We live in a world full of sound — from the hum of traffic to the beat of your favourite playlist. But many of these sounds come at a cost. As a society, we don’t do nearly enough to protect our ears from harmful noise exposure, even though noise-induced hearing loss (NIHL) is 100% preventable. The risk isn’t only for older adults; everyone is at risk — from young adults at concerts to tradespeople using power tools.
Hearing Loss in South Africa: The Latest Stats
According to the World Health Organisation (WHO) and South African Hearing Institute, an estimated 1 in 10 South Africans lives with some degree of hearing loss. This number is rising, with noise exposure being one of the most significant contributors — especially among young adults and workers in industries such as construction, mining, agriculture, and entertainment.
A recent study indicates that over 15% of South Africans aged 20–44 have signs of early hearing loss, much of it due to prolonged exposure to unsafe noise levels. Despite this, many are unaware their hearing is being damaged — until it’s too late.
How Loud is Too Loud?
Noise levels are measured in decibels (dB). Any sound above 85dB can cause damage over time, especially with repeated or long-term exposure.
Here’s a quick guide:
- Whispering – 30 dB
- Conversation – 60 dB
- Busy traffic – 70 to 85 dB
- Motorbike – 90 dB
- Headphones at max volume – 100–110 dB
- Jet engine at takeoff – 120 dB
The louder the noise, the less time it takes to cause damage. Apps that measure noise levels are a great tool — just make sure they’re calibrated for accuracy.
What Happens When You Damage Your Hearing?
Inside your inner ear are delicate hair cells responsible for translating sound into signals your brain can understand. When exposed to loud noises, these cells can become damaged or destroyed — and they do not regenerate. Once gone, they’re gone for good.
That’s why protecting your hearing isn’t something you can postpone — it’s something you must start doing today.
Everyday Ways to Protect Your Hearing
Whether you’re on a worksite, at a festival, or mowing the lawn, you can reduce your risk of hearing loss with affordable hearing protection:
- Foam earplugs
- Pre-moulded earplugs with frames
- Earmuffs
- Custom-moulded earplugs
- Wax or silicone wadding
These simple tools can reduce harmful noise exposure by 15 to 30 dB, often enough to bring dangerous sounds down to safe levels.
Spotting the Warning Signs of Hearing Loss
Many people don’t realise they’re losing their hearing until it’s too late. Watch out for signs like:
- Ringing or buzzing (tinnitus)
- Needing to turn up the TV volume
- Difficulty following conversations in noisy places
- Muffled or distorted sound perception
If you notice any of these symptoms, book a hearing evaluation with Strauss Audiology. We use advanced diagnostics to assess your hearing health and recommend the best course of action.
Take Control of Your Sound Environment
Your home and lifestyle choices can also make a big difference:
- Add soft furnishings (curtains, rugs, cushions) to reduce echo and absorb sound.
- Use hearing protection when using power tools, lawnmowers, or leaf blowers.
- Adjust your car stereo volume based on road noise — louder engines often lead to louder music.
Protect Your Ears When Swimming
If you swim in cold water or open seas, use custom swim plugs to prevent ear infections and surfer’s ear — a common condition where bone grows in the ear canal due to cold water exposure.
Ear Care Tips
- Never insert cotton buds or other objects into your ear canal.
- Ensure hearing loss is noted in your medical records, especially if you’re prescribed medication (some medicines are ototoxic).
- Schedule annual hearing tests at Strauss Audiology to monitor your hearing health.
- Watch for any changes in your hearing or tinnitus symptoms and contact us if you have concerns.
FAQs About Hearing Protection
Q: Can my ears get used to loud noise?
A: No. If loud noises no longer bother you, it might be because your hearing has already been damaged. This is a sign to seek help — not ignore it.
Q: Are earplugs safe to use daily?
A: Yes, especially if you’re in noisy environments regularly. Just ensure they’re clean and properly inserted.
Q: What’s the best hearing protection for concerts or clubs?
A: High-fidelity or musician’s earplugs are ideal — they reduce the volume without distorting the sound.
Q: Can children use hearing protection?
A: Absolutely. In fact, children are more sensitive to loud noise and should use earmuffs or child-sized plugs at events, during fireworks, or around loud machinery.
Q: How often should I have my hearing checked?
A: At least once a year, especially if you are over 40, work in noisy environments, or have noticed changes in your hearing.
Final Thoughts
Your hearing is precious — once it’s gone, it’s gone. By making small changes today, you can protect your hearing for the future. Whether it’s at home, work, or play, use protective gear, stay aware of noise levels, and book regular check-ups.
