After installing the sound-absorbing panel, a series of tests are required to ensure that it achieves the expected sound absorption effect. Here are several common detection methods:

1. Sound absorption coefficient test:
-The sound absorption coefficient is an important indicator for measuring the sound absorption capacity of sound-absorbing panels. The sound absorption coefficient can be measured using the reverberation chamber method or standing wave tube method under laboratory conditions.
-In practical environments, portable acoustic devices can be used for on-site measurements. These devices can emit sounds at specific frequencies and measure the absorption of these sounds by the sound-absorbing panels.

2. Measurement of noise reduction amplitude:
-Use professional noise measuring instruments to measure the noise level inside the computer room before and after installing the sound-absorbing panel. Multiple measurements can be taken at different locations to obtain more accurate results.
-By comparing the noise data before and after installation, the actual effectiveness of the sound-absorbing panel can be evaluated. Normally, after installing sound-absorbing panels, the noise level in the computer room should be significantly reduced.

3. Sound pressure level measurement:
-Measure the sound pressure level inside the computer room using a sound level meter. Measurements can be taken at different frequencies to evaluate the absorption effect of sound-absorbing panels on sounds of different frequencies.
-Comparing the sound pressure level data before and after installation can further verify the effectiveness of the sound-absorbing panel.

4. Measurement of reverberation time:
-Reverberation time refers to the time required for sound to decay to a certain level in a room. The reverberation time can be calculated by playing pulse sound in the computer room and measuring the time of sound attenuation.
-By comparing the reverberation time before and after installing the sound-absorbing panel, the impact of the panel on sound reflection and absorption can be evaluated. Usually, after installing sound-absorbing panels, the reverberation time will be shortened.

5. Subjective evaluation:
-In addition to objective measurement methods, the effectiveness of sound-absorbing panels can also be evaluated through subjective evaluation. Staff or users can enter the computer room before and after installing the sound-absorbing panel to feel the changes in noise.
-Subjective evaluation can provide feedback that cannot be measured by instruments, such as clarity and comfort of sound.

6. Combustion performance test:
-Although combustion performance testing is not a direct method for evaluating sound absorption effectiveness, it can ensure the safety of sound absorption panels. Combustion performance testing can be conducted using standards such as ISO 9705 and ASTM E84 to ensure that sound-absorbing panels do not produce large amounts of smoke and toxic gases in the event of a fire.

7. Water resistance test:
-If the computer room environment is relatively humid, a water resistance test can be conducted to ensure that the sound-absorbing panel can still maintain good sound absorption effect in humid environments. Water resistance testing can be conducted according to EN 12667 or ASTM C1104 standards.

8. Physical performance testing:
-Including testing of the strength, hardness, toughness, and other aspects of the sound-absorbing panel. Physical performance testing can be conducted through standards such as ISO 354 and ISO 10545-1 to ensure that the sound-absorbing panel has sufficient durability and stability.

Through the above methods, the installation effect of the sound-absorbing panel in the computer room can be comprehensively evaluated to ensure that it achieves the expected sound-absorbing effect and provides users with a quiet and comfortable working environment. If you encounter any problems during the testing process, it is recommended to consult professionals for guidance and assistance.
