Introduction of the solution
Acoustic Power Measurement
Acoustic Measurement System + Full Anechoic Chamber / Semi-Anechoic Chamber
- Measurement of acoustic power (acoustic strength) emitted from the test object.
- Construction of measurement environments compliant with relevant standards.
Intensity Method: JIS Z 8736-1, -2, -3/ISO 9614-1, -2, -3
Sound Pressure Method: JIS Z 8732, Z 8733/ISO 3744, 3745
Electroacoustic Measurement
Acoustic Measurement System + Anechoic Box / Full Anechoic Chamber / Semi-Anechoic Chamber
- Measurement of characteristics of electroacoustic devices such as speakers, headphones, VR goggles, and smart glasses.
- We provide not only measurement systems, but also a wide variety of measurement devices.
Full-range Head and Torso Simulator (ITU-T P.57 Type 4.3)
Various Microphones
Output Response, Frequency Response
Various Distortion Characteristics (Harmonic, Intermodulation, Difference Frequency)
Simplified Performance Measurement Using Anechoic Box + Sound Level Meter (Noise Meter)
Sound Level Meter + Anechoic Box
- Reliable sound pressure measurement with minimal setup effort.
- With the optional recording feature, captured waveforms can be analyzed in detail on a PC.
Applicable to automotive parts, electrical devices, and various drive components/products, such as:
Transmissions, Gears, Motors, Fans, Air conditioners
Sound Source Measurement / Localization Using Acoustic Camera + Anechoic Chamber
Acoustic Camera + Anechoic Chamber
- By using a sound source localization device that visually captures the location and intensity of sound sources inside an anechoic chamber, it is possible to perform advanced measurements in an environment free from sound reflections and external noise interference.
Applicable to:
Automobiles, Aircraft, Power tools, Household appliances, Wind turbines
VSAC + Pass-by System and Related Products
- Pass-by noise (exterior vehicle noise) refers to sounds generated by vehicles during operation or while passing by.
We offer various pass-by noise measurement methods and environments, both indoors and outdoors.
VSAC + Various Measurement Instruments

-
03
Proposal and Quotation Free
We will provide documents related to the quotation from Moritani Shokai, including: Quotation, Specification sheet, Concept drawings, Proposal document, Measurement and survey report
(These documents are generally provided free of charge up to this stage.)
-
04
Contract
If you decide to proceed with the contract, we will carry out all necessary steps including the execution of relevant contractual documents, arrangement of manufacturer products, design and fabrication, and final delivery.
-
05
Performance Verification, Inspection, and Handove
After product delivery is complete, we will verify the guaranteed values. If, by any chance, the acoustic performance does not meet the guaranteed specifications, we will implement secondary countermeasures at no additional cost until the guaranteed values are achieved.
We will also conduct all necessary delivery inspections (including dimensional and quality checks). Once all processes are completed, we will submit the final documentation.Upon your approval, inspection and handover will be carried out.
