1. Product Specifications & Pricing

Egg Crate Acoustic Foam standard specification: 950mm × 6.5m × 20mm, available in densities of 20K / 40K / 80K. Price: ¥15 per square meter.
A roll material with a wave-shaped, embossed sound-absorbing surface, mainly used to eliminate indoor echo and suppress standing waves. Widely applied in recording studios, live-streaming rooms and equipment rooms for acoustic treatment.

2. Performance Advantages

1. Embossed wave sound-absorbing structure: the egg-shell-like wavy surface increases the contact area for sound waves, efficiently absorbing mid- and high-frequency sound, weakening indoor standing waves, reducing echo and reverberation, and optimizing the listening environment.

2. Multiple density options: three densities — 20K, 40K and 80K — can be selected according to noise intensity. The higher the density, the better the sound absorption performance and the stronger the resistance to sagging.

3. Flexible roll material, easy installation: supplied in full rolls and can be cut freely to any size. The self-adhesive version can be applied directly to walls and ceilings, making installation simple and the construction period short.

4. Shock absorption and cushioning: provides a certain buffering and vibration-damping effect. It can be used for wall sound absorption or wrapped around equipment enclosures to reduce noise reflection.

5. Moisture-resistant and anti-aging: the material does not readily absorb water, is not prone to mold or insect damage, and does not easily pulverize during long-term indoor use.

6. Compatible with complete acoustic systems: often used together with soundproof panels, soundproof felt and light steel keels. It mainly solves indoor reflected noise and is not used on its own as a sound insulation material.

3. Detailed Application Scenarios

Residential / Indoor Use

1. Home spaces: walls and ceilings of home theaters and private piano rooms, eliminating echo and improving the listening experience.

Commercial & Entertainment Venues

2. Live-streaming rooms, recording studios and broadcasting studios — reducing room echo and improving recording quality; KTV rooms and chess/card rooms for auxiliary sound absorption and noise reduction.

Offices & Public Buildings

3. Offices and meeting rooms — reducing noisy echo in the space and optimizing the environment for conversation.

Industrial Equipment Noise Control

4. Equipment rooms and the inner walls of control cabinets — absorbing equipment operating noise and reducing noise reflection.

Cultural Tourism & Other Scenarios

5. Practice rooms, small rehearsal rooms and other spaces undergoing acoustic renovation.

Note: the core function of egg crate acoustic foam is to absorb indoor reflected sound and eliminate reverberation; its ability to block external noise through a wall is weak. To achieve room sound insulation, it must be installed together with soundproof boards and a keel cavity system.
