CRY725D Pneumatic Acoustic Test Chamber
The CRY725D is a pneumatic, drawer-style acoustic test chamber that offers superior soundproofing at low frequencies compared to the CRY725 model. This makes it particularly effective for background noise measurement.
When combined with the CRY6151B and CRY algorithm, the CRY725D provides an enhanced solution for minimizing noise floor interference, making it an excellent choice for precision testing on production lines.
