HFD-V100 Handheld Acoustic Image Camera Ultrasonic Sound Detector

We can find in our daily lives that humans use their eyes to collect information faster and more intuitively than any other organ. This is why in many industries, "visual" monitoring of complex processes is required.

At the same time, many technologies were invented that expanded areas of human vision that were generally invisible to the eye. Nuclear magnetic resonance imaging (MRI), X-ray machines, and infrared thermal imaging cameras are some examples of technologies that allow humans to "see" invisible matter. However, there are currently only some basic ways to measure noise, such as noise meters. What advantage would we have if noise could also be seen? What would everything around us "look" like through an acoustic imaging system?

HFD-V100 has been developed to visualize the applications of the world-renowned acoustic brand KM, such as compressed gas leakage, partial discharge detection in electrical machine, space tightness testing, etc., using acoustic visualization technology. The use of nearly a hundred high-precision digital microphones improves measurement sensitivity, and can measure signals in the ultrasonic frequency band of up to 96kHz. In addition, excellent performance can be achieved in detecting high-frequency noise, including BSR(Buzz, Squeak, Rattle) noise. The HFD-V100 acoustic imaging system is a new type of noise source identification, positioning and test analysis system. It uses a high-sensitivity digital microphone to visualize the collected sound on the screen in the form of a color contour map. Effectively measure the sound field distribution, the sound image and the visible light video image are perfectly superimposed, forming a detection effect similar to that of a thermal camera on the temperature of an object. It can quickly identify and locate steady-state, transient and moving sound sources, help people intuitively understand sound waves, sound fields, and sound sources, understand the locations and causes of noise generated by machinery and equipment, and then find ways to manage and control noise.

Technical Specifications

Other more application fields:

Environmental noise monitoring, machine noise control, acoustic measurements in indoor or open environments, etc., can all use the Acoustic Imaging System to measure the distribution of sound sources, taking advantage of its unique visualization of imaging measurements.

Monitoring and distribution of environmental noise in power plants, workshops, nuclear power plants, etc., marking the location and intensity of noise generation, and helping to find ways to eliminate noise.

Highway noise analysis: measuring the driving noise of cars, trains, and high-speed railways and analyzing the distribution of noise, which is beneficial to the design of sound barriers and the adoption of noise reduction measures. Monitoring the machine: After obtaining the feature database of various states of the machine

by building a database, the machine state can be monitored in real time.

Noise evaluation: used to evaluate the noise quality of power stations,transformers, locomo-tives, etc., to report equipment noise magnitude, frequency range, etc. at fixed points and quantitatively.

It is used to detect and analyze the sound distribution in the hall, and report whether the sound in the hall is uniform and whether there are acoustic dark areas in the form of a distri-bution chart; Fixed-point directional pickup of the speaking voice of a specific person can eliminate the interference of surrounding sounds and obtain clear speech of the presenter. The presenter no longer needs to carry a microphone.It is used to measure and evaluate the noise in a small-scale environment. It reports the noise intensity in the living area in the form of a distribution map, especially along the street, and specifically measures the intensity of each noise source (processing plant, experimental field,etc.) near the living area.
