Everyone loses their hearing a bit as they get older. However, some people experience much more drastic hearing loss at a younger age – often as a direct result of noise exposure. It’s important to identify when things get too loud so that you can take steps to either protect your ears or turn down the volume. Below is more information on exactly how loud noise damages the ears, how to identify unhealthy noise levels, and how to preserve your hearing:

How does noise exposure cause hearing loss?

Our auditory system is complex and delicate. Hair cells within our ears are responsible for picking up sound waves. When the vibrations are too strong for extended periods, these hair cells and their connected nerve endings can die. Some noises can even be so loud that they instantly rupture our ear drums, leading to instant hearing loss. While sometimes hearing can return, damage can often be permanent.

How loud is too loud?

Our hearing starts to become damaged once sounds reach 85 decibels. As the volume exceeds this, hearing damage occurs more quickly. Below are a few different decibel levels, what they equate to, and how quickly hearing loss occurs:

Safe volume:

• 60 decibels: Normal speaking volume
• 65 decibels: Dishwasher in next room
• 70 decibels: Vacuum cleaner
• 75 decibels: Busy restaurant
• 80 decibels: Alarm clock

Hearing damage occurs within hours of prolonged exposure:

• 85 decibels: Food blender
• 90 decibels: Lawnmower
• 95 decibels: Hand drill

Hearing damage occurs within minutes of prolonged exposure:

• 100 decibels: Factory machinery
• 105 decibels: Helicopter up close
• 110 decibels: Rock concert
• 115 decibels: Chainsaw

Instant hearing loss:

• 120+ decibels: Jet engines, fireworks, gunshots

Signs noise exposure is causing hearing loss:

If you notice ringing in your ears, it’s a sign that hearing damage has already occurred. This ringing can often go away if you make sure to take a break from loud noises the next day, but could become permanent if you keep exposing yourself to loud noise. Muffled hearing is another sign that permanent damage has taken place. If you notice yourself struggling to hear people in conversations, turning up the volume higher on the TV, or not hearing people calling your name, it might be worth seeing an audiologist and getting your hearing checked. Hearing aids can help to restore some hearing, while treatment may also be possible for tinnitus (ringing in the ears).

How to protect your hearing:

Make sure to wear ear protection in loud environments – this could include ear defenders or earplugs. There are specialist earplugs that you can buy for music events that can quieten noise while still providing some clarity. Otherwise, if you can, try to limit time spent in loud environments. When listening to music on headphones, you should also try to avoid listening to music at overly loud levels (many devices will now warn you if the volume is too loud). When buying power tools and appliances, look into quieter options that can help to reduce your exposure to loud noise and wear ear protection when operating.
