How many dB can damage your ears?
Human ears can only perceive a certain amount of noise. The human ear, which is quite weak today compared to a dog or cat, only perceives sounds between 0 dB and 140 dB. In these ranges, sounds between 120 and 140 dB cause serious damage to the ear and cause pain. To understand the DBS stated here more clearly, we have given the average dB levels according to the environments. You can see it below:
- Average sound level in the library environment 35 dB
- Sound level in the bus or subway 85 dB
- Sound level in areas where construction activities are held 105 dB
As you can see, the harmful effect of noise on human health is increasing exponentially.
Is Noise Covered By Occupational Disease?
Did you know that noise is one of the occupational diseases?
Noise, which has very negative effects on human health, has been put into circulation as an occupational disease. And noise is a fairly common occupational disease. The number of people who experience hearing loss due to noise every year is over 200,000. Also, noise is a type of environmental pollution that affects our daily life very badly.
This problem, which is generally experienced in big cities, increases with the experience of technological developments, and the noise will continue to increase as automation increases.
Even in Europe, where most of the developed countries are located, more than 15 million people are exposed to noise every year. This noise above 65 decibels causes psychological disturbances in people. At the same time, this amount of noise decreases the tolerance level of people and affects human relations negatively.
If we list the negative effects of noise on our health;
- It causes us to have hearing problems.
- It causes both physical and psychological disorders in people.
- Decreases work efficiency.
- Especially if there is heavy noise close to schools, it affects students’ success negatively.
- It decreases the person’s perception level.
- Nervousness and stress are seen at very high levels in people.
- It increases the rate of a heart attack in people with sudden increases in noise.
The unit of sound that can be perceived by the human ear is measured in Hertz. Hertz is the number of vibrations generated by the phoneme, and this vibration frequency creates the frequency.
The amount of sound that the human ear can perceive has been determined as 20 to 20,000 Hertz. A sound tone below 20 is called infrasonic sound, and a tone above 20,000 is called ultrasonic sound.
If you do not want a sound to damage your hearing organ, you should stay away from noise between 85 Decibels, that is, 100 to 10,000 Mhz.
The high rate of noise, especially in hospital intensive care units, causes adverse effects on the patient. Therefore, the quieter the intensive care rooms are, the higher the rate of recovery of the patient.
Noise-induced hearing loss occurs when someone is exposed to noise above 85 decibels for an extended period (although it varies from person to person). Noise between 120 and 140 decibels can actually cause pain in the ears.
What are the factors that create noise pollution?
Because a very high noise level is a sound that harms the natural life balance for humans or animals, we define it as noise pollution. The annoying outdoor noise is largely caused by machinery, construction activities, and transport such as motor vehicles, airplanes, and trains. Besides, other city sounds such as clubs, leisure centers, and outdoor social events also contribute to noise pollution.
The oldest known definition of noise is unwanted noise. However, we must define noise as any sound that affects people’s health. This definition is more consistent with definitions of other types of pollution, including air pollution.
In most developed countries, water and air are cleaner than they were 30 years ago; however, noise pollution is increasing.
To reduce the bad effect of noise pollution on our lives, all we have to do is use a noise barrier.
Purposes of Noise Barrier
- Prevents road noise.
- It prevents traffic noise from spreading into the city.
- Protects residents from factory noise if installed around the factory.
- It prevents the person from getting tired physically and psychologically.
Of course, the most important point here is human health. Noise has a disturbing effect on the heart and nervous system. Therefore, people cannot be exposed to noise throughout their lives. People who are constantly exposed to noise have a more aggressive and irritable nature. This is a scientifically proven fact. Therefore, if we do not want to face such a bad situation, we can protect our homes and regions in the city from the harmful effects of noise.
Quiet and protective noise walls are a maintenance-free alternative in the noise-canceling industry. It is a great advantage that it does not require maintenance. Because it does not require an extra cost. With a single expense, you can protect your home, office, or environment from the noise of the city. Thanks to the sound insulation curtain, your life will become easier and stress-free.
As you can see, highway noise barriers are a good solution that can make your city life easier. Who wouldn’t want to have a more peaceful life at a lower cost? Thanks to the sound barriers, you will have this comfort and you will be able to catch the quiet environment you want in your work areas and at home. When you come home from work in the evening, you will not be tired more with the sounds coming from outside. This is the biggest of the advantages of sound barriers.
