# Decibel and Sound

## 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

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.

### Acoustics

Acoustics is the branch of physics that deals with the study of all mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound.

### American National Standards Institute

The American National Standards Institute (ANSI) is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States.

### Amplitude

The amplitude of a periodic variable is a measure of its change over a single period (such as time or spatial period).

### Attenuation

In physics, attenuation or, in some contexts, extinction is the gradual loss of flux intensity through a medium.

### Decibel

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.

### Hertz

The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units (SI) and is defined as one cycle per second.

### International Electrotechnical Commission

The International Electrotechnical Commission (IEC; in French: Commission électrotechnique internationale) is an international standards organization that prepares and publishes International Standards for all electrical, electronic and related technologies – collectively known as "electrotechnology".

### Loudness

In acoustics, loudness is the subjective perception of sound pressure.

### Pascal (unit)

The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength.

### Phon

The phon is a unit of loudness level for pure tones.

### Root mean square

In statistics and its applications, the root mean square (abbreviated RMS or rms) is defined as the square root of the mean square (the arithmetic mean of the squares of a set of numbers).

### Sine wave

A sine wave or sinusoid is a mathematical curve that describes a smooth periodic oscillation.

### Sone

The sone is a unit of loudness, how loud a sound is perceived.

### Sound intensity

Sound intensity level also known as acoustic intensity is defined as the power carried by sound waves per unit area in a direction perpendicular to that area.

### Sound power

Sound power or acoustic power is the rate at which sound energy is emitted, reflected, transmitted or received, per unit time.

### Sound pressure

Sound pressure or acoustic pressure is the local pressure deviation from the ambient (average or equilibrium) atmospheric pressure, caused by a sound wave.

### Underwater acoustics

Underwater acoustics is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water and its boundaries.

### The list above answers the following questions

• What Decibel and Sound have in common
• What are the similarities between Decibel and Sound

## Decibel and Sound Comparison

Decibel has 146 relations, while Sound has 131. As they have in common 18, the Jaccard index is 6.50% = 18 / (146 + 131).
