The scaryness of sound: saving people and destroying each other in a narrow way!

When studying sound, scientists were amazed at what it could do: destroy, and heal.

Studies in recent years have shown many unexpected power of sound. Saving people, but can also kill people. Is it a joke?

The more we know about the world around us, the more we see a truth: the power of the simplest things is endless. Nature keeps us going from one surprise to another.

When studying sound, scientists were amazed at what it could do: destroy, and heal.

This makes them ask a question: where is this limit or ability? Can sound save people, or . kill people?

Depending on the frequency and intensity, the sound will have different effects.

Now, within the limits of our knowledge and techniques, sound can heal but not kill people. Depending on the frequency and intensity, the sound will have different effects.

Sounds can heal

The recorded sounds are able to help us recover faster, which is the sound emitted by the Tibetan bell, or the tuning fork . In addition, therapeutic recordings contain special sound frequencies such as 528 Hz or 432 Hz is also receiving medical approval.

The sound of the Tibetan bell, or the tuning fork . helps us recover faster.

Science has shown that these sounds affect brain waves, helping patients improve their morale, relieve pain and stimulate recovery of damaged areas.

The mechanism behind this miraculous phenomenon is still a mystery, but it is clear that medicine has a very effective healing tool.

. and sound can also be destroyed

In contrast to the above, scientists also discovered the ability to destroy matter of sound waves. When a sound has the same frequency as the vibration frequency of an object, the object will start to vibrate. This phenomenon is called resonance .

The sound coincides with the frequency of the cup, causing it to vibrate and eventually break.

This is similar to the parts of the human body, because each organ has its own frequency. For example, the eyeball has a natural frequency of 19Hz. So what happens if a person in the area has sound with the frequency falling right on 19Hz?

Very simply, the person's eyes will vibrate until the sound disappears. If this oscillation is strong enough and lasts long enough, their vision may be severely impaired.

Besides, sound with too great intensity also caused negative impacts equally. Scientists calculate that if this index reaches 240 dB, the sound will officially become a deadly weapon.

The sound may have a negative effect on health - it has not yet been able to kill people.

However, the greatest intensity we can create is only 154dB. That means that until now, sound may have a negative effect on health - it has not yet been able to kill people.

It can be said that humanity's greatest strength is knowledge . Understanding this knowledge, people can make the world grow stronger thanks to its application.

As to how we will use it, for good or bad purposes, only time can be verified.
