WHAT IS NOISE?
What is noise?
The difference between sound and noise is that noise is often described as unwanted sounds. Such sounds are perceived as annoying and annoying or may be directly harmful to hearing. Indeed, the subject “What is sound” and n What is noise tamamen is purely personal and is determined by the response to the noise source.
Reducing or eliminating noise at work often results in very efficient results. When the work environment is safer and healthier, the employer's obligation to finance the costs of absenteeism or accidents or workers who are not able to work at full capacity will be reduced. A good sound environment requires a preventive, stable and long-term approach to noise injuries. And achieving the goals is always the responsibility of the employer.
Noise and sound tones
Noise may consist of a single tone only, but usually consists of several tones of varying forces. The disturbing effect of a sound does not depend solely on the strength of the tones; frequency also has an effect - high tones are more disturbing than low tones. Pure tones are more disturbing than mixed tones.
When considered as a noise sound, it is often used for levels that do not make sense and exceed a certain height. When approached in this way, any sound that has reached a high level is noise. On the other hand, for example, a dialogue between two people may be perceived as "noise" by a third person who does not participate in the conversation. Dog barking, loud music played by the neighbor, car sounds from the road, or aircraft heard in a rural area can also be considered "noise".
Noise in compressed air systems is often seen in industry. There are two types of blowing noise. The first is the friction noise that occurs at the place of automatic valves and cylinders. The second type occurs where compressed air is used to blow, clean, cool, transport and sort out something. Blowing noise occurs at the point where compressed air is emitted from the system. It is of high speed and is usually formed by an open pipe or bore. It creates turbulence as the air spreads freely, producing loud noise.
Noise can make communication between people or electronic devices difficult or impossible by blocking the message being transmitted, changing the meaning of the message, or even distorting it.
Noise is described as unpleasant, unwanted, disturbing sound. While sound is a measurable and objective concept whose existence does not change depending on the person, noise is a personal, subjective concept.
Noise pollution (acoustic pollution), which is among the environmental problems, emerged as a result of the industrialization process in developed countries and in the form of technology surplus and became a major area of interest for various segments of the society after 1960s, especially transportation noise.
