A Refresher on Noise Pollution TodayHere’s the thing about many kinds of hearing loss today – it’s totally avoidable when you’re well-educated and make certain shifts in your lifestyle to ensure that you’re keeping your ears and the rest of you safe and healthy. If you’re a new visitor to the Hearlink blog, welcome! We’re so excited that you’ve stopped by. Our goal here is to not only showcase the work that we do, but to shed light on what else is going on in the industry. If you every have questions about the work that we do, hearing loss and your health in general, this can become your new home. We know that a lack of education is the number one reason why specific types of hearing loss like those caused by noise pollution are still prevalent. So, we try to refresh content on here as frequently as possible to help explain how hearing loss works. Today, we’re focusing on a refresher on noise pollution.


Let’s start with a fun fact. Did you know that you have more than 15,000 tiny hair cells in our ears? These aren’t aesthetic; they actually act as sound detectors. This may sound odd, but when you hear a sound and the sound waves pass into your ears, the hair cells will then send a signal straight to your brain. It’s then the job of your brain to decode the sound, no matter what it is. If you have healthy hair cells, the sound is able to be transmitted and decoded with no issues. However, if there has been any damage to the hair cells, the brain will receive a distorted sound. If they’re really badly damaged, then your ears will not be able to detect any kind of sound. Think of it like a walk in the park. The first time you step on grass, it returns to its upright position. But, if you continue to walk on the same grass, you will cause it to wear over time. The hair cells bend over time, but more so when they’re exposed to noises at very loud volumes.


This isn’t just an issue that takes place over time. One single incident can cause permanent hearing loss, if it’s loud enough. This is why safe noise level ordinances are passed down by organizations all around the world, stemming from information from the World Health Organization. If you add six decibels to any volume, it will double with magnitude of sound. 80 and 86 decibels may sound like a negligent difference, but it will actually double the volume for your ears. Stick to 85 max, that’s a freight train that’s 100 feet away, in order to keep those hair cells safe. That number is up in fact from back in the 1970s when it was closer to 70. We’re making shifts to acclimate to our lifestyles today, but it’s important to keep the health of your ears as a priority.
