Have you ever installed acoustic foam but been disappointed with the noise reduction effect? In many cases, the problem is not with the material itself. The shape and thickness of the sound-absorbing foam are equally important. As a professional manufacturer of melamine acoustic foam, Henan Enda Company has summarized some melamine acoustic foam options for different frequency noises to help you effectively improve the overall acoustic performance.

Melamine sound-proofing foam is a widely used acoustic material. With its unique porous structure, it usually has a porosity of over 99%, which can effectively convert sound energy into heat energy, thereby reducing unnecessary reflections and echoes. To meet the needs of different acoustic scenarios, Henan Enda melamine foam company provides various customized shapes of melamine sound-proofing foam:

1. Flat melamine acoustic foam: A balanced solution for mid-high frequencie

Flat melamine acoustic foam is the most common and is a simple and economical choice. Its surface is smooth, and it is suitable for installation in areas that require large-scale sound absorption.

Generally speaking, the thicker the sound-proofing sponge, the better the sound absorption effect. Henan Enda Company recommends a 50-millimeter flat melamine sound-proofing foam board, which performs particularly well in the frequency range above 800 hertz and is suitable for controlling speech noise, mechanical noise, and general indoor reverberation.

It has also been proven that when the flat melamine foam is combined with a fitting panel cavity, the low-frequency performance can also be significantly improved. This makes the flat panel a popular choice for sound absorption in offices, home walls and ceilings, industrial equipment shells, and duct sound absorption systems.

2. Melamine acoustic foam pyramid: Enhancing acoustic processing efficiency

The pyramid-shaped melamine sound-proofing foam is one of the most popular acoustic sponges. It has a three-dimensional surface, which increases the contact area between the sound wave and the material. This design not only improves the sound absorption efficiency but also helps to scatter reflected sound waves.

For the pyramid-shaped melamine sound-proofing foam, Henan Enda Company's standard configuration includes an overall thickness of 35 millimeters (25 millimeter conical part plus 10 millimeter base) and 60 millimeters (50 millimeter conical part plus 10 millimeter base). Test data shows that the 60-millimeter conical panel can achieve a NRC value of nearly 1.00, meaning that over 99% of the incident sound energy is absorbed within its effective frequency range.

This structure performs particularly well in the frequency range above 500 hertz. In addition to the sound absorption effect, it can also reduce flutter echoes and excessive reflections, creating a more natural sound environment.

For this reason, pyramid-shaped melamine acoustic foam is widely used in recording studios, podcast studios, home theaters, streaming rooms, and music rehearsal spaces.

3. Wedge-shaped melamine sound-proofing foam: Better low-frequency performance

Wedge-shaped melamine foam is an excellent choice for low-frequency noise absorption. The progressive wedge contour allows the sound wave to penetrate the foam more deeply before being reflected, thereby increasing the effective absorption path and improving the performance in the low-frequency range.

The standard flat or pyramid-shaped panels usually lose efficiency below 200 hertz, but the wedge structure can extend the effective absorption frequency to approximately 125 hertz to 200 hertz. Professional acoustic wedges are typically between 100 millimeters and 300 millimeters in thickness.

Due to this characteristic, wedge-shaped melamine acoustic foam is often installed in soundproof rooms, acoustic laboratories, acoustic test chambers, and specialized research facilities.

Which shape of melamine acoustic foam should you choose?

The best acoustic solution depends on the main noise frequency.

Flat acoustic panels provide an excellent balance between performance and cost in industrial noise control and large acoustic processing projects. Pyramid-shaped panels have higher sound absorption efficiency and better sound diffusion performance, suitable for recording and entertainment spaces. The wedge-shaped panels exhibit excellent low-frequency response capabilities and are often used in environments with high acoustic requirements.

Thickness is also crucial. A 25mm panel is mainly designed for high frequencies, while panels ranging from 50mm to 100mm can provide stronger mid-frequency absorption effects. For low-frequency applications, a thicker wedge structure is usually required.
