Audiology is the science that deals with noise and its impact on human health. According to the forecasts of recent studies, their consequences can be very dire. Constant loud noise can destroy human health. Here are just some of the consequences of its impact:
- impaired hearing or hearing loss
- headaches
- high blood pressure
- impaired concentration
- difficulty concentrating
Sound intensity is measured in units called decibels (dB). The sounds of nature do not have a harmful effect on humans, because the level of such a sound is only 20-30 dB. Whispering is 30 dB, talking is 40-50 dB, shouting is 75 dB. The louder the noise, the stronger its negative effect on the human nervous system. Sometimes a car noise reaches 55 dB, and running engine is 80 dB. Unfortunately, it is impossible to completely rid yourself of all loud sounds, but it is in your power to make sure that there are as few of them as possible.
Why is hearing loss due to noise?
Constant noise is as harmful as loud noises. Drivers, machinists, pilots and other representatives of transport industry are highly exposed to vibration and noise. Moreover, over time, they notice that they have lost their former hearing acuity. Why it happens? This is how our body adapts to living conditions, i.e. its defensive reaction to external irritation occurs. However, with this adaptation, the auditory system is damaged and degraded. Moreover, the decrease in hearing acuity is influenced by both the high level of noise and its constant influence. When the recovery resource is depleted in the body, then the effects of noise exposure will become irreversible.
The cardiovascular system is also susceptible to the negative effects of noise and vibration. In addition, an increase in blood pressure leads to stress. In every car, standard soundproofing systems do not cope with their task, so a full set of high-quality sound- and vibro- insulation is required. The installation of soundproofing materials becomes a necessity, and not just a recommendation, if the driver uses the vehicle regularly.
Because of good soundproofing, you get a comfortable ride and good health.
If the driver spends a lot of time in the car, then even a quiet but constant hum, squeaks and other noises negatively affect his health. It is unlikely that passengers want to spend a lot of time in a noisy and rattling car. To talk with fellow travelers, you have to raise your voice, and the music from the car audio system should sound louder than background noise. Such conditions are not only harmful to health, but also reduce travel comfort.
Affordable soundproofing materials Smartmat significantly increase the comfort of the trip, especially if you are the owner of low-end market car. The materials perfectly rid of a car from noise and vibration, and contribute to the thermal insulation of the engine compartment. You can install the materials yourself or you can contact a specialized company.
To get the maximum effect, it is necessary to install different types of soundproofing materials on several areas of the car: floor, arches, doors, trunk, ceiling, hood, etc. It is always pleasant to travel in such a car - the noise does not interfere with a pleasant conversation with a fellow traveler and does not interfere with enjoying your favorite melody. In addition, reliable soundproofing materials preserve hearing and health, which, as you know, cannot be bought for money.
