Metroacustica PXI System
This system is based on a generation / measurement PXI 4461 board developed by National Instruments manufacturer. The system uses software developed in LabVIEW language that works in conjunction with the hardware for signal generation and acquisition.
The PXI system offers proprietary software for calibration of the following equipment:
- old sound level meters - software "IEC60651pxi.exe"
- new sound level meters - software "IEC61672pxi.exe"
- sound exposure meters - software "IEC61252pxi.exe"
- noise dosimeters - software "ANSI_S125pxi.exe"
- sound level calibrators - software "IEC60942pxi.exe"
- measurement microphones - software "IEC61094pxi.exe"
Metroacústica DS System
This system is based on the use of a Stanford Research Systems 360 stand-alone generator.
The system uses software developed in LabVIEW language that acts in conjunction with the generator to generate the normalized signals.
The DS system offers proprietary software for calibration of the following equipment:
- old sound level meters - software "IEC60651ds.exe"
- new sound level meters - software "IEC61672ds.exe"
- sound exposure meters - software "IEC61252ds.exe"
- noise dosimeters - software "ANSI_S125ds.exe"
- measurement microphones - software "IEC61094ds.exe"
- band-pass filters - software "filtersDS.exe"
Metroacústica USB System
This system is based on the use of a 4431 USB device from National Instruments manufacturer. The system uses software developed in LabVIEW language that acts in conjunction with the device in order to generate/measure normalized signals.
The USB system offers proprietary software for calibration of the following equipment:
- old sound level meters - software "IEC60651usb.exe"
- new sound level meters - software "IEC61672usb.exe"
- sound exposure meters - software "IEC61252usb.exe"
- noise dosimeters - software "ANSI_S125usb.exe"
- sound level calibrators - software "IEC60942usb.exe"
- measuring microphones - software "IEC61094usb.exe"
Additional equipment is required to perform electroacoustic calibrations. See below the specifications of necessary equipment that can be supplied by two of the best companies in the segment of electroacoustics.
