What is decibel (dB)
Decibel is a dimensionless unit that is written in the subconscious of people mainly as a unit of volume, but the reality is somewhat different. Although it is used in acoustics, it is mainly a general measure of two values. Therefore, it is a unit used in many industries, for example in electrical engineering. Decibel is mainly used for better computation. For too large numbers, the ratios of two numbers may lead to unclear results. The unit got its name after the famous inventor Alexander Graham Bell.
