Decibel with the abbreviation dB is equal to one-tenth of a bel, after Alexander Graham Bell. It is a measuring system first used in telephony in 1929. It is a logarithmic unit of measurement that expresses the magnitude of a physical quantity, usually power or intensity, relative to a specified or implied reference level. Since it expresses a ratio of two quantities with the same unit, it is a dimensionless unit.
Decibel is a logarithmic scale used to measure the ratio between two signals - often used for electrical signals, or sound levels. If applied to a single signal, th second signal is assumed to be some reference point.

What is the average decibel level of thunder during a thunderstorm?
The average decibel level of thunder during a thunderstorm is around 120 decibels.
The scale used to define sound intensities?
Sound intensities are typically defined using a logarithmic unit called the decibel (dB) scale. This scale is useful for measuring the intensity of sound waves, where a small change in decibels corresponds to a large change in actual intensity. The decibel scale is commonly used in fields such as acoustics, sound engineering, and environmental noise assessment.
How The scale used to define sound intensities is called the scale?
The scale used to define sound intensities is called the decibel scale. It measures the relative intensity of sounds based on the logarithm of the ratio of the sound pressure level to a reference level.
True Or False Decibel is a measurement of the amount of pollution?
False. Decibel is a unit of measurement used to express the intensity of sound, not pollution. It measures the level of sound pressure. Pollution is typically measured in terms of air quality indices, concentration of pollutants, or other specific measurements depending on the type of pollution being measured.
What is the scale used to define sound intensities?
Sound intensities are typically measured in decibels (dB), which is a logarithmic unit used to quantify the intensity of sound. The decibel scale compares the intensity of a sound to a reference level, usually the threshold of human hearing.
What is the Welsh for 'decibel'?
The Welsh word for 'decibel' is desibel.
Where does the word decibel originate from?
The word "decibel" originates from the combination of "deci-" (meaning one-tenth) and "Bel," which is named after Alexander Graham Bell. It is used to measure the intensity of sound.
What does the term decibel mean?
The decibel is a unit used to measure the intensity, or power, of a sound. It is a logarithmic unit that compares the power of a sound to a reference level. The decibel scale is commonly used to quantify sound levels and express changes in sound intensity.
