How are the sound absorption levels of 3D Acoustic Panels classified?

As a manufacturer of 3D Acoustic Panels, we are often asked how the sound absorption ratings of PET Acoustic Panels are classified. Today, we will answer this question in detail and help you understand how to choose the right 3D Acoustic Panel for your needs.

The sound absorption rating of a polyester fibre Acoustic Panel is a key indicator of its acoustic performance. Below are common methods of classifying sound absorption ratings and related information:

1. Sound absorption coefficient:

   - Definition: The Noise Reduction Coefficient (NRC) is a standard indicator of a material's ability to absorb sound, ranging from 0 to 1. 0 means no sound absorption and 1 means complete sound absorption.

   - Classification: PET Acoustic Panel is generally classified into the following classes of sound absorption coefficient:

     - Low Acoustic Absorption (NRC 0.1-0.3): Suitable for environments with low acoustic requirements, such as ordinary offices or houses.

     - Medium Sound Absorption (NRC 0.4-0.6): For environments with some need for sound control, such as conference rooms or restaurants.

     - High sound absorption (NRC 0.7-1.0): for environments with high demands on acoustic performance, such as recording studios, concert halls or cinemas.

2. Frequency Response:

   - Definition: 3D Acoustic Panel: Detailed classification of sound absorption of Pet Acoustic Panel

The performance at different frequencies can be described by its frequency response curve. Different materials absorb low and high frequency noise differently.

   - Classification: A high quality PET Acoustic Panel will usually have a balanced performance across the entire frequency range, and different products may have different sound absorption performance at high frequencies, mid-frequencies and low frequencies.

3. Application Scenarios:

   - Light Acoustic: Suitable for general residential or office use, mainly for reducing background noise and improving comfort.

   - Medium sound absorption: Suitable for public spaces that need to control noise and echo, such as restaurants, conference rooms, etc.

   - Strong Acoustic Absorption: Suitable for places with professional acoustic requirements, such as music studios, theatres, cinemas, etc.

When choosing the right 3D Acoustic Panel, it is important to take into account the specific application requirements and environmental conditions in addition to its sound absorption rating. Understanding the sound absorption rating can help you make a more informed choice to achieve the desired acoustic effect.
