Many motorists are dissatisfied with the fact that the interiors of their cars are too noisy. Excessive noises come from the tires, from rocks drumming on the wheel
When deciding to apply additional sound insulation, motorists usually do not think about how much the car will gain in weight after such an intervention. But a “noisy” car can add about 70 kg in weight! It all depends on the size and class of the car, and, of course, on the number of soundproofing mats installed in the body.
At the same time, an increase in mass will bring a number of problems. The most banal is the increase in fuel consumption. If the wealthy owner of a frame SUV can tolerate this, then the owner of a used crossover is unlikely. But above all, extra pounds will affect cars and sports cars. “Shumka” risks violating the weight distribution along the axles, which will have an adverse effect when driving at high speeds. In particular, the behavior of the car in bends will change and the braking distance will also increase. So a normal race on the track on a track day can end in a crash followed by a major overhaul.
Continue. The heavy doors and trunk lid will sag over time. As a result, not only rubber seals are rubbed, but also paint on metal. And the fastening loops and locks will loosen too. So the rumble will get louder. You will not only have to tear off the Shumka, but also make body repairs.
And it happens that after installing expensive sound insulation, the driver experiences discomfort. It becomes too quiet and a person begins to get irritated by such a silence with low-frequency sound. A soft hum distracts from the road, causes drowsiness and prevents you from focusing on driving. I want to open the window and hear the noises from the street.
The fact is that when installing soundproofing, it is important to calculate not only how much acoustic noise is reduced in decibels, but also its frequency. And they forget how to do it. But even at a low volume, a certain frequency range is amplified.
According to the AiF portal, citing specialists from the American College of Cardiology, there are a number of frequencies that have a harmful effect on the human body at a given sound power level. This is noise in the region of 60-70 decibels, which affects the heart muscle and, with prolonged exposure, increases the risk of heart disease.
But that is not everything. With such a loudness, dangerous frequencies, for example, for the abdominal organs lie within 25 Hz, and for the eyes – 60-90 Hz. That is, when vibrations of sound waves fall within this range, a person may experience nausea, and eye fatigue also increases.
