Decibels in electronics
WebDecibel is a logarithmic expression used in filter applications as a unit of gain or loss. Characteristic of logarithmic operations, processes involving multiplication or division are … WebNov 6, 2024 · The logarithmic scale that measures sound and loudness is called a decibel. Sound energy travels in waves and is measured in frequency and amplitude. The intensity of the noise emitted from air conditioning units, for example, is the force of the sound wave (amplitude) and is measured in decibels (‘dB’).
