How Loud Is 130 Decibels

The continuous noise level of a jet engine is 130 dB and the sound pressure at which it begins to be noticeable for humans is 120 dB.

The difference in noise levels between these two levels is extremely small — just one-tenth of a decibel or 0.1 of a meter. It’s important to note that the volume of a jet engine doesn’t change over its 100,000-hour lifetime. In fact, the sound intensity stays about the same for that long as well.

That means that roughly every 100,000 hours, you could hear an engine passing by your bedroom window if you were sleeping at night. And if you sleep through it (which I don’t recommend), then in a few hours or days you will be able to hear it again (though not as loudly).

You don’t have to worry about being awake when this happens; engines are so powerful they will just continue on past your window until they burn out completely.

130 dB is as loud as, for example, a jet engine take off.

This is a fairly common question. In this topic, I will discuss the impact of 130 dB on your hearing and how loud it is.

You can hear sound clearly at a frequency of about 20 Hz. A sound source at 20 Hz is at a distance of about one meter to you. Around this distance, the human ear will not detect any significant difference in sound level. However, if you are standing closer to the source, these sounds will be perceived as louder if you are exposed to them for longer periods of time (i.e., imagine your ears as having been “turned up”).

If you have had any experience with music or listening to radio or TV, then it’s likely that you have heard sounds which are louder than those normal background noises which are already a prominent part of the environment around you. For example, in the car or in a quiet room, some people may hear background noise such as traffic sounds or other people talking while others may only hear music playing out loud; however no one can hear what is playing out loud unless they are right next to it (if they don’t move away).

130 decibels is approximately equivalent to the sound level emitted by a jet engine taking off from an airport at an elevation of 50 m (164 feet). At this distance from the noise source, there should be no audible difference between the two types of noise because neither type of noise has much energy when compared against each other (at 70 m (230 feet) from the noise source), but as someone gets closer towards it, there should be noticeable differences due to attenuation and electricity currents present between different types of electrical cables and wires in buildings and automobiles .

130 dB is an extremely intense noise level that can instantly damage your hearing.

It is difficult for most people to imagine how loud a sound is. They might assume a sound level of 130 decibels is too loud to register in the ears of an average person, but this is not the case. 130 decibels is as loud as, for example, a jet engine take off. It is an extremely intense noise level that can instantly damage your hearing.
When you hear 130 dB, it is important to note that it’s not actually louder than a jet engine at takeoff (for comparison sake). The noise source used in this experiment was a fan and the aircraft was 50 feet away.

The fan was used because it produces much more sound pressure than several other sources of sound such as cars and airplanes, which are used in many commercial jet engines tests.

Airplane engines do produce high-intensity sounds but they don’t cause hearing damage compared with other types of noise sources such as explosions.

The best way to understand how loud 130 dB really can be is to spend some time with a friend who works on big construction projects. Let them know that they will have to work on a very long shift without any break at all if they want to keep their hearing intact.

After that, let them try listening to an experiment where you turn up the volume on their computer speakers by using headphones rather than speakers because both are equally loud sources of sound (although headphones are quieter than speakers).

It should be quite easy for them to determine just how much louder their computer speakers are than their friends’ headphones (though your friends’ headphones may seem more comfortable).

But if they simply connect their phones or similar devices into their computer speakers, then listen at full blast with no distractions, then in about 20 minutes they will not only be able to hear clearly, but also feel what it’s like when someone pushes on your eardrums with full force!

How do humans survive sound blasts at such high levels?

The intensity of sound at 130 decibels can instantly damage your hearing. It is the sonic equivalent of a jet engine take off. For most people, 130 decibels is enough to cause temporary deafness .

The human ear can only physically tolerate sounds up to 120 dB

In the world of sound, the human ear is not an instrument. It is an organ. As such, it can only hear sounds that are at or below a certain volume.
The human ear works differently from other organs when it comes to listening to sounds. If you ever heard a very loud opera singer your ears would probably be ringing for days.

That’s because the maximum level that can be reached by our ears is about 90 dB (decibels). The blood vessels in our ears dilate and blood rushes into them to help the organs work more efficiently. This increase in blood flow ensures there is more oxygenated blood flowing through the ear canal and around the eardrum, which is why we hear better at higher volumes!

How Loud Is 85 Decibels

The sound of 85 decibels, in the human ear, is equivalent to that of a factory diesel engine cranking up full throttle. The sound of 85 decibels is loud enough to cause immediate damage. At 85 decibels, we would be unable to hear ourselves think for about three seconds.That’s why it’s important to understand how loud your speech is compared with others when you prepare for a speech.

If you are confident that your speech will be loud enough to be heard and understood by the audience you must know how loud it will be; otherwise, you could come off as arrogant.A study titled “How Loud Is 85 Decibels?” conducted by researchers from the University of Minnesota tested groups of college students on their ability to identify different loud noises and distinguish them from other noises.

The test was conducted in a controlled environment where there were no distractions and participants were given no prior knowledge about the nature of the test — they simply had to hear what they heard, as they had never heard anything like it before.The results showed that our hearing perception is much more sensitive than we may think; it isn’t just an average person who can hear above 85 decibels but anyone can do so based on their own personal characteristics, such as their hearing sensitivity or age. This also goes for people who have trouble hearing voices too. A study titled “The Effects of Age and Hearing Loss on Hearing at 85 dBs: An Experimental Study” conducted by researchers from the London School of Economics found that even a few years after being diagnosed with hearing loss, people with normal hearing could still identify pressure sounds at levels well over 90 dBs (85 decibels).

In fact, this study found that even though most people may not have normal hearing in some cases and may experience some hearing loss or noise-induced hearing loss (NIHL), most people still can identify pressure sounds above 85 dBs (85 decibels) which should give everyone pause before speaking loudly during meetings or public events .

Why is Sound So Loud?

As humans, we’re pretty good at picking up sounds of objects. For example, when you hear a car coming from across the street, you can usually identify their sound.The louder an object is, the more distinct it becomes — “That’s a car. That’s a car. There’s a car coming! A loud one! A car! A big one! A big burly one! A big scary one!”That’s what is happening when you are hearing 85 decibels or more.Now, as I said before, decibels are measured in terms of sound pressure levels (SPL). For example, if you were holding your ear close to something like a speaker and hearing 85 decibels or more and thought that it was loud enough to be considered “loud enough to be considered deafening” (i.e., the equivalent of being deafened), then you would probably pass out from shock and pain.But let me tell you about the real world consequences for being exposed to 85 decibels or more.

The Effects of Noise on the Body

One of the stories we covered recently was about how loud a football play was. People were visibly shocked by the sound of the soundclash and had to be restrained from running away from the stadium. Soundwaves can travel at speeds up to 120 miles an hour, or 60 mph, so that sounds can travel for hours and even days before being detected by human ears.This topic is extremely relevant among the noise-sensitive population, who are constantly bombarded with loud noises from numerous sources including airplanes, construction sites and public transportation systems.Noise-sensitive people are more likely to suffer from hearing loss as a result of exposure to noise levels above 85 decibels (85 db), and have been described as having “slow brain cells” due to their sensitivity level.  

However, there is also evidence that noise is bad for your health , according to this review paper  on noise and health .

The authors evaluated scientific evidence on various aspects of noise exposure:

  • effects on work productivity;
  • impacts on sleep quality;
  • effects on cognitive function;
  • impacts on hearing;

and effects on health-related outcomes such as cancer incidence. 

They concluded that “the evidence shows a causal relationship between some types of noise and increased risk for adverse health outcomes.”The impact of sound on human cognitive functioning has been an area of interest in recent years, especially in relation to sleep deprivation disorders such as sleep apnea or narcolepsy .

One recent study showed that listening to music at 16 dB resulted in less cognitive performance than listening at 20 dB , while another study showed no difference between similar music levels between groups with vs without sleep deprivation disorders. This topic is especially important when you’re trying to get your audience’s attention but they seem like they’re not paying attention because they’re all busy staring at their tablets or phones.

How to Protect Your Hearing From Loud Sounds

Your ears are the most sensitive organs in the human body. They register sound waves and allow you to hear a wide variety of sounds ranging from a whisper to a roar.

The ear is made up of two kinds of tissue:

One hears sound waves that travel through the ear canal, or external auditory canal, which is where our ears are located.

Our inner ear consists of three parts:

The semicircular canals, which are also called cochlea;

The tympanic membrane, which is where sound travels into the inner ear;

And cells that contain hair cells that convert sound into electrical signals, called nerve cells.Sound travels through the air and bounces off objects inside your ears such as hard surfaces or vibrating objects like a fan belt or computer keyboard. It is then picked up by your eardrum and transferred to your inner ear using tiny hairs on the outer surface of your eardrum. The inner ear contains two kinds of specialized cells called cochlear nerve cells that convert sound into electrical impulses (sound nerves).

A good-quality set of hearing aids can help amplify certain frequencies, but they aren’t necessary for normal hearing—which means you will still be able to hear sounds at 85 decibels without them.If you want to protect your hearing from loud noises like gunshots or trains passing by on tracks near you, it’s a good idea to wear hearing protection like earplugs or mufflers when you go outside for long periods of time at night or during storms.

If there is any chance that loud noise could come from an unexpected source such as a lightning strike or construction equipment nearby, see if there are any audible warnings posted at construction sites. It’s also a good idea to take precautions if there is any chance you might have to enter an area where loud noises like thunderstorms might occur in order to make sure no one catches you unprepared; if so, wear hearing protection too!


In the last installment, we discussed the meaning of loud. We also looked at some of the factors that can contribute to noise levels and how they differ between different environments.In this installment, we will discuss the effects of loudness on human hearing. Here, we will look at three levels: mild, moderate, and severe. All three are intended for public listening rooms where people are often exposed to noise levels that can be considered “loud” in nature.

The next level is called “severe” because it is associated with more intense sounds, such as a jet airplane taking off or a military helicopter flying overhead.The third level is called “moderate” because it is not constantly exposed to loud sounds; rather it is only used in situations where there are many other people around who may be engaged in conversation and may hear your speech loud enough for you to be aware of their presence.If you want to know how loud 85 decibels sounds like, put your ear against a windowpane on your way home from work every day once or twice during the week and listen closely at work on Monday through Friday throughout the workweek.

How Loud Is 120 Decibels

120dB is the amount of sound pressure a human ear would hear at one meter (about four feet) from a source that emits no more than 120dB. It’s also known as the threshold of hearing or absolute hearing threshold, and it is equal to the pressure wave at which we perceive a sound as being heard by our ears.

It’s interesting to note that there are two types of sound waves: acoustic waves and mechanical waves. Acoustic waves are generated by vibrating materials like air or water. Mechanical waves, on the other hand, are created by forces like gravity and friction.

Acoustically-generated sounds such as sirens, applause, thunder and fireworks can be very loud; they can even exceed 120dB in some cases! But when you want to create sounds with mechanical action like earthquakes or aircraft engines, you will need to use an instrument called an ear trumpet which produces both mechanical and acoustic signals at the same time.


120 decibels is the equivalent of how loud a sound wave is when it’s at its peak — the point where it’s most intense. It’s the equivalent of 100,000 volts (which is what can happen during an electric shock).

It’s been said that 120 dB can kill a person. It was also once thought that 120 dB was impossible to hear without losing hearing altogether. The new scientific consensus has determined that it’s possible to hear and feel a 120 dB sound wave without any loss of hearing.

Our ears aren’t just sensitive to sound waves; they are also sensitive to vibrations. Vibrations are produced when you shake your hands or feet while swaying or moving your head up and down. When you walk, you create movement in all directions — left, right, up, down, forward and backward.

And while running, this movement has been found to produce vibrations that are more intense than sounds produced by cars driving on a motorway at 100 mph (110 km/h).

What this means for us as writers is that if we want our readers to feel their words over their shoulders and not be distracted by their surroundings or run into something in their path — we need to use words with higher pitch than normal when writing.

Normal Conversational Levels

There’s a lot of information to be had about what is considered “noise” and how loud things can get.

The average noise level for most people is around 40 decibels, or 40dB.

Noise has a serious impact on our lives; it can cause safety concerns, health issues, and even interfere with our sleep patterns.But what exactly is noise? Most people think that noise is the sound of something like a motor or loud machinery.

But while those are definitely examples of noise, they are not typically considered “noise.”

What you may have noticed when walking down the street or reading in bed at night is not just sounds from your surroundings, but also noises from other people’s conversations. Loud music also falls into this category of “noise.”

People hear and feel sounds that are louder than 40 dB quite often without us even knowing that there was any sound at all!

Below we will explore how loud 120 dB actually sounds and why it isn’t so common knowledge (as you might imagine).We want to make sure that the information you get from this article is as complete as possible and will help you to avoid common mistakes when trying to understand what noise means in the first place!

Loudness Perception

120 decibels is about as loud as you can be without a sledge hammer. This isn’t a measurement of sound pressure. It’s a measurement of how loud something feels.

Sound pressure and sound intensity have completely different meanings when it comes to measuring the volume of sound waves. A sound pressure level is simply how loud the sound wave is and it doesn’t take into account its frequency or intensity and therefore, it will never measure 120 dB.

Furthermore, a sound pressure level can vary by a great margin depending on the nature of the object being measured. For example, if you are standing near an electrical outlet with your ear partially covered, then your ear will be further away from the source compared to if you were wearing earplugs so that your ear has to deal with more intense sounds.

However, if you are standing in front of someone’s face with an earpiece inserted in his or her ears then all sounds will be much louder than they normally would otherwise—a factor that affects how loud 120 dB appears on paper as well.

Sound Intensity and Human Perception

Sound intensity is measured in decibels, with a decibel (dB) being one tenth of a bel. The decibel scale can be used to describe the loudness of sounds, which are divided into categories based on their perceived loudness, from barely audible to extremely loud.

The human ear can discern sounds down to about 110 dB in certain circumstances — for example, if an explosion occurs nearby — but even then, the human ear can only distinguish between two frequencies at a time.The perception of sound intensity is based on perceived loudness and not absolute volume.

That’s because there’s another factor involved beyond volume; sound pressure is calculated based on the intensity of the pressure waves. So while 100 dB might indicate a simple explosion that you can hear clearly right next door, 120 dB means that the blast has reached your bedroom and made your walls rattle.

120 dB in a Nutshell

Noise is one of the most interesting aspects of our modern world.So, how loud is 120dB?

The standard definition for measurement is that a sound pressure level that can be heard by humans at a distance of about 20 meters (66 feet) without the aid of amplification devices.One source states that the human hearing threshold for 100dB SPL is about 6-8 decibels, or about one half octave below the audible range for most people.

It’s important to note that this threshold does not apply to speech, which has been measured to have a maximum sound pressure level of 123 dB. But it does apply to pure tones, which we know from previous studies have an SPL of 116 dB, with intermediate amplifiers being able to produce 107 dB or more.The noise we encounter in everyday life can vary in volume, with higher volumes than those noted above being considered “loud” and lower ones being considered “quiet”. As a result, the potential range above 70dB has typically been defined as “moderate noise” and above 105dB as “high noise”.
