What are the definition of noise and its effects?

We always hear about the noise, and we feel disturbed by it. But what is the exact definition of noise? Can we define all the loud sounds as noise? As Hatko Company, we are dealing with noise for so many years with our innovative products. So we want to define our enemy in this article. We will give you all the important and useful information about noise in this article.

What is Noise

What is Noise?

So what is the definition of noise? As the simplest saying, noise is an unwanted voice that disturbs our ears. The most important feature is that it is loud and unpleasant. But all loud voices can’t be defined as noise, at least for everyone. Noise is relative. For example, while someone finds loud music as noise, some others may like it and don’t accept it as noise. So, the noise should be loud and disturbing.

Noise has so many bad influences on our daily life. It directly affects our performance, peace, and health. That’s why we define it as a kind of pollution. The loud noise from industrial facilities, factories, highways, motor vehicles, airplanes are examples of noise pollution in today’s modern city life.

What is Noise Related Hearing Loss

What is Noise-Related Hearing Loss?

We can define hearing disabilities that are caused by noise as noise-related hearing loss. This unwanted disorder can be temporary or permanent. The normal level of sound from TV, music, traffic, and other voices can’t harm human health if there are no other hidden or known causes.

But some other high-level sounds like an explosion, or a continuous machine in a factory can give serious damage to our hearing ability. Especially people who have to work in these kinds of conditions suffer serious problems with hearing. These people should use protective equipment all the time.

So what is a noise level? We measure the sound with the decibel (dB). We grade all kinds of voices with dB. The sounds that we can hear range from 0 dB to 180 dB. 180 dB is the level of a sound like a launching rocket. Now we will talk about the harmful noises.

How Much dB is Noise

How Much dB is Noise?

75 dB or lower-level sounds are not harmful to human hearing even if you expose them for a long time. But 85dB and higher sounds may be harmful if you hear them constantly or discretely but repeatedly. Some sounds that you encounter in daily life and their dB levels are like this;

  • Normal talking sound level of people: 60 dB
  • Shouting talking sound level of people: 80-90 dB
  • Whispering sound between people talking: 30-40 dB
  • Sound of heavy traffic: 85 dB
  • Sound of a motorcycle: 95 dB
  • The loudest sound of an mp3 player: 105 dB
  • Firework and gunfire sound level: 150 dB
  • The sound of a taking off airplane: 120-140 dB

The human ear can hear all the sounds between 20 to 20000 Hz. But we can’t hear sounds below 20 and higher than 20000 Hz. We define below 20 Hz. sounds as infra-sonic sounds, and higher than 20000Hz. as ultra-sonic sounds. On the other hand, the normal speaking sound level ranges from 500 to 2000 Hz. According to the international standards, the sound level that is harmful to human health is between 100 to 10000 MHz or 85 dB.

These are some technical definitions and limitations of the noise. Yes, we can’t stop the generation of noise, but we can prevent the harmful effects of it. As Hatko Company, we are doing this. Our motto is ” Silent cities, with innovative noise control”. We dedicate ourselves to the aim we simply express in our motto and work so hard to create the best products.
