Where to go for sound absorption and noise reduction testing with complete solutions? BAIJIAN Materials Testing Agency provides sound absorption and noise reduction testing services. It is a national high-tech enterprise, a third-party materials laboratory, and a CMA qualification certification agency. It is a collectively owned scientific research institution with complete laboratory instruments. , a strong scientific research team, adhering to the concept of scientific research and dedication, engaged in performance testing, non-standard testing, unknown substance detection and identification, industrial problem diagnosis and testing, composition testing, failure testing, corrosion testing, etc. Test reports will be issued in 7-15 working days to support The QR code system checks authenticity, and multiple laboratory branches across the country support nationwide door-to-door sampling/sample delivery testing services.

Test period: 7-15 working days

Testing fee: Initial inspection of samples. After the initial inspection, a quotation will be made based on the customer's testing needs and the complexity of the experiment.

Sound absorption and noise reduction test range

Porous plates, wall panels, fabrics, bamboo, soundproof rooms, aluminum foil, steel structures, composite air ducts, sound-absorbing materials, etc.

Test item: Sound absorption and noise reduction test

Sound absorption and noise reduction test method

The sound absorption and noise reduction test method usually includes the following steps:

1. Prepare test equipment: use an acoustic absorption tester (sound absorption chamber/box), including a sound source, sound level meter, spectrum analyzer, etc.

2. Establish a test environment: Set up a test environment indoors or in a sound-absorbing room to eliminate external interference, such as closing room doors, windows and other sound sources.

3. Set parameters: According to the test standards, set the test parameters, such as the dynamic range and time of the sound level meter.

4. Test sample: Install the door core panel sample in a standard position before testing. It is necessary to ensure that the surface of the sample is intact. Various installation methods can be used.

5. Start testing: turn on the sound source and conduct the test. During the test process, the sound source volume needs to be controlled to maintain a certain sound intensity. A spectrum analyzer can be used to measure the frequency and frequency distribution of sound waves at the same time as the measurement.

6. Data analysis: After completing the test, collect test data and sample parameters, use some relevant tools, such as visualization tools, acoustic software, etc. to perform data processing and analysis, and evaluate the sound absorption and noise reduction effects of the sample. .

7. Result judgment: Compare the test results with relevant standards to determine whether the sound absorption and noise reduction performance of the sample meets the requirements.

When conducting sound absorption and noise reduction tests, test samples should be selected according to the required sound absorption and noise reduction performance standards, and appropriate test methods and instruments should be selected to obtain accurate test results.

What does the BAIJIAN test report do? What problems can it help you solve?

1. Sales report. (Sales need to provide third-party testing reports to make their products more unique, let the product data speak for themselves, and make customers more confident in the quality of their products.)

2. Research and development reports. (In the process of developing new products, we encountered some thorny issues about ingredients. We used third-party testing data to find the cause of the problem, solve the problem in a timely manner, shorten the R&D cycle, and reduce R&D costs)

3. Improve products quality. (Discover problems with your own products through comparison of third-party testing data, improve product problems, improve quality, and reduce production costs)

4. Use of scientific research paper data.

What are the advantages of BAIJIAN material testing laboratory?

1. Collectively owned testing institution with complete qualifications and scientific, fair and accurate test reports .

2. Multiple laboratory branches are located across the country, supporting door-to-door sampling/sending samples for testing.

3. The testing cycle is short, the testing cost is low, and the experimental plan is more complete.

4. For initial inspection of samples, no testing fees will be charged during the initial inspection.

5. The test report supports scanning the QR code to check the authenticity.

BAIJIAN testing process

1. Send samples. (Communicate with engineers, submit your own testing requirements and send samples to our research institute)

2. Initial inspection samples. (After receiving the sample, conduct a preliminary inspection of the sample and formulate a detailed experimental plan)

3. Quotation. (After the initial inspection, a quotation will be made based on the customer's testing needs and the complexity of the experiment)

4. Both parties confirm, sign a confidentiality agreement, and start the experiment.

5. It takes 7-15 working days to complete the experiment.

6. Mail the test report and provide post-service.

The above is the relevant introduction to sound absorption and noise reduction testing. If you have other needs, you can consult the laboratory engineer to help you solve it.
