At the same time, it propagates farther and attenuates smaller!

The frequency is the resonance requirement of the human body's organs, and the size of the sound is described by decibels that are directly related to the amplitude. The energy doubles every 10 decibels.

It can reach a maximum of 194 decibels under standard atmospheric pressure, because the amplitude reaches the limit and a vacuum has been formed in the low-pressure part. If it is higher, it will be a pure shock wave.

The most 'frugal' lethality produced by the Bone Dragon is the extreme dragon roar that is mixed with multiple frequencies and adjusted according to different atmospheric pressures.

As the Bone Dragon opened its mouth against the dust, a terrifying sound wave appeared, and the next moment the two observing figures in protective suits instantly turned into mud inside the protective suits!

Except for being blown away by the huge airflow and sticking to the wall, the protective suit did not suffer much damage.

The terrifying sound waves were guided by the entrance of the cave and blasted towards the inside without stopping at all...

…

"What sound? Ugh~"

Some of the audible sound frequencies caused the group of experimenters closest to the cave entrance who were playing with the instruments to suddenly vomit when they heard the sound.

Paji~

Eyeballs explode and die quickly!

Infrasound waves propagate extremely far due to their low frequency. Coupled with the magical locking energy, even though many places have excellent sound insulation effects and sound-absorbing materials in many places, the entire experimental base still suffered a violent impact!

Those who were relatively closer were actually fine and died instantly, but many of the guys inside who were unable to reach the fatal level immediately due to various obstacles were reduced, fell to the ground and started wailing.

Various screams, various struggles, and miserable voices asking for help kept appearing, and then continued to gradually decrease under the subsequent dragon roar until they disappeared.

For a moment, the entire laboratory fell into deathly silence, with only the sound of the machines still running...
