Scope

GB/T 19887-2005 is the English-translated version of 声学可移动屏障声衰减的现场测量.

GB/T 19887-2005 — This standard specifies the movable barrier indoors or outdoors live sound attenuation performance evaluation method, the standard is the insertion loss measurement engineering -level approach, both with the actual measured sound source can also be used artificial sound source.

This standard applies to height and length greater than 1. 5m barrier, but as long as the parties agree can also be used for smaller barrier. Because the outdoor environmental conditions will affect the measurement.

Therefore recommended that the measured limiting barrier at a distance within the range of 25m. However, if the parties agree. Measurements can also be used for greater distance.

The results of the field test management differences. Therefore, different barrier performance can only be measured in the same position in the same way based on the data obtained compared Dacron.

This standard applies only to complete barrier does not apply to its constituent units components. Barrier components (eg panels, doors, windows) sound insulation and sound absorption shall be measured other relevant standards.

This standard does not apply to open office noise barriers and deal with community outdoor sound barrier.
