Question

What is meant by noise?

Answer 1

Noise is an unwanted vibration considered unpleasant, harsh, or disruptive to hearing. Noise is not the same as desired sound, as both are fluctuations through a medium, such as a vacuum or water. The difference occurs when the brain experiences and recognizes a sound.

Complete answer:
Noise can indicate the unwanted remaining electronic noise signal that presents rise to acoustic noise heard as a buzz.
Noise exposure is associated with several adverse health outcomes. Depending on span and level of illness, noise may cause or raise the likelihood of hearing damage, high blood pressure, heart disease, sleep disturbances damages, and even reduced school performance. There are also causal connections between noise and mental effects such as annoyance, psychiatric diseases, and effects on psychosocial health.
Acoustic noise is a sound in the acoustic field, either slow-moving or unintended. On the other hand, noise in physics may not be clear to the human ear and may need detection devices. Noise has also been determined to be an occupational danger, as it is the most typical work-related pollutant. When connected with noise exposure at the workplace, noise-induced hearing loss is also called occupational hearing loss.
While noise-generated hearing loss is constant, it is also preventable. Especially in the workplace, arrangements may exist restricting permissible disclosure limits to noise. This can be particularly important for professionals operating in settings with constant exposure to loud vibrations. Examples of actions taken to stop noise-induced hearing loss in the workplace involve engineering noise control, the Buy-Quiet lead, the Safe-In-Sound award, and noise monitoring.
The concept of noise is primary to the sound of many vibrating modes, and it helps explain the spectra of oral sibilants. A quality of noise is that it has no periodicity, and so it produces no recognizable musical tone, sounding moderately like the static that is detected between stations of an FM radio.

Note: There is a distinction between sound and noise: Sound is described as the continuous oscillations that move from one medium to another. Sound has a positive impact on health. Sound provides a positive essence as it is audible, unique, relevant, and precise. However, noise is defined as an unpleasant sound that creates a disturbance. Noise hurts health like hearing impairment, hypertension. Noise provides a negative connotation as it is inappropriate, incompressible.
