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.

Psyacoustic Test System
Psychoacoustics is the science of the relationship between physical quantities of sound and subjective hearing impressions. To examine these relationships, physical parameters, such as loudness, sharpness, roughness, fluctuation strength, are mapped to hearing-related parameters. Unlike the physical quantities, these hearing-related quantities – also referred to as psychoacoustic parameters – provide a linear representation of human hearing perception. The psychoacoustic test system, with interactive interface and user-friendly operations, analyzes psychoacoustic parameters effectively and conforms to the international standard ISO 532 Part B.

Torsional Vibration Analysis System
Torsional vibration analysis is the analysis of the torsional dynamic behavior of a rotating shaft system as a result of forced vibration. Excessive torsional vibration leads to very expensive failures such as damaged shafting, couplings, gears, auxiliary equipment, and more. Repair costs to such equipment can be very expensive. Preventing torsional failures requires adequate analysis over the equipment’s intended range of operating conditions. Jumho Electric torsional vibration analysis system acquires rotary speed signals, calculate the angular velocity fluctuation rate, and therefore obtain various waveforms, angular velocity and acceleration.

Rotating Machine Order Analysis System
Analyzing the health and behavior of rotating machine is a key application for dynamic signal analyzer. Rotating machines produce repetitive vibrations and acoustic signals related to rotational speed. These relationships are not always obvious with standard dynamic signal analysis, particularly with variations in the rotational speed. As is the secret to sort out all the many signal components that a rotating machine can generate.

Microphone Array System for Noise Source Identification
Noise source identification of large-scale machinery is a tough issue. If you don’t know the noise source, you cannot find out methods of improving you products. Microphone array, or acoustic camera, is an advanced technology for noise source identification in steady, non-steady, motion, or rest state. A microphone array system can display noise source distribution in real time, and identify the locations of noise source inside the equipment
