Noisy environments can affect our daily lives and work, especially for those with sick or elderly family members, where a quiet space is crucial. Over the past month, our neighborhood has been reported for disturbance several times, with the culprits being detained, which illustrates that people now prefer a tranquil living environment. Acoustic panels have naturally become a popular choice for home renovations. Many friends are unaware of their working principles, so today, I'll introduce the working mechanism of acoustic panels.Firstly, let's discuss the sound-absorbing materials. There are two types of materials used for sound-absorbing panels: the two-pore type and the fibrous type. Essentially, these two materials have no significant differences. The principle of sound absorption lies in providing pathways for sound to enter within the material itself. These pathways are composed of countless interconnected tiny holes. Some pathways are formed by a mixture of fibers crisscrossing and creating gaps. It is precisely because these gaps are excessively long and chaotic that once sound enters, it becomes trapped, much like a maze. If sound manages to enter, it struggles to escape due to the disordered and lengthy pathways, constantly bouncing around and gradually losing energy in the process, thereby achieving sound absorption.
All matter follows the law of energy conservation; the role of the sound-absorbing panels is to convert this energy into other forms.
