Difference between Decibel and Sound

Decibel vs. Sound

The decibel (symbol: dB) is a unit of measurement used to express the ratio of one value of a physical property to another on a logarithmic scale. In physics, sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid.

Similarities between Decibel and Sound

Decibel and Sound have 18 things in common (in Unionpedia): A-weighting, Acoustics, American National Standards Institute, Amplitude, Attenuation, Decibel, Hertz, International Electrotechnical Commission, Loudness, Pascal (unit), Phon, Root mean square, Sine wave, Sone, Sound intensity, Sound power, Sound pressure, Underwater acoustics.


A-weighting is the most commonly used of a family of curves defined in the International standard IEC 61672:2003 and various national standards relating to the measurement of sound pressure level.
