When you were a teenager and turned the radio up to full volume, you weren’t thinking about how this could damage your health. You just enjoyed the music.
You had fun when you were growing up, going to the movies and loud concerts. You might have even chosen a job where loud noise is normal. Still, you didn’t think it had any lasting impact.
Now that you’re older and more mature, you probably know better. Noise-induced hearing loss can show up in kids as young as 12. But sound is so powerful it can even be used as a weapon.
Can Sound Make You Ill?
In short, yes. It’s apparent to scientists and doctors alike that specific sound can make you ill. This is why.
How Health is Affected by Loud Noise
The inner ear can be injured by really loud sounds. After sound passes through the membrane of the eardrum it’s picked up by little hairs in the ears. These hairs never grow back once they are damaged. Many people, as they age, deal with sensorineural hearing loss caused by this.
Dangerous volume starts at 85 decibels over an 8 hour time period. It only takes 15 minutes for permanent damage to set in at 100 dB. At 120 dB, the volume of a rock concert, instant, irreversible damage will happen.
Noises can also impact cardiovascular health. Obesity, high blood pressure, clogged arteries, and other vascular concerns can be the result of elevated stress hormones brought on by excessively loud noise. So when people who are exposed to loud noise complain about memory loss and headaches, this may explain why. Cardiovascular health is directly related to these symptoms.
Actually, one study confirmed that sound volumes that start to affect the heart, and hormones are as low a 45 decibels. That’s roughly the volume of a person with a quiet inside voice.
Your Health is Affected by Certain Sound Frequencies – This is How
Cuban diplomats became sick after being subjected to certain sounds several years ago. This sound wasn’t at a really loud volume. It could even be drowned out by a television. How might it have been able to make people ill?
Frequency is the answer.
Even at lower volumes, appreciable harm can be done by certain high-frequency sound.
Have you ever cringed when somebody scraped their nails on a chalkboard? Have you been driven crazy by someone repeatedly dragging their finger across a folded piece of paper? Have you ever had to cover your ears during a violin recital?
Damage was happening to your hearing if you’ve ever felt pain from high-frequency sound. If you endured this for an extended period of time, frequently subjected yourself to it, or were exposed at a high volume, then the damage could have become irreversible.
Research has also found that you don’t even need to be able to hear the sound. Harmful frequencies can come from lots of common devices like sensors, trains, machinery, etc.
Your health can also be impacted by infrasound which is really low frequency sound. It can resonate the body in such a way that you feel nauseous and dizzy. Some even experience flashes of color and light that are common in migraine sufferers.
Protecting Your Hearing
Recognize how particular sounds make you feel. Minimize your exposure if specific sounds make you feel pain or other symptoms. If you’re feeling pain in your ears, you’re probably doing damage.
