The egg crate shape of acoustic foam panels is often considered to have higher efficiency compared to other shapes due to its unique design and properties. Here are a few reasons why egg crate shape acoustic foam is often preferred:

Increased Surface Area: The egg crate shape features a pattern of peaks and valleys, which increases the overall surface area of the foam panel. This increased surface area allows for greater sound absorption capabilities. The more surface area available, the more sound waves can come into contact with the foam, leading to improved sound absorption and reduction of unwanted reflections.

Enhanced Diffusion: The irregular shape of the egg crate pattern helps in diffusing sound waves. When sound waves hit the peaks and valleys of the foam, they are scattered in various directions. This diffusion helps to break up the direct path of sound waves, reducing the occurrence of standing waves and echoes. By scattering the sound waves, the egg crate shape contributes to a more even distribution of sound energy throughout the room.

Versatile Placement: The egg crate shape allows for versatile placement options. The convoluted pattern can be aligned vertically or horizontally, depending on the specific acoustic requirements of the room. This flexibility enables users to experiment with different orientations, angles, and positions to achieve the desired acoustic treatment results.

Cost-Effective: Egg crate shape acoustic foam panels are often more cost-effective compared to other specialized shapes or designs. The manufacturing process for egg crate foam is relatively straightforward, making it a more affordable option for those seeking acoustic treatment on a budget.

It is important to note that while egg crate shape acoustic foam panels offer advantages in sound absorption and diffusion, their effectiveness can vary depending on the specific room and acoustic characteristics. In some cases, other shapes or designs, such as wedge-shaped or pyramid-shaped foam panels, may be more suitable for addressing specific acoustic issues or achieving desired sound quality goals. It is always recommended to consider the unique needs of your room and seek professional advice when choosing the right acoustic foam for your specific application.
