Protecting Your Hearing at Noisy Jobs in Brampton

Brampton’s economy has a loud side. Manufacturing plants, printing operations, food processing, warehouses full of forklifts and conveyors, construction sites, auto shops and busy commercial kitchens can all expose workers to noise for hours at a time. Add a commute along the 410 with the radio turned up, earbuds at the gym and a family celebration with music and drums, and your ears may be working harder than you realise.

Noise-induced hearing loss usually develops slowly and without pain. You might not notice it until conversations in a crowded room become hard to follow, or a family member comments that the television is always too loud. By then the damage is generally permanent. The good news is that this kind of hearing loss is largely preventable.

The pharmacy team at Pharmasave BramCity on Lisa Street can help with practical questions about ear care, earwax and products for the ears, and can point you towards the right professional when you need a hearing test. This article covers what working adults should know about protecting their hearing.

How loud noise damages the inner ear

Deep inside the ear, tiny sensory hair cells convert sound vibrations into signals that travel to the brain. Very loud noise, or moderately loud noise over long periods, can damage or destroy these cells. Once they are lost, they do not grow back.

The risk depends on both how loud the noise is and how long you are exposed. A short burst of very intense sound, such as an explosion or a nail gun right beside your ear, can cause immediate harm. More commonly, damage builds up from steady exposure over months and years, such as eight-hour shifts beside loud machinery.

After a noisy shift, you might notice muffled hearing or ringing in your ears that fades over a few hours or by the next morning. That temporary change is a warning sign. It tells you the noise was loud enough to affect your ears, and repeated episodes increase the chance of lasting damage.

Is your workplace too loud?

Workplaces in Ontario have legal requirements for managing noise exposure, which can include measuring noise levels and providing hearing protection. If you are unsure whether your workplace is too loud, a simple rule of thumb many safety organisations use is this: if you have to raise your voice to be heard by someone about an arm’s length away, the noise may be at a level that can harm hearing over time.

Ask your supervisor or joint health and safety committee whether noise levels in your area have been assessed and what protection is required. The Canadian Centre for Occupational Health and Safety has worker-friendly information on noise and hearing conservation that can help you understand your rights and your employer’s obligations.

Remember that noise does not need to be painful to be harmful. Many people find a loud environment uncomfortable at first and then get used to it. Getting used to noise does not mean your ears are not being affected.

Choosing earplugs that you will actually wear

The best hearing protection is the one you wear correctly every time you are exposed. Earplugs come in several types:

• Foam earplugs that you roll, insert and allow to expand inside the ear canal
• Pre-moulded reusable plugs, often with flanges, that can be washed
• Banded plugs on a flexible headband, handy for people who move in and out of noisy areas
• Custom-moulded plugs made from an impression of your ear by a hearing professional

Packages list a noise reduction rating, but real-world protection depends heavily on fit. A foam plug that is only pushed partway in may provide much less protection than the label suggests. Comfort matters too. If a plug irritates your ear, you will be tempted to take it out.

Getting a proper fit with foam plugs

Foam earplugs are inexpensive and effective, but many people insert them incorrectly. With clean hands, roll the plug between your fingers into a thin cylinder. Reach over your head with the opposite hand and gently pull the top of your ear upward and back to straighten the ear canal. Insert the rolled plug and hold it in place for several seconds while it expands.

A well-fitted foam plug sits mostly inside the canal. Your own voice should sound deeper and louder, and outside noise noticeably quieter. If much of the plug is sticking out, remove it and try again. Replace disposable foam plugs regularly, and do not use them if they are dirty or have lost their ability to expand.

Earmuffs and combining protection

Earmuffs cover the whole outer ear and can be quicker to put on and take off than plugs. They work well for people who move between quiet and noisy areas. Their seal can be broken by safety glasses arms, long hair, hats or a beard, so check the fit. Replace cushions when they become hard or cracked.

In very loud environments, some workers use earplugs and earmuffs together. Your workplace safety program should advise whether that is required. Never modify hearing protection, for example by drilling holes in earmuffs or cutting earplugs, as this reduces protection. Store earmuffs somewhere clean rather than tossed in the bottom of a toolbox, and check the headband still holds the cups firmly against your head. A band that has been stretched over a hard hat for months may no longer give a good seal.

If you need to hear warning signals or communicate with co-workers, ask your employer about protection options designed for those situations.

Earbuds, music and noise off the clock

Hearing does not reset when you clock out. Personal listening devices are a common source of extra noise exposure. On a loud bus or in the gym, it is tempting to turn the volume up to drown out the background, which can push sound to risky levels.

Noise-cancelling headphones can help by reducing background noise, allowing you to listen at a lower volume. Many phones have settings that warn you about loud listening or let you cap the maximum volume. Give your ears quiet time after a noisy shift rather than going straight from machinery to loud music.

Loud hobbies such as power tools, motorsports, concerts and some celebrations count too. Keeping a set of earplugs in your car or bag means you can protect your ears when you find yourself somewhere louder than expected.

Earwax, hygiene and ear canal care

Wearing earplugs every day can sometimes contribute to earwax build-up or irritation in the ear canal. Earwax normally works its way out on its own and does not need to be removed. Avoid cotton swabs, hairpins or other objects inside the ear, which can push wax deeper or injure the canal.

If your ears feel blocked, itchy or uncomfortable, ask a pharmacist before using any earwax product. Some products are not suitable for people with ear tubes, a perforated eardrum, ear pain or discharge. Keep reusable earplugs clean and dry according to the manufacturer’s instructions, and do not share them.

Some people develop itchy, red or flaky skin around the outer ear from constant contact with earmuff cushions or plug materials. If that sounds familiar, the pharmacist can talk with you about skin irritation and dermatitis and whether a different style of protection might be gentler on your skin.

Signs it is time for a hearing test

Book an assessment with your doctor or a hearing professional, such as an audiologist, if you notice:

• Asking people to repeat themselves more often
• Trouble following conversations in noisy rooms or on the phone
• Others commenting that your television or radio is too loud
• Ringing, buzzing or hissing in your ears that persists
• Hearing that seems worse in one ear than the other

Seek prompt medical care for sudden hearing loss in one or both ears, ear pain with fever, discharge from the ear, or dizziness. Sudden hearing loss is treated as an urgent problem. Some workplaces offer regular hearing tests as part of a hearing conservation program; ask your employer whether yours does.

Medications and your ears

A small number of medications can affect hearing or cause ringing in the ears as a side effect. If you notice new ear symptoms after starting a medication, do not stop it on your own, but do let your pharmacist or prescriber know. A medication review can be a good time to raise this and go through everything you take.
