Sound Intensity is the acoustic energy (power) which passes through a specified area at a certain point in sound field in a specified time.

Measuring the energy in 3D achieves to presume the position of sound source, obtain amount of radiation from sound source and direction of flowing acoustic energy which is passing through the measuring surface.

The Sound Intensity Analysis Software DS-0225 consists of the “Sound Intensity Analysis Function” and “Sound Source Probing Function”. The former captures the flow of 3D sound and visualizes its directions and amount with 3D displays, and the latter is mainly used for measurement and analysis of the sound source position.

 

Features

  • 3D microphone probe (MI-6420) which is unique to Ono Sokki (four microphones are placed in each apex of a regular tetrahedron) can measure 3D vectors at one time.

        *In use of 3D SI (Sound Intensity) probe (Three times of measurement in total at each point are required when using 1D SI probe.)

  • Exclusive sound pressure and phase calibrator (MI-0620) keeps the microphone probe to be high accuracy at anytime, which corrects sound pressure sensitivity and phase difference between microphones.

  • The DS-0225 is Windows-based measurement / analysis software with simple operation and does not take long time to learn.

  • Not only the frequency domain for contour, color, and vector mappings of each but also 3D spatial mapping can be obtained.

  • Mapping display has a function to paste an image of the object under measurement.

  • Obtained data are collected in one folder for easy and safety backup
