SPHERICAL SURFACE FIXTURE
To measure the sound power level according to ISO 3745-2003, 20 measurement locations must be on the spherical surface and cover the sound source in the anechoic and hemi-anechoic rooms. But it’s difficult to attach 20 microphones on a tripod on the spherical surface
The development of the BSWA MF720 (and MF710) microphone installation. Specifically for such measurements, the MF720 was designed in accordance with ISO 3745-2003 that will attach 20 microphones on the spherical surface. MF710 is the installed version 10. Position according to ISO3745; ISO7779 and GB6882
MF720 / MF710 features:
- Microphone position 20/10
- The position and direction of each microphone can be adjusted to suit an amendment to the ISO standard.
- Lightweight, easy to assemble Easy to carry and easy to transport
