There is, however, more to cabin noise than just noise transmitted from outside. In addition, pseudo-noise also impacts a vehicle\u2019s noise reduction. Pseudo-noise is caused by air turbulence vibrations impacting vehicles\u2019 windshield and windows. The turbulence is created as air passes over the hood, wipers, A-pillar, and side-view mirrors. Pseudo-noise can\u2019t be assessed using Sound Transmission Loss (STL) testing, the most common test method to measure the extent to which sound energy is reduced as sound passes through certain materials.<\/p>\n\n\n\n<p>Our NEW acoustic grade, <strong>SV grade<\/strong>, is developed to improve damping performance and significantly reduce noise caused by vibrations, which cannot be assessed through STL testing. Using the film in windshields and side windows can greatly enhance the cabin quietness and comfort, making driving a unique, luxurious experience.<\/p>\n\n\n<div class=\"c-button-type01 row justify-content-center\">\n\t<div class=\"col-lg-5 d-brochure-bg-btn is-inner-btn btn-size-medium\">\n\t\t<a href=\"\/en\/download\/SoundS\/\" target=\"_blank\">\n\t\t\t<button type=\"button\" class=\"btn btn-primary\">Download Brochure<\/button>\n\t\t<\/a>\n\t<\/div>\n<\/div>\n\n<\/div>\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n\t<\/div>\n\n\n<H2 class=\"c-title-level02 section-subtitle\">Application of Acoustic Glass<\/H2>\n\n<div class=\"c-layout-frame section-flame\">\n\t\t<div class=\"row align-items-center\">\n\t\t<div class=\"col-lg-6\">\n\t\t\t<div class=\"feature-img text-center\">\n\t\t\t\t\t\t\t\t<img decoding=\"async\" src=\"https:\/\/www.s-lecfilm.com\/wp-content\/uploads\/P1-Updated-Wind-Tunnel-1-1024x463-1-1024x463.webp\"  alt=\"Wind tunnel test using paranomic rooflite with S-LEC\u2122 Sound Acoustic Film\">\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t<div class=\"col-lg-6\">\n\t\t\t<div class=\"feature-cont\">\n\t\t\t\t<div class=\"acf-innerblocks-container\">\n<Div class=\"c-title-level03 feature-cont-title\">\n\t\tPanoramic Roof Glass<\/Div>\n\n\n\n<p>Environmental conditions such as wind friction and raindrop create noise experienced inside a vehicle.
