![]() This is because the decibel scale is logarithmic, not linear, and describes progressing measurement changes. Imae By Canva Design 120 dB Comparison To Other Sound LevelsĮach time a sound’s level increases by 10 dB, its intensity also increases 10 times. In the decibel chart below, you can see a graphic representation of safe and harmful decibel levels (yellow sound levels are ok, red sound levels are harmful). ![]() The recommended exposure time decreases as noise levels exceed 85 decibels, which is the limit from which sounds are considered harmful to the human ear. For babies, the maximum decibel level they should be exposed to is 50-60 dB. Here are some examples of maximum recommended exposure times:Įxposure to sounds below 70 decibels is considered safe for human hearing no matter how long you are exposed to this level. It is important to note that 120 decibels is a noise level so extreme that it can instantly damage your hearing and being exposed to such loud noises for even a few seconds can cause irreversible hearing damage or hearing loss.įor the human ear, which is very sensitive especially to sound impulses, exposure to noise levels above 85 decibels becomes dangerous after 8 hours and the recommended maximum exposure drops each time there is the slightest increase in decibel level. the sound made by some animals like the North American bullfrog or Northern elephant seals.a loud alarm or siren such as an ambulance siren.To better understand how loud that is, here are more examples of what 120 dB of sound is equivalent to: In fact, on a decibel chart, 120 dB marks the limit from which sounds become painful and very dangerous to the human ear. How Loud Is 120 Decibels?ġ20 dB is a decibel level that describes extremely loud sounds. This scale runs from 0 dB, which is equivalent to the quietest sound a human can perceive and goes up to 140 dB, a sound level that can instantly cause hearing loss.ġ20 decibels sounds like or is equivalent to the noise generated by:Īs you can see, 120 dB is a very loud noise level, close to the upper limit of the decibel scale. When we want to find out just how loud a sound is, we turn to the decibel scale to learn the answer. In this article, we’re taking a closer look at this decibel level to see what it is equivalent to and how intense a 120 dB sound can get. If you are curious as to just how loud 120 decibels is, you’ve come to the right place. Measure Decibel Levels with DecibelPro App.How to Protect Your Hearing at 120 dB Sound?.120 dB Comparison To Other Sound Levels.If you have a sones rating and would prefer a decibel rating, a chart like the one below can be a good tool for understanding the loudness of the equipment you are interested in. Most industrial products, if given a sound rating, will have a decibel rating versus a sones rating. For example, a sound that is 10 times more powerful than 0 dB (near silence) is 10 dB, while a sound that is 100 times more powerful would be 20 dB. Instead of using a linear relationship like sones ratings do, decibels use a logarithmic formula that is a very useful tool for measuring sound. Decibels are used to measure the pressure of sound. They are also usually measured in half-sone increments.ĭecibel ratings are a more complicated formula. The sones formula is linear, so 1 sone is precisely half as loud as 2 sones and so on. We hear sound differently based on the frequency, so the higher the frequency, the better we can hear that sound. Sone ratings were created to measure how loud we perceive something to be. While sones and decibels both can be used to measure sound, they focus on different aspects of loudness.
