What is noise? What are the hazards of noise?

  Cooling tower noise control, from a biological standpoint, as long as it is the noise that affects everyone's rest, study and work, that is, unused noise, it is generally called noise. When noise has adverse consequences on the human body and the surrounding environment, noise pollution is formed. In the 21st century with the rapid development of innovation and technology, everyone is living in noise, especially citizens in large cities or industrial parks, who have been suffering from noise. Therefore, the prevention and treatment of noise pollution is already imperative.I8oCooling tower noise reduction treatment manufacturer

  1. Definition of noise:

  What is noise? In layman's terms, the irregular sound can be interpreted as noise. First, we must first understand a basic element: decibels, decibels are the high and low units of sound pressure level (letter symbol: db), each time the sound pressure doubles, the sound pressure level increases by 6 decibels. 1 decibel is the sound that we can just hear in our ears. The sound within 20 decibels. Under normal circumstances, everyone thinks it is quiet. Naturally, people within 15 decibels can feel it belongs to "dead silence". .I8oCooling tower noise reduction treatment manufacturer

  20-40 decibels is probably the whisper in the ears of lovers. 40 to 60 decibels belong to everyone's regular conversation. Above 60 decibels belongs to the category of loud noises. At 70 decibels, everyone can feel that it is very noisy and gradually harms hearing nerves. Above 90 decibels will cause hearing loss, while staying at 100-120 decibels In the space, if there is no accident, we will have transient ear deafness (deafness) in one minute. Noise generally refers to these unpleasant and tiresome sounds. The noise waveform is messy.I8oCooling tower noise reduction treatment manufacturer
