- EXAMPLE 1
-
Allows easy measurement of airborne sound in buildings (D value, L value etc.), and floor impact sound insulation performance measurement with a single instrument.
JIS and ISO compliant measurements and evaluation index calculation can also be performed with the NA-28 itself.
Data can be saved as text files, allowing use of an Excel macro for index calculation.
In addition, if the waveform recording card NX-28WR is also used, simultaneous sound pressure level waveform recording during measurement is also possible.
