How does the density of the felt acoustic panels affect the sound absorption?

As a manufacturer of polyester fibre Acoustic Panels, we are often asked about the effect of density on the acoustic performance of PET Acoustic Panels. Today, we're going to take an in-depth look at how the density of 3D Acoustic Panels affects their acoustic performance to help you make a more informed choice.

The density of a 3D Acoustic Panel is one of the key factors in determining its sound absorption. Here are a few of the important effects of density on sound absorption:

1. Acoustic performance:

   - Higher density PET Acoustic Panels: generally provide superior acoustic performance because their tighter structure is more effective at stopping sound waves from penetrating and reducing reflections. High-density materials are particularly good at controlling mid- and high-frequency noise.

   - Low-density polyester fibre acoustic panels: Although good at absorbing high frequency noise, they are less effective at absorbing low frequency noise. Its structure is looser and may not be able to effectively block the transmission of low-frequency sound waves.

2. Thickness combined with density:

   - Thickness impact: In addition to density, the thickness of the PET Acoustic Panel also affects its acoustic performance. High density 3D Acoustic Panels with moderate thickness usually provide better noise control across the full frequency range.

   - Consideration: When selecting a polyester fibre Acoustic Panel, a combination of density and thickness should be considered to achieve the best acoustic performance. For example, for locations where strong noise control is required, a high density, thicker 3D Acoustic Panel is a more appropriate choice.

3. Application Scenarios:

   - Indoor environments: In environments such as offices, conference rooms or home theatres, high-density PET Acoustic Panels can effectively reduce echoes and noise and improve the acoustic comfort of the space.

   - Specific needs: For recording studios, concert halls and other places that require high acoustic performance, choosing high-density 3D Acoustic Panel can achieve more precise acoustic adjustment.

4. Material selection:

   - Product type: There are a wide range of polyester fibre acoustic panel materials on the market, from mineral wool, glass wool to polyester fibre, and the density of different materials will affect their acoustic performance. Material properties and specific needs should be considered when choosing.

Understanding the effect of density on acoustic performance of polyester fibre acoustic panels will help you make a more appropriate choice for your acoustic design.
