... increase for every factor 10 increase in the voltage or pressure ratio, or approximately 6 dB increase for every factor 2. Note that in physics, decibels refer to power ratios only; it is incorrect to use them if the electrical or acoustic impedances are not the same at the two points where the volt ...

High voltage
The term high voltage usually means electrical energy at voltages high enough to inflict harm on living organisms. Equipment and conductors that carry high voltage warrant particular safety requirements and procedures. In certain industries, high voltage means voltage above a particular threshold (see below). High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to demonstrate arcing, for ignition, in photomultiplier tubes, and in high power amplifier vacuum tubes and other industrial and scientific applications.
