How to choose a car soundproofing

A large range of soundproofing materials requires utmost attention when choosing such a product. In this regard, many car owners have a question: how to choose the right sound insulation for a car. In this article, we will look at several main factors that you should pay attention to when choosing a Shumka. You can learn more about materials from the article Names of soundproofing materials, their purpose and manufacturers .

Key Factors

Perhaps we should start with the main factors of sound insulation:

• Mechanical Loss Factor (KMP);
• Specific gravity.

The first parameter is a relative value, measured as a percentage. The higher this indicator, the better, usually it ranges from 10 to 50%. The same applies to sound effects, only there this parameter is called the sound loss factor.

As for the second, it is generally accepted that the more weight, the better. However, today there are materials that have a good effect due to their technological characteristics (flexibility, internal design). For example, a reinforced vibration damper is considered effective if the thickness of its aluminum layer is 0.1 mm.

Additional factors

Let's move on to secondary values:

• Ease of installation. Use two materials (noise-insulating and vibration-insulating) or one universal one - this affects the budget. Trust the work to specialists or do it yourself, as an example: do-it-yourself car door soundproofing .
• Flexibility is also of no small importance. Flexible and elastic materials adhere better to the surface.
• The thickness of the material is also an important factor that affects where the material can be used. For example, in large areas or at joints.
• Material durability. You must pay attention to the warranty period or use third-party sources of information about this product.
• During the entire period of operation, the material should not change shape.
• The quality of the adhesive layer. When heated, the mastic should not lose its qualities, spread.

The price-quality ratio is one of the most important factors. You should not use expensive materials for a budget or old car and, accordingly, vice versa.
