You should also have found sound levels drop off quickly as you get farther from the source..
What is the 3dB rule?
3dB rule and maximum exposure to noise To put it in context, a worker exposed to a continuous sound intensity level of 83dB(A) for one hour would be exposed to the same amount as someone exposed to an 80dB(A) level for two hours.
What sound can kill you?
Acoustic grenades can go roughly from 120 decibels to 190 decibels. German researcher Jurgen Altmann showed that a blast of 210 decibels or more affects the inner organs — the lungs — and could cause internal injury that could lead to death. A blast will impact the body, and would do so very violently.
Can a sonic boom kill you?
The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure. … High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage.

Can sound be dangerous?
If the sound is very quiet, it will not cause damage even if you listen to it for a very long time; however, exposure to some common sounds can cause permanent damage. With extended exposure, noises that reach a decibel level of 85 can cause permanent damage to the hair cells in the inner ear, leading to hearing loss.
What is the loudest sound on earth?
The Krakatoa volcanic eruption: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB.
How many Hertz can kill you?
Sounds around 19 hz match the resonant frequency of the human eyeball, with reports of apparitions as detailed by the Coventry Telegraph newspaper. The most dangerous frequency is at the median alpha-rhythm frequencies of the brain: 7 hz. This is also the resonant frequency of the body’s organs.

Why is silence so scary?
People who struggle with silence also often feel the fear to be left alone and fear the unknown. … Part of the reason silence is so scary is that it creates a sense of anticipation — or anxiety — depending on what you’re hoping to expect. Without aural cues to alert you to what’s going on, anything seems possible.

It’s noisy. The brain creates noise to fill the silence, and we hear this as tinnitus. Perhaps only someone with profound deafness can achieve this level of silence, so paradoxically loud.
Can sound be weaponized?
Most sound has been weaponized to disorient or anger opponents. In World War II, during the German siege of the Soviet city of Stalingrad in 1942, Soviet troops kept German forces awake at night by playing Argentine tangos through loudspeakers. In Vietnam, U.S. forces turned sound into psychological warfare.
Can silence kill you?

Can humans hear sonic sound?
Ultrasonic hearing is a recognised auditory effect which allows humans to perceive sounds of a much higher frequency than would ordinarily be audible using the inner ear, usually by stimulation of the base of the cochlea through bone conduction.
Can ultrasonic waves hurt humans?
What is the evidence that ultrasound causes harm? There is very little evidence on the effect of ultrasound on human health, either to show that it does or does not cause harm.
What is the loudest thing in the universe?
As far as I’m aware, the Perseus galaxy cluster is the current record holder for the loudest sound discovered in the Universe. Generating sound requires two conditions. First, there must be a medium that the sound waves can travel through, like air or some other gas.
What sound frequency is harmful to humans?
Low frequency sounds can be harmful Human beings are normally able to detect sounds in the range of 20-20,000 Hz and it is well known that sounds within this range can damage the hearing. However, sounds under the frequency of 20 Hz can also affect the ear even though we are unable to hear them.
Can whales kill you with sound?
Sperm whales are so loud that their clicks are capable of killing a human within their vicinity, says one science and adventure journalist. … “These clicks are so powerful in the water that they can blow out your eardrums easily, and they can actually vibrate a human body to death,” he said.
