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.
