Sounds are all around us, and sometimes these sounds are so loud that they can damage our hearing and cause what is known as noise-induced hearing loss.
While many loud noises are unavoidable, the increase in the use of personal listening devices, such as headphones and earbuds, in recent years is putting us at higher risk – and where adults were once at greater risk of developing noise-induced hearing loss, the risk for kids is now on the rise thanks to their headphone habits.
Of course, high-volume sounds aren’t always avoidable, despite our best intentions, but there are plenty of things we can do to protect our hearing. The key to healthy hearing is understanding how much damage these loud sounds can cause. It’s not always possible to stop noise-induced hearing loss, but there are many simple everyday strategies you can implement to help with the prevention of noise-induced hearing loss in the future.
Noise-induced hearing loss, commonly abbreviated to NIHL, happens when the structures of the inner ear, including the nerve hair cells in the cochlea, are damaged by noise that is beyond safe levels. All sound is created by vibrations, but when those sounds reach a hazardous volume, the vibrations become more powerful. They can be so strong that they damage the fragile hair cells in the ear, leading to a loss of hearing. Noise-induced hearing loss may be gradual, permanent or temporary.
Many of the sounds we hear in everyday life can contribute to noise-induced hearing loss, from the sound of a lawnmower to New Year’s Eve fireworks – even the buzz of people talking over loud music in a restaurant. They’re all sounds we associate with daily life but can adversely affect our hearing as the cumulative effects of sound exposure take hold.
There are two main types of NIHL:
Sound is measured in decibels (dB), and the volume matters as much as the duration. Regular exposure to sounds at 85 decibels or above can affect your hearing permanently, so it’s important to take steps to combat this.
How loud are everyday sounds?
Sounds above 85 dB can increase the risk of hearing damage with regular or prolonged exposure.

Noise-induced hearing loss can happen suddenly or gradually over our lifetime. A single incidence of very loud noise, such as a gunshot or firecracker going off very close to the ear, has the power to create sudden noise-induced hearing loss. However, for most people, the damage is more gradual. Sometimes, exposure to a sudden or continuous loud noise can cause temporary hearing loss. But while hearing appears to return anywhere from 16 to 48 hours later, research suggests that long-term permanent damage to your hearing occurs. NIHL can also cause high-pitched tinnitus.
Some signs of NIHL include:
If you notice ringing in your ears or ongoing trouble hearing after loud noise exposure, it's worth booking a hearing check rather than waiting for it to resolve on its own.
The important thing to remember is that you can take preventative measures to protect your hearing. Some ways you can protect your hearing and prevent hearing loss include:

Unfortunately, noise-induced hearing loss is permanent. Once damage has occurred to the delicate sensory nerve hairs in the cochlea, there is no way to reverse it. However, there are treatment options that can help sufferers hear again, and the one that is right for you will depend on the severity of the hearing loss. Common treatments include:
Left unmanaged, NIHL can also affect quality of life beyond hearing itself, including increased stress, fatigue and a tendency to withdraw from social situations because conversation becomes harder to follow.
