Why is 194 dB the loudest sound possible?

But there’s a limit to how loud a sound can get.

At some point, the fluctuations in air pressure are so large that the low pressure regions hit zero pressure — a vacuum — and you can’t get any lower than that.

This limit happens to be about 194 decibels for a sound in Earth’s atmosphere..

So 0 dB does not mean no sound, it means a sound level where the sound pressure is equal to that of the reference level. This is a small pressure, but not zero. It is also possible to have negative sound levels: – 20 dB would mean a sound with pressure 10 times smaller than the reference pressure, i.e. 2 μPa.

Can sound kill bacteria?

Newsletter. High-frequency sound can kill microscopic pathogens, but the sound waves normally need to travel through a contact medium such as water or gel, limiting the use of ultrasound as a germicide.
