Sound insulation box is the isolation of external noise interference in the box, the internal use of sound-absorbing sponge tip to achieve anechoic rooms and special sound absorption structure, the minimum cutoff frequency for the 40Hz, can reach more than 99% absorption characteristics. Applicable to the measurement of acoustic parameters of electro-acoustic products, and a variety of mechanical, electrical, light industry products such as household appliances determination and scientific experiment.

A measure of the standard sound absorber:

1, sound-absorbing device noise elimination performance; ( the amount of noise reduction and frequency spectrum characteristics )

2, sound-absorbing device of aerodynamic performance; ( pressure loss etc. )

3, sound-absorbing device structure performance. ( size, price, service life etc. )

Two dimensions: L360MMx W480MMx H450MM

The three connection port specifications

Access ports: BNC:8PCS

Data port: DB9DB251PCS

Four: internal noise characteristics of the noise is less than or equal to 20DB

External environment noise is less than or equal to 80DB
