In modern architecture and acoustic design, acoustic panels soundproof have become a key material for enhancing the quality of the acoustic environment. However, how to accurately measure its sound absorption is a challenge for many users and professionals. As a leading manufacturer of PET acoustic panels, we have introduced a new test method to help our customers assess the performance of acoustic felts more accurately.

New test method: Standardised acoustic tests

Our latest test method is based on the International Organisation for Standardisation (ISO) standard for acoustic testing and combines state-of-the-art measuring equipment and software systems. The testing process consists of the following key steps:

1. Environment preparation: Tests are carried out in an ISO-compliant acoustic laboratory to ensure that ambient noise and reflections minimise the impact on test results.

2. Sample Preparation: PET acoustic panels samples are mounted on pre-set test panels according to standard thickness and area specifications to ensure consistent test conditions.

3. Sound Source Setup: Highly accurate sound source equipment is used to generate sound of known frequency and intensity to ensure test accuracy.

4. Measurement and Recording: Multiple high sensitivity microphones are set up before and after the sound-absorbing panels samples to record the intensity and spectral changes of the sound, and calculate the sound absorption coefficient of the sound-absorbing felt by comparing the intensity of the sound at the sound source and the receiving point.

5. Data analysis: process the measured data with professional acoustic analysis software to evaluate the sound absorption performance of the sound-absorbing felt at different frequencies and generate a detailed test report.

Innovative Advantage: Improvement of Testing Accuracy

With this new method, we have not only improved the accuracy of the test, but also provided detailed frequency response and performance graphs, so that customers can clearly understand the performance of felt acoustic panels in different environments. This ensures that every piece of acoustic felt performs to the highest standards, providing reliable data to support your acoustic design.

Looking to the future: 

Continuing to push the boundaries of acoustic material technology

We are committed to continually advancing the technology of acoustic materials and improving the performance of our products. In the future, we will explore more innovative technologies to meet the ever-changing market needs. Our goal is to help every customer achieve the best acoustic environment through high-precision testing.
