Summary of the Article
1. Who can hear infrasound?
Some animals, such as elephants, rhinoceros, and hippopotamus, are known to hear infrasonic sounds. They communicate by producing infrasonic sounds.
2. Can everyone hear infrasound?
Despite the general understanding that infrasound is inaudible, humans with a normal hearing organ can perceive sound below 20 Hz. The perceived character of the sound changes gradually with frequency.
3. Why can’t people hear infrasound?
It is widely believed that human hearing is insensitive to infrasound, which is defined as frequencies below 20 Hz. However, there is evidence that infrasound can alter the processing of sound in the cochlea.
4. Are some people more sensitive to infrasound?
It is possible that some individuals are more sensitive to infrasound and might experience symptoms associated with its presence.
5. Can you protect yourself from infrasound?
Special sound-absorbing ear defenders can protect one’s hearing from infrasound. If these are not available, getting as far away from the source of the sound as possible is the best protection.
6. Can microphones pick up infrasound?
Normal measurement microphones have a wide frequency range and can cover most practical applications. However, special microphones may be required for certain situations, such as measuring infrasound.
7. What happens if you listen to infrasound?
Infrasound waves, which are inaudible to us, can disturb our balance nerve and cause symptoms such as nausea, restlessness, headaches, and tinnitus. Exposure to infrasound can also lead to tiredness and disrupted sleep.
8. What does infrasound do to humans?
Exposure to infrasound can result in changes in blood pressure, respiratory rate, and balance in humans. These effects are typically observed at levels above 110 dB. Levels above 140 dB can potentially cause physical damage to the ear or loss of hearing in humans and animals.

Can microphones pick up infrasound
Normal measurement microphones have a very wide frequency range and cover most practical applications. There are however special situations where special microphones are required. One such application is the measurement of infra-sound.
What happens if you listen to infrasound
Infrasonics affect our body. Sound waves, which we cannot hear, can disturb our balance nerve and cause nausea, restlessness, headaches and tinnitus. A known effect is what we call sea sickness. As well as that, infrasonics can also cause tiredness and disrupted sleep.
What does infrasound do to humans
Among the more consistent findings in humans were changes in blood pressure, respiratory rate, and balance. These effects occurred after exposures to infrasound at levels generally above 110 dB. Physical damage to the ear or some loss of hearing has been found in humans and/or animals at levels above 140 dB.
What is the most annoying sound frequency to humans
The study also shows that sounds in the higher-frequency range of around 2,000 to 5,000 Hz were rated as most unpleasant. "This is the frequency range where our ears are most sensitive,” says Kumar.
Does infrasound go through walls
Infrasound propagates hundreds of miles and can penetrate walls, mountains and other obstacles without loss. The NASA infrasound sensor filters out wind noise that can interfere with detection, while using less power and much less space than currently available solutions.
What disease is caused by infrasound
Vibroacoustic disease (VAD) is a whole-body pathology that develops in individuals excessively exposed to ILFN. VAD has been diagnosed within several professional groups employed within the aeronautical industry, and in other heavy industries.
What devices detect infrasound
When a volcano erupts it'll produce these low-frequency sound waves. But you also have explosions. Like ocean waves the Aurora produces infrasound actually it does yeah it's kind of a unique.
Can you communicate with infrasound
Rhinos, hippos, elephants, whales, octopuses, pigeons, squid, cuttlefish, cod, Guinea fowl, etc. communicate via infrasonic sounds.
What are 3 uses of infrasound
People use this frequency range for monitoring earthquakes and volcanoes, charting rock and petroleum formations below the earth, and also in ballistocardiography and seismocardiography to study the mechanics of the heart.
What frequencies do humans not like
According to a study published in the Journal of Neuroscience, frequency sounds in the range of around 2,000 to 5,000 hertz (Hz) are unpleasant to humans. This frequency range also happens to be where our ears are most sensitive. Healthy humans can hear sound frequencies that range from 20 to 20,000 Hz.
