Sound and noise

The difference between sound and noise lies in the lack of harmony in the second . Sound obeys a distinguishable pattern while noise is an anomaly with no apparent patterns.

The word sound comes from the Latin sonitus which means noise or roar. It is only recently that we make a distinction between the two terms.

In physics , for example, they define sound as the set of waves that diffuse as a physical state (liquid, solid and gaseous) that causes variations in pressure and density , different from noise that is irregular and without agreement between the fundamental tones and its harmonics.

Sound can be distinguished from noise by its quality of pleasant or unpleasant . Sound is often used to describe something pleasant, such as the sound of rain or the sound of music. Noise is used to underline something that creates a violent impact, such as car noise or construction noise.

In phonetics, sounds are also differentiated from noises. Phonetics is made up of sounds produced by each organ, such as the vocal cords, the nose, etc. Instead, the use of onomatopoeia are noises produced to resemble an animal or thing.



The sound differ in three aspects: timbre, intensity and duration. The timbre is synonymous with the tone of voice, the intensity is the volume of the sound and the duration is the time.


Noise can be divided into three types: continuous, intermittent and impact noise. Noise, in the area of ​​telecommunications, communications and physics, is defined as a disturbance.

In telecommunications, noise is an anomaly in the signal, while in communications noise is the factor that prevents clarity to understand speech, and in physics, on the other hand, it is a segment of irregular waves.
