Micro Perforated Acoustic in-depth Demand Report

Acoustical treatment materials can be roughly divided into sound absorption materials, diffusion materials and sound insulation materials according to their functions. Among them, the sound-absorbing material is not only the conventional sound-absorbing plate, but also the low-frequency trap which is usually used to absorb low frequencies. First of all, we need to know how the sound will continue to spread after it has spread to our common walls.







































Incident sound-reflected sound = sound absorption coefficient

Incident sound-transmitted sound = transmission loss

Some of the sound is absorbed by the wall and turned into heat energy.

From the above relationship, it is not difficult to find that sound insulation can only ensure as little transmitted sound as possible, but it does not necessarily have a good sound absorption effect.

sound absorbing material

Traditional sound-absorbing materials are porous materials, or the scientific name is acoustic resistance sound-absorbing materials. The essence of sound wave is a kind of vibration, exactly speaking, it is air vibration for the speaker system. When air vibration is transmitted to this sound-absorbing material, it will be gradually relieved by the fine pore structure and converted into heat energy.


















Generally speaking, the thicker the sound-absorbing material is, the more such small holes are in the direction of sound propagation, and the better the absorption effect of sound incident immediately or at a small angle is.

Diffusion material













When the sound is incident on the wall, some sound will exit along the geometric direction and continue to spread, but usually this process is not an absolute "specular reflection". If it is an ideal absolute reflection, the sound should exit completely in the geometric direction after passing through the surface, and the energy in the exit direction is consistent with the incident direction. The whole process does not lose energy, which can be understood as no diffusion at all, or more popularly as specular reflection in optics.

sound insulating material

The sound insulation and sound absorption properties of materials are different. Sound-absorbing materials often use the pore structure in the material. However, this pinhole structure usually leads to the transmission and propagation of sound waves. However, in order to prevent the sound from further transmitting from the material, it is necessary to reduce the cavity structure as much as possible and increase the density of the material.

Usually, the sound insulation performance of sound insulation materials is related to the density of materials. Buying high-density sound insulation materials can further improve the sound insulation performance of the room. However, the single-layer sound insulation material sometimes still has limitations. At this time, double-layer sound insulation treatment can be adopted, and additional damping materials can be added to the two-layer sound insulation material. However, it should be noted that the two layers of sound insulation materials should be avoided as much as possible to adopt the same thickness, so as to avoid repetition of coincidence frequency. If in the actual construction and decoration, the whole house should be soundproofed first, and then sound absorption and diffusion treatment should be carried out.

I. Case Background: The "Noise Troubles" of a CaféProject Location: A café in an urban commercial blockCore Problem: This café is located in a densely - populated area. It features a high - ceilinged loft design, with large - area glass doors, windows, and hard decoration materials, resulting in serious noise problems. The sounds of customers' conversations, the operation of coffee machines, and the noisy street outside overlap. During peak hours, the noise level in the café soars to 78 decibels, severely affecting customers' dining experience and their willingness to stay. As a result, both customer flow and the café's reputation have been continuously declining. II. Customized Acoustic SolutionMaterial Selection: Select the wooden - strip polyester - fiber acoustic panels that combine aesthetics and practicality. These acoustic panels are based on high - quality wood and PET, having excellent absorption of mid - low - frequency noise. With a natural wood veneer surface, they have a natural texture that perfectly integrates with the warm and retro decoration style of the café.Installation Layout: Install the acoustic panels on the walls in a full - covering manner. This not only ensures good sound - absorbing performance but also makes the decoration more beautiful. For noise - source areas such as the bar and the kitchen, increase the laying density of the acoustic panels to strengthen the sound - insulation and noise - reduction effect.III. Remarkable Renovation AchievementsAcoustic Optimization: After the installation of the acoustic panels, professional tests show that the noise level in the café stabilizes at around 42 decibels. Customers can talk softly in the café without any pressure, creating a quiet and comfortable social atmosphere.Commercial Value Enhancement: After the renovation, the café has seen a 30% increase in customer flow, and the average customer stay time has been extended by 40 minutes. The rating on the online platform has increased from 3.8 to 4.7, making it a popular leisure and check - in place in the neighborhood.IV. Customer Review"I originally thought the noise problem was difficult to solve. But unexpectedly, the acoustic panels have given the café a brand - new look. Now customers who enter the café all say the environment is quiet and pleasant, and our business is getting more and more prosperous!" - Café Owner

I. Acoustic Challenges in Spaces and the Emergence of Bamboo-Fiber acoustic panelsDuring the renovation project of a new campus of a certain university, the school faced formidable acoustic challenges. In traditional classrooms, severe reverberation caused by sound reflection muddled teachers' voices, making it difficult for students to grasp knowledge points accurately. Meanwhile, traffic noise around the campus and the din of other on-campus activities frequently disrupted the teaching rhythm, significantly affecting learning efficiency.


To address these issues, the school engaged in numerous discussions with the renovation contractor. Eventually, the contractor reached out to Toomel. Leveraging 12 years of expertise in sound-absorbing panel production, Toomel's business team meticulously analyzed and compared various solutions, taking into account the school's specific requirements, budget constraints, and the campus's geographical location. Based on this comprehensive assessment, Toomel recommended bamboo-fiber acoustic panels to the university's renovation contractor.
