- Introduction to Our Solutions
- Acoustic Power Measurement
We measure the total amount of acoustic energy radiated into the air by the product (test object).
Like sound pressure level, acoustic power is expressed in decibels (dB) and represents the actual strength of the sound itself.
We offer acoustic measurement solutions, including both measuring instruments and acoustic environments such as anechoic chambers, for accurate acoustic power measurement.
- Measurement of acoustic power (acoustic strength) generated by 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
- Acoustic Measurement System + Full Anechoic Chamber / Semi-Anechoic Chamber
[Examples of Target Sound Sources]
Automotive components, electrical devices, and various drive system parts/products (e.g., transmissions, gears, motors, fans, air conditioners, etc.)
