What is Sound?
Sound is that phenomenon that involves the propagation of mechanical waves, which may or may not be audible, through a fluid generating vibrations in a body. For sound to be audible to our ears, it must consist of sound and acoustic waves generated by oscillations in the air, these are converted into mechanical waves in the human ear and translated by the brain.
The propagation of sound involves the transport of energy without the transport of matter in the form of mechanical waves propagated in solid, gaseous, or liquid elastic media. Sound does not propagate in a vacuum. The physics of sound is studied by acoustics, which evaluates the propagation of waves in different media and the interaction of these waves with physical bodies.
What is Noise?
It is all an unpleasant auditory sensation that is in the middle. It is usually classified as anything that is annoying to the ear. It is an unwanted sound. Noise is any unwanted sound that interferes with communication between people and their activities. When it is called noise as a synonym for acoustic pollution, it refers to a sound of high intensity that can be harmful to human health. In the case of excessive noise, earplugs are used to prevent hearing loss.
Sound vs Noise
Difference between Sound and Noise
Sound is the phenomenon that involves the propagation of waves in a medium and can be audible or not. It can be harmonious and follows a distinguishable pattern. Noise is any unwanted sound that does not follow a distinguishable pattern. For physics, sound is a set of waves that are diffused as a physical state. The noise is irregular between the fundamental tones and their harmonics.
