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.
Noise Floor
The acoustic chamber maintains an impressively low noise floor level of under 6.5 dBA, even amidst external noise levels up to 80 dBA. This capability ensures a tranquil and controlled environment for accurate acoustic testing, significantly reducing the influence of ambient noise on measurements.
Versatile Communication Interfaces
Providing versatile communication interfaces, the CRY7412 provides exceptional flexibility to meet various testing requirements. The chamber can support a maximum of six independent connector panels, which can be combined and selected according to the test requirements.
This exceptional level of isolation effectively shields against external RF interference, providing a clean and stable testing environment. Such performance is critical for precise measurements and testing of acoustic devices, as any external RF noise could compromise the accuracy of the results.
