in our environment, noise pollution can lead to irreversible hearing damage. In this article, we'll explore the effects of noise pollution and provide advice on how you can minimise noise damage to your ears.
What Are the Sources of Noise Pollution?
Even everyday sounds can contribute to cumulative hearing damage over time. Common sources of noise pollution in urban environments include:
- Traffic
- Construction
- Industrial activities
- Loud music venues
Recognising and identifying potential sources of noise pollution in your surroundings is a critical step in protecting your hearing.
Careers That Put Your Hearing at Risk
Certain occupations involve especially regular exposure to loud noises, increasing the risk of hearing loss in workers:
- Construction workers
- Musicians
- Factory workers
- Airport ground staff
In these environments with noise hazards, employers are legally obligated under Malaysia’s Noise Exposure Regulation to provide hearing protection to their employees. This involves measures such as conducting risk assessments on site, providing personal hearing protectors to workers, and monitoring their hearing health.
If you work in noisy conditions, you should take proactive steps to prevent hearing loss by wearing earplugs or earmuffs while working and scheduling an audiometric test every year.
Effects of Prolonged Noise Pollution
Excessive noise exposure can damage the delicate hair cells in the inner ear, leading to noise-induced hearing loss (NIHL). This type of hearing loss is often gradual and irreversible. Additionally, it can contribute to other health issues:
- Elevated stress levels
- Sleep disturbances
- Cardiovascular problems
Generally, hearing damage can occur after extended exposure to sounds above 85 decibels. To put this in perspective, the noises on a busy road are usually at 80 to 90 decibels, while a concert can reach 110 to 120 decibels.
Early Signs of Noise-Induced Hearing Loss (NIHL)
Recognising the early signs of NIHL is crucial for seeking timely intervention and preventing further damage:
- Tinnitus: A ringing, buzzing, or hissing sound in the ears.
- Muffled hearing: Sounds may seem distorted or unclear.
- Difficulty understanding speech in noisy environments: You may find it challenging to follow conversations in restaurants or other noisy settings.
You should seek a professional evaluation from an audiologist if you experience any of these symptoms. They would be able to assess the damage and suggest hearing loss rehabilitation options for you.
How to Reduce Noise Damage
If you find yourself constantly exposed to noise pollution, here’s how you can protect your ears from loud noises:
- Use noise-cancelling protection in loud environments: These protectors, such as earplugs, earmuffs, and headphones, reduce the intensity of sound reaching your ears.
- Take breaks from noisy activities: Give your ears a chance to recover by going to a quieter area whenever you can.
- Maintain a safe distance from loud noise sources: By staying away from the noise source, you can significantly reduce your exposure to harmful sound levels and mitigate hearing loss.
More broadly, you can also support efforts to reduce noise pollution in your community, such as by advocating for quieter public spaces.
Safeguarding Your Hearing in a Noisy World
Noise-induced hearing loss is preventable with conscious effort and lifestyle adjustments. With regular noise protection and the help of a professional hearing test centre like The Listening Lab, you can safeguard your hearing health for years to come.
