Nor250
Hemi-dodecahedron loudspeaker |
|
| |
A powerful
sound source designed for building acoustics measurements
per ISO 140-4 Annex A (Field measurements), ISO 354, ASTM
E-90, E-336. The source provides uniform sound radiation.
When used with the power amplifier Nor280 the high sound
power level ensures accurate descriptors in measurement
conditions that include high background levels, high sound
insulation properties and large room volumes. |

designed for environmental noise assessments and building
acoustics with a high dynamic range
Our
analysers comply with the following standards:
IEC 60651 type 1
IEC 60804 type 1
IEC 61260 class 1
IEC 225
ANSI S1.4-1985 type 1
ANSI S1.43-1997 type 1

Free-field
Microphone (GRAS 40AF) |
|
| |
The
key components that determines the accuracy of a sound
level meter is the measurement microphone and its associated
preamplifier. The effectiveness of these components in
converting the acoustic signal into an electrical analogue
set the maximum accuracy that can be achieved by the ensuing
signal processing. |

Tapping
Machine (NOR 211A) |
|
| |
A
lightweight and self contained sound source for making
measurements to the latest versions of the international
standards. (ISO140, EN 20140, ASTM E492, etc.) Used making
footfall noise transmission measurements in buildings
as set out in International and National Standards |

Acoustic
Calibrator – Class 1 (Nor 1251) |
|
| |
The
use of sound calibrators dates back to the days when it
was easier to design a stable sound calibrator than a
stable sound level meter. Today, sound measuring instruments,
in general, are as stable as the sound calibrators. However,
measuring microphones are very delicate devices designed
to fulfil very rigid specifications. This makes them vulnerable
and subject to damage unless care is taken. |
