Noise and Volume Sources
NOR 276
- The Nor276 is a high power loudspeaker with omnidirectional characteristics.
- Fulfils the following standards;
- ISO 10140-1:2010 (replaces ISO 140-3 Annex C (Laboratory measurements))
- ISO 16283-1:2014 (replaces ISO 140-4 Annex A (Field measurements)
- ISO 3382 Annex A (Reverberation Time measurements).
- The output power level is up to 120 dB re. 1pW for a pink noise signal.
- 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.

NOR 275
- Nor275 is designed for placement on the floor and uses the floor as a mirror for emitted sound.
- The loudspeaker is designed to operate at full power for more than one hour continuously.
