Foam is widely used in architecture and interior decoration, such as acoustic panels, soundproof boards, and soundproof pads. These materials can reduce noise propagation, improve indoor comfort, and lessen the impact of noise on people.

In audio equipment like speakers, headphones, microphones, etc., foam is commonly used for internal soundproofing and noise reduction. It reduces resonance and noise interference, providing clearer and purer audio output.

Foam can be applied to soundproof mats, engine compartment soundproofing materials, and interior components in automobiles and other transportation vehicles. It effectively isolates the propagation of noise from inside and outside the vehicle, offering a quieter driving experience.

In some noise-sensitive electronic products like audio devices, recording equipment, and computer hard drives, foam is used for internal soundproofing and noise reduction. It reduces noise generation and propagation, enhancing the product's sound quality and performance.

In industrial machinery, foam is used for soundproof enclosures, soundproof hoods, and isolating pads for machines. It reduces the noise and vibrations generated during machine operation, providing a quieter working environment and reducing noise exposure to personnel.
