Optimal for rotation frequency ratio analysis.
When analyzing phenomena such as vibrations and noise, frequency analysis with respect to rotational speed or order can measure phenomena caused by rotational speed, such as the natural frequencies of structures or components.
Evaluation of the residential performance of buildings.
An architectural acoustics measurement system is used to evaluate the residential performance of buildings. This system can measure sound transmission loss, reverberation time, inter-room sound pressure level difference, floor impact sound (heavy/light), reduction amount, and sound absorption rate according to measurement methods aligned with JIS and the recommended measurement standards of the Architectural Institute of Japan.
Detailed understanding of the vibration phenomena of objects.
It is used for measuring the strength of wood materials (Young's modulus measurement), evaluating the rigidity of bridge piers, and measuring the natural frequency of materials.
For noise and vibration measurement of damping materials.
Vibration-damping materials such as damping steel plates, damping alloys, plastics, rubber, and asphalt are used in many fields, including automobiles, home appliances, and office equipment, effectively reducing noise and vibration. This system uses the multi-channel analysis processor SA-02, and with simple menu operations, it measures the frequency response function using either the cantilever beam method or the central excitation method.
It is important to measure not only the noise level but also the "acoustic power level."
The acoustic power level is used to express the loudness of sound emitted by machines. The acoustic power level represents the total energy emitted by the sound source. If we compare noise levels and acoustic power levels to earthquakes, the noise level corresponds to the intensity at various locations, while the magnitude corresponds to the acoustic power level. Just as the intensity at different locations is not determined solely by the distance from the epicenter, but also varies depending on the propagation path and ground structure, in the case of sound, the noise level varies due to the directionality of the sound source and the distance to the measurement position. Therefore, the acoustic power level is used, and particularly in Europe and the United States, it is necessary to specify the acoustic power level of equipment.
Measurement of acoustic power level of output products.
This system is a measurement system for acoustic power levels using the reverberation room method. It determines the 1/3 octave band and A-weighted acoustic power levels in accordance with JIS Z 8734:2000 (ISO 3741:1999), which specifies the precise measurement method for acoustic power levels of noise sources using the sound pressure method in a reverberation room.
For measuring "noise and vibration" at construction sites.
To preserve the living environment around construction sites, the Ministry of Land, Infrastructure, Transport and Tourism has announced regulations regarding the designation of "low-noise and low-vibration construction machinery." This announcement allows construction machinery that meets noise standards to display signs indicating "low-noise construction machinery" or "ultra-low-noise construction machinery."
Optimal for "sound-based quality judgment" on production lines with high levels of background noise, such as motor line inspections.
This is a system that enables quality judgment using sound on production lines with high levels of ambient noise, utilizing a surface intensity sensor (integrating a microphone and vibration acceleration pickup) and a multi-channel analysis processor SA-02. Additionally, it can be measured without using soundproof facilities (such as anechoic chambers or boxes), allowing for the construction of a cost-effective and efficient line inspection system.
