There are many types of windshields, each with a specific function. Today you’re going to learn about the acoustic windshield. certainly, this windshield is a trend among windshield manufacturers worldwide for its functionality so practical and desired by any consumer.
The acoustic windshield has a design to provide better concentration behind the wheel and greater comfort for the driver and passengers. Its special laminate reduces the noise level in the passenger compartment by up to 30%. Allowing you to converse with less effort. further, so, It also limits low-frequency hum, aerodynamic noise, and rain noise.
If you have doubts to buy an acoustic windshield you have to know these characteristics about it.
A comparison of standard windshield construction and an acoustic windshield shows that the thinner acoustic windshield is lighter than the thicker standard windshield.
The standard laminate has a surface density of 12.3 kg/m(3).
While the acoustic laminate has a lower surface density of 11.3/m(3).
Despite it’s lighter weight and thickness.
As well as reduced coincidence dip and less sound transmission at the high-frequency range, which largely is due to the high damping characteristics of the acoustic interlayer.
This is of particular significance since automotive windshield glazing is trending toward the thinner glass and, as a result, the transmission of wind noise is of increasing concern.
The plastic layer between the tempered glass sheets makes it more difficult to enter, as it provides a layer of elasticity between the glass plates.
As this study by wearshade says. The windshield seems to be an effective medium blocking UV radiation .
It is important to note, however, this windshields are an unique type. Laminated glass is made from laminated plastic between two layers of glass, giving to this windshield the feature of block 98–99% of all UV light.
That the Laminated glass is made by pasting PVB (polyvinyl butyral) resin glue film between two or more pieces of the glass sheet, then heating, pressing and bonding them together to create flat or curved compound glass product.
The glass sheet for making laminated glass can be ordinary glass, float glass, tempered glass, colored glass, heat-absorbing glass or heat-reflecting glass, etc.
