What You'll Learn
Turn off appliances when not in use
Turning off appliances when not in use is an effective way to reduce noise pollution. This includes televisions, games consoles, computers, and other devices that can create unnecessary stress on the ears when left on. By turning them off, we can also reduce our electricity costs and minimise the negative impact of noise on our health.
Noise pollution has adverse effects on human health, as recognised by international bodies like the WHO. Constant exposure to loud noises can lead to hearing damage, sleep disturbances, increased stress levels, and even contribute to cardiovascular disease. By turning off appliances, we can help mitigate these harmful consequences.
Appliances such as dishwashers, blenders, and washing machines can be particularly loud. Running them in separate rooms and shutting the door can help seal off the noise. Additionally, we can opt for quieter alternatives or noise-cancelling options when purchasing new appliances. For example, choosing a quieter model of a dishwasher or using noise-cancelling headphones can significantly reduce noise levels.
To further reduce noise pollution, we can also implement simple measures such as padding under noisy equipment, using ear protection like earplugs or earmuffs, and maintaining our machines properly. Proper lubrication and regular maintenance of appliances can reduce friction and minimise noise emissions. These combined efforts will help create a quieter and more peaceful environment.
In addition to turning off appliances, we can also be mindful of the volume levels of our devices. Lowering the volume on televisions, stereos, and speakers can make a significant difference in reducing noise pollution. This is especially important in shared spaces, such as apartment buildings or offices, where noise can easily travel and disturb others.

Use ear protection, like earplugs
Noise pollution is a serious issue, causing hearing damage and affecting our health. Extended exposure to loud noise can lead to temporary or permanent hearing loss. Noise-induced hearing loss (NIHL) is a significant problem, with one in seven US teens showing signs of NIHL in one or both ears, according to the CDC. Therefore, it is important to take steps to protect our hearing.
One effective way to protect our hearing and reduce the impact of noise pollution is to use ear protection, such as earplugs or earmuffs. Earplugs are small inserts that fit into the ear canal and are designed to lower the intensity of sound that enters our ears. They can be made from formable foam, pre-molded, canal caps, or custom-moulded to fit the individual's ear. Custom-made "musician earplugs", for example, are designed to protect hearing while allowing as much natural sound as possible to enter the ear safely. Earplugs are simple to use, often more comfortable, and less expensive than earmuffs. They are also less visible, which can be advantageous in certain situations.
However, it is important to note that earplugs may not provide the same level of noise reduction as earmuffs, especially in extremely loud environments. Earmuffs are large cups that fit over the entire outer ear, creating an air seal to keep ears safe from loud noises. They are joined by an adjustable headband and are available in sizes for both adults and children. Earmuffs are often easier to use correctly, especially for young children, but may not work as well for people who wear glasses due to potential gaps between the skull and the earmuff cushion.
When choosing between earplugs and earmuffs, it is important to consider factors such as comfort, noise level, and personal preference. It is also worth noting that hearing protectors do not block all sound, and the level of noise reduction can vary depending on the product. Most hearing protectors have a noise reduction rating (NRR), which indicates how much sound is blocked. Generally, the higher the NRR, the more sound is blocked, but it is important to refer to the manufacturer's literature for specific information.
Overall, ear protection is an effective way to safeguard our hearing and reduce the impact of noise pollution. Whether choosing earplugs or earmuffs, it is crucial to ensure a comfortable and secure fit to maximise the benefits of these protective devices.

Plant more trees
Noise pollution is a serious health concern that can have adverse effects on human health, including hearing damage, sleep disturbance, cognitive impairment in children, cardiovascular disease, and annoyance. It can also negatively impact wildlife, interfering with breeding cycles and hastening the extinction of some species.
One effective way to combat noise pollution is to plant more trees. Trees act as natural noise blockers and can significantly reduce noise levels. They achieve this through various mechanisms, including sound attenuation, which involves the damping of sound as it passes through the tree's structure. The different parts of a tree, such as stems, leaves, branches, and wood, all play a role in absorbing and deflecting sound waves. Thick, rough bark and fleshy leaves are particularly effective at sound absorption due to their large surface area. Additionally, the rigid structure of tree trunks prevents them from vibrating in response to sound waves, reflecting the waves back towards the source.
When choosing trees for noise pollution reduction, it is essential to consider the species and their placement. Broadleaf trees, such as oaks, are effective at deflecting sound, but they lose their leaves in winter, reducing their sound-blocking ability. Evergreen trees, on the other hand, provide a consistent buffer against sound as they retain their needles or leaves year-round. They are also fast-growing and can be planted close together to create a dense vegetation barrier. It is important to select trees that will thrive in the local environment and are tolerant of air pollution if planted near roadways.
The placement of the tree buffer is crucial. A buffer planted closer to the source of noise will block more sound than one planted farther away. For example, a 100-foot-wide tree buffer planted 100 feet from a road will reduce noise levels by about 10 decibels more than the same buffer planted 200 feet away. Additionally, trees with thick or papery leaves, like quaking aspen or oaks, create a pleasant rustling sound in the breeze, contributing to the masking effect, which offsets noise pollution with more appealing sounds.
In addition to their noise-reducing properties, trees offer a host of other benefits, including carbon dioxide absorption, shade provision, and soil erosion prevention. They also attract wildlife, such as songbirds and crickets, contributing to a more natural and immersive soundscape. By planting more trees, we can create healthier and more peaceful environments while also addressing noise pollution and its detrimental effects on both human health and wildlife.

Soundproof your home
Soundproofing your home can be a great way to improve your quality of life, especially if you work from home or are affected by noisy neighbours. There are a variety of methods you can use to soundproof your home, ranging from simple DIY tasks to more complex projects requiring professional expertise.
Firstly, identify the problem areas in your home. Are you trying to block out noise from the street, or are you more concerned with noise from inside your home travelling between rooms? Once you know the areas you want to target, you can choose the best soundproofing methods for your needs.
If you're dealing with noise from outside, start by tackling gaps around doors and windows. Weatherstripping can be an effective first line of defence against unwanted sound. For doors, you can also try using a door sweep to block the gap between the door and the threshold. Solid-core doors are best for external doors, and if your home has hardwood floors, be aware that these can add to the echo in your home.
Windows can be soundproofed by double glazing them or using laminated glass, which can reduce noise when sealed shut. You can also hang thick curtains to help block out noise, or try using window plugs made from recycled plastic, like Felt EchoTiles.
For walls, you can try using sound-absorbing materials such as acoustic panels, or hang rugs or tapestries to help dampen sound. A more intensive method is to add a second layer of drywall, using an adhesive like Green Glue to decouple the layers and prevent sound transmission through the studs. Ceilings can also be soundproofed using this method, with a sound-damping compound added between the layers of drywall.
If you have noisy neighbours downstairs, you can try soundproofing your floor by adding a layer of dense rubber, cork, or polypropylene underlayment beneath your flooring to reduce vibration transfer.
In addition to these methods, you can also try creating a healthier noise environment by playing music, having singing birds, or installing a small indoor waterfall.
