![]() While this was solely about toxicology, the basic principle translates to our example here the decibel level (depending) is not always the issue but the time spent exposed to it is. In the words of Swiss physician, Paracelsus: “the dosage makes the poison”. Two of the most important aspects to remember when it comes to this potentially dangerous dB level, include the amount of time spent in these environments, distance, and natural noise suppression. Before you rush off to grab your nearest pair of noise-canceling headphones, there are some other factors to consider as to why this isn’t an inherently bad thing. Examples include heavy traffic, a motorcycle, and even a noisy restaurant. There are a number of everyday sounds that meet, or edge over, the 85dB level which can impact your hearing. ![]() Still, it’s important to understand that there are a wide variety of factors that you should consider as well. You needn’t worry too much – examples of 120dB sound include live indoor music concerts and jet engines. Also, if these hair cells are sufficiently damaged, they can die, which would lead to permanent hearing loss. Unfortunately, hair cells cannot regenerate, regrow, or heal, and so if they are damaged, they can never return to full function, diminishing your hearing ability. These hairs in your cochlea react to the vibrations from incoming sound waves, and are responsible for sending electrical signals to your brain to process the sound. Sounds at these intense levels can also damage the tiny hairs, stereocilia, in your ears. This won’t be immediate, but you will not need to be exposed to these sounds for very long periods for the effects to take hold.Īs this isn’t an exact science, there is no determining how long you can be bombarded with sound at 85dB or higher, so it’s considered best practice to remove yourself as quickly as possible from the noisy area, or put on safety equipment as quickly as possible.įurthermore, any sound at 120dB will have an immediate impact on your hearing, and in some cases, can be severe enough to rupture your eardrum as soon as it hits your ears. ![]() Sounds at, or above, this level can have lasting, permanent effects on your hearing, and will most likely lead to a reduction in your hearing ability. ![]() Theoretically speaking, any noise level that is above 85dB is considered harmful to one’s hearing. There are a number of influencing factors that we need to factor in, such as how long we are exposed to the noise, whether we are using safety equipment and the fact that everyone’s hearing, and sensitivity to sounds, is unique. We hear so many sounds on a daily basis, and all at various volume levels, so it’s only natural to wonder at what point we may be damaging our hearing.Īs with a number of other “harmful” things, it’s not as clear-cut as we would like it to be. At one point or another, you might have wondered “what decibel level is harmful to my ears”. ![]()
