Sound waves can incapacitate or kill.
1400 years ago nobody believed that sound can injure or kill anyone. But today we know this is false.
Sonic and ultrasonic weapons (USW) are weapons of various types that use sound to injure, incapacitate, or kill an opponent. Some sonic weapons are currently in limited use or in research and development by military and police forces. Some of these weapons have been described as sonic bullets, sonic grenades, sonic mines, or sonic cannons. Some make a focused beam of sound or ultrasound; some make an area field of sound.

Sound waves can injure, incapacitate or even kill. This was known recently, however this was portrayed in the Quran 1400 years before it was discovered. In the story of Thamud the people were killed by a sound wave.
[Quran 11:67] And the shout struck those who transgressed, and they became motionless bodies in their homes.
"Saiha صَّيْحَةُ " means shout or scream. Here the people were hit by a sound wave. The angles, who execute God's orders, shouted at Thamud, killing them by a sound wave.
How could an illiterate man who lived 1400 years ago have known that extreme sound can kill?
