Decibel (dB)
Decibel (dB) is a unit of measurement used to express the ratio of two values of a physical quantity, often power or intensity. In the context of space and astronautical engineering, decibel is commonly used to measure the sound pressure level of rocket engines and other spacecraft propulsion systems. It is also used to measure the signal strength of communication systems, such as radio and satellite transmissions. Decibel is a logarithmic unit, which means that a difference of 1 dB represents a tenfold difference in power or intensity. For example, a sound that is 10 dB louder than another sound is actually 10 times more intense. Decibel is a useful tool for engineers and scientists to compare and analyze data, as it allows them to express large ranges of values in a more manageable and meaningful way.
