CRY7412 Ultra-Quiet Chamber

CRY7412 Ultra-Quiet Chamber

The CRY7412 is a manual ultra-quiet chamber designed for testing very quiet sounds while in a noisy environment. It is primarily used for audio and noise assessments of wireless electronic devices, both on production lines and in laboratories.

Featuring a unique design, the chamber consists of a smaller box embedded within a larger one, allowing for lateral opening in two stages. This innovative design enhances soundproofing and minimizes external noise interference, providing a controlled environment for accurate testing.

  • Minimized external noise interference
  • Superior performance
Sound Absorbing Lining

The acoustic chamber is equipped with a 40 mm foam lining, crucial for exceptional sound absorption. This premium foam minimizes both noise reflections and external disturbances, creating a controlled, quiet environment for precise acoustic measurements. Its broad frequency range effectiveness ensures high precision and consistent repeatability in test results, making it ideal for diverse acoustic testing applications.
