The 10 Best Earplugs For Concerts
How Exactly Does Loud Sound Damage The Ears?
When too many of these connections are severed, it becomes difficult to distinguish foreground and background sounds.
To understand how loud sound damages the ears, we must first understand what sound actually is. To put it simply, sound is vibration. All noise we hear is caused by vibrations that spread as an audible wave of pressure though some medium, such as air or water. As the sound wave enters our eardrum, it passes into the cochlea. Inside of the cochlea are rows and rows of microscopic hair cells. The sound waves, which as we just learned are simply vibrations, cause these microscopic hair cells to move, sending signals to the brain via the auditory nerve. The various tones are interpreted by the brain based on how quickly they move the hair cells.
The louder the sound, the more the hair cells move. Overworking these hair cells by regularly exposing them to loud sounds can eventually cause them to die. Unlike many other cells in our body, inner ear hair cells cannot regenerate. If enough of your microscopic hair cells die, it will cause permanent hearing loss. Luckily, people are born with more inner ear hair cells than we need to hear what is happening around us, roughly 16,000 on average. We can damage between 30 and 50 percent of them before any loss of hearing is noticeable.
If you have ever attended a sporting event or concert and noticed that sounds seemed muffled after you left or that you heard a constant ringing, you have caused some damage to the hair cells within your ear. When they are damaged, they bend or lie down, very much like blades of grass. If the damage wasn't enough to kill them, they will slowly stand back up over a couple of hours or days, returning your hearing to normal. However, if the damage is too severe, they will die instead of straightening back up. Repeat this process too many times and you'll wind up with hearing loss or tinnitus.
Modern research has also revealed that overly loud noises can also severe connections between nerve fibers at the end of the microscopic hair cells and the brain. When too many of these connections are severed, it becomes difficult to distinguish foreground and background sounds. This is why people with certain forms of hearing damage may have trouble holding a conversation in crowded areas, but be able to easily hear somebody when conversing in a quiet place.
Why It Is Important To Protect Your Ears At A Concert
Most people falsely believe it takes years of exposure to loud noises to cause hearing problems, but this is decidedly untrue. In fact, for some unlucky few, all it takes is one overly loud concert to set in motion a lifetime of hearing and ear problems. It also rarely happens like it does in movies where there is a single, catastrophically-loud clap or bang, like a gunshot, right next to someone's ear. Rather, most people don't even notice it until the fun and music is over and they are leaving the concert. At this point, they may notice a mild ringing or feel like they are in a bubble, much like how things sound when you have a cold and your head is stuffy. For most, these issues will resolve themselves after a couple of hours or days, for others though, this is just the beginning of their problem, as more symptoms may begin to appear over the coming days, months, or even years.
The music at concerts often measures between 100 and 120 decibels.
Sounds don't have to be as loud as many people think to cause hearing damage, either. Repeated exposure to sound levels as low as 85 decibels can cause hearing issues over time, which is roughly equivalent to the noise level of heavy city traffic or a garbage disposal. A normal conversation in a restaurant usually measures right around the 60-decibel range. The music at concerts often measures between 100 and 120 decibels. According to the the Centers for Disease Control and Prevention, 100 decibels has the potential to cause hearing loss after just 15 minutes of exposure, and 120 decibels is enough to instantaneously cause pain and hearing loss.
Considering that the average concert is at least two hours long, there is a high possibility of causing at least some hearing damage. If you're attending an all-day music festival, the odds of causing significant hearing loss are even higher. Don't worry though, we aren't killjoys and definitely aren't recommending that you can't go see your favorite bands in action. Instead, just be smart about it and protect your ears with a pair of concert earplugs so you can avoid being one of the 81 million Americans who suffer from noise-induced hearing loss.
How Concert Earplugs Are Different From Standard Earplugs
Unlike traditional earplugs, concert earplugs won't completely muffle or distort sound. Rather, they are specially designed to preserve sound quality, while at the same time lowering the volume to a more ear-friendly level. They achieve this by using unique acoustic filters that lower noises in a uniform level across the entire sound spectrum. Traditional earplugs lower some sounds more than others, resulting in deteriorated listening experience. Concert earplugs preserve that high fidelity experience you go to a concert to enjoy, while ensuring you don't permanently damage your hearing, so you can continue to appreciate music for the rest of your life.
Another drawback of traditional earplugs is the way they muffle voices. Most people find it difficult to carry on a conversation while wearing earplugs for the same reason that they make music listening less enjoyable — the way they distort some sound frequencies more than others. This can make words and intonation very difficult to comprehend. With concert earplugs, this won't happen. All of the words your conversation partner is speaking will be just as easy to understand, you will just hear them at slightly lower levels. Additionally, concert earplugs generally have a low-profile design so as not to be noticeable by others.
If you still think wearing earplugs to a concert is weird, consider this: nearly every single musician wears them when they perform.
