Low Frequency Noise

When infrasound becomes a weapon that can hurt people, the generator hidden in the corner of the building becomes the most secret killer. It is silent, but it can plunge people into endless anxiety and pain. An organized but disorderly release has caused the crisis to sweep across the country. Acoustic expert Li Mo relied on his professional ability to crack the propagation code of infrasound waves and develop a sound locator, which seemingly quelled this silent disaster. However, a piece of information in the forum about "co-frequency resonators" broke the brief calm - this kind of equipment that can capture the natural frequencies of high-rise buildings and aggravate building damage is being spread secretly. On one side is the tranquility and freedom of a wooden house in the mountains, and on the other side is the crisis of destruction of the city's skyscrapers. Li Mo's choice will determine the fate of countless people.
