Options

NX-28WR

The NX-28WR allows the NA-28 to record audio waveforms during regular level logging as well as frequency analysis.

This allows the user to listen to specific events that occurred during the course of the measurement as well as use Rion’s audio post processing software package AS-70.

NX-28FT

This program card adds FFT analysis capability to NA-28, with an analysis frequency range of 20kHz and 8000 analysis lines.

NX-28BA

This program card is used for simple and easy measurement of airborne and floor impact sound insulation of buildings and reverberation time.

Data is stored as text files. When used in conjunction with with waveform recording card NX-28WR, audio waveforms can be recorded during the reverberation time measurement.
