Anechoic Chamber
Wedge:The acoustic absorptivity of sound-absorbing materials used in anechoic chamber must be greater than 0.99. In anechoic chamber, gradient absorption layer, wedge or conical structure are often applied with glass wool and flexible foam as its sound-absorging materials. Anechoic Door: The design of rotatable door can affect the whole function of anechoic chamber. Therefore, it's crucial to combine steel plate and sound-absorbing cotton in the door, which is exactly our design.Acoustic Insulating Material:Applying high-density materials to enclose external noise. Damping materials: Using spring, rubber and cotton to enhance damping capacity.The Anechoic Chamber conforms to GB/T 6882-86 and ISO 3745 specifications.

Acoustic Calibrators
When you're ready to take noise measurements, it's strongly recommended that you perform a field calibration using an Acoustic Calibrator. You should calibrate your sound meter before you start to measure, and then once you've finished you should perform a reference check against the calibrator and make note of any drift that has occured. You can find out more about performing Field Calibrators by reading this post and watching a short video.

Acoustic Probe
AA-Ultrasonic
The AA-Ultrasonic acoustic probe is designed for use on air insulated terminations where a clear sound path between the electrically stressed insulation and the probe is present. The sensor is extremely sensitive and can detect activity below 10pC. The probe has a magnetic base to allow coupling to steel enclosures and a swivel head as so the detecting sensor can be aimed directly at the HV point. Corona in air and surface tracking can seriously damage high voltage insulating surfaces in a way that will ultimately lead to flashover and complete failure of the insulator. This discharge activity creates acoustic emission that can be detected using a high frequency sensor. The magnitude of the acoustic emission is indicative of the degree and severity of the discharge activity.
