Why carbon fiber composite sheets can provide sound insulation

April 12, 2024

1. Audio frequency response: Carbon fiber board has different sound insulation effects on sound waves of different frequencies. In general, carbon fiber board has a good absorption effect on high-frequency sound waves (such as human voice, mechanical noise, etc.), while its sound insulation effect on low-frequency sound waves (such as heavy machinery noise, low-frequency vibration, etc.) is relatively poor.

2. Multilayer structure: The sound insulation effect can be improved by using multi-layer carbon fiber sheet or combining carbon fiber sheet with other sound absorbing materials (such as foam, insulating materials, etc.). Multilayer structures can increase the reflection and absorption of sound waves between different material layers, thereby reducing noise propagation.

3. Air isolation: The surface of carbon fiber plate usually has a smooth feature, which helps reduce the propagation of air flow and vibration noise. By applying sound-absorbing coatings on the surface of carbon fiber plates or using special surface treatment methods, the sound insulation effect can be improved.
