Sound power measurement with MF710 / MF720. They are hemispherical arrays developed by BSWA for sound power measurement.
MF710 meets the requirements of the 10-microphone method according to GB 6882 1986, ISO 3745:1977, GB/T 18313 2001 and ISO 7779:2010.
MF720 meets the requirements of the 20-microphone method according to GB/T 6882-2008 and ISO 3745:2012.
The MF710 / MF720 was developed as a small, lightweight and easy-to-mount bracket.
Microphones can be mounted on the hemispherical surface very quickly and accurately, making it very easy to comply with the standard requirements for sound power measurement.
