Instruction Manual
Building Acoustic
Introduction
When equipped with the required program option(s),
Nor150 is well suited for measurement of building
acoustics in the form of measuring reverberation time
and sound insulation.
The Building Acoustics mode allows measurement
of building acoustics parameters according to the
ISO 16283 series of International Standards as well as
National Standards like DIN, BS, SS, SIA, etc.
Measurements are made in one-third octave bands
and the results are reported for each band as well as
frequency-weighted indices according to ISO 717-1
and ISO 717-2.
Full octave measurements are possible by selecting the
ISO 10052 standard.
The mode is entered by pressing
SETUP
followed by
Applications
