Scene Demand
Modern cars incorporate extensive weight-saving designs to meet weight reduction requirements, resulting in a significant reduction in the weight of structural components such as the body panels, chassis and frame, which were previously much heavier. Whilst this reduces the vehicle’s weight and energy consumption, it also leads to a substantial decline in sound insulation performance. Damping felt can effectively counteract structural noise and vibration caused by metal and plastic components, whilst sound-absorbing foam can effectively absorb noise and reduce noise energy; the combination of the two can significantly enhance a vehicle’s sound insulation performance. Furthermore, owing to its superior damping properties across a wide temperature range, damping felt can shield against various interference signals caused by vibrations, thereby effectively ensuring rapid and precise detection by the vehicle’s radar system. This technology is particularly well-suited for vertical and inverted applications, with typical use cases including the four doors, side panels and headliner. In certain specific circumstances, it may also be used in wheel arches and the boot, providing reliable assurance of the vehicle’s quietness and functionality.Noise-related disputes between neighbours in residential blocks are not uncommon. The main cause is the transmission of noise between floors or between adjacent flats due to inadequate sound insulation in the building. To resolve such noise issues, it is necessary to improve the sound insulation of floors and walls. Soundproofing felt can effectively enhance sound insulation, and when used in conjunction with sound-absorbing foam, it can significantly improve the sound insulation of walls, effectively reducing noise transmission and preventing noise-related disputes between neighbours.
Typical Acoustic Design
The walls are fitted with Silence Tech soundproofing felt and Silence Tech acoustic foam.It can effectively improve the sound insulation between walls, reducing the transmission of sound between different rooms within a property and through partition walls separating neighbouring properties, thereby preventing ‘eavesdropping through the walls’.
The flooring utilises Silence Tech sound-insulating and vibration-damping pads and sound-insulating feltThe use of silent sound-insulating felt and a sound-insulating, vibration-damping layer in flooring can effectively reduce vibrations caused by heavy objects on the floor, as well as the transmission of sound between floor slabs. Even if children are jumping or bouncing a ball indoors, this will not cause any disturbance to the flat below, thereby effectively enhancing sound insulation between upper and lower floors.
Silence Tech sound-absorbing fiber wool and damping sheets are used in the vehicle chassis, doors and other componentsAs modern cars undergo continuous lightweighting modifications and design changes in the pursuit of reduced energy consumption, this has led to a reduction in the weight of the body structure whilst simultaneously causing issues such as increased vibration in the body panels and a decline in sound insulation performance. The use of Mijings damping sheets and Mijings sound-absorbing foam can effectively enhance the vehicle’s internal and external sound insulation and sound-absorption performance, creating a quiet and comfortable ride experience.
