CRY7412 Ultra-Anechoic Chamber

CRY7412 Ultra-Anechoic Chamber

The CRY7412 is a manual ultra-anechoic chamber designed for testing inherent noise under optimal soundproofing conditions, ensuring precise measurements. 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
Noise Insulation (SIL)

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.
