The document reports on the sound absorption area of Nordgröna Reindeer Moss Panels, measured in a reverberation room according to ISO 354 and SS 25269 standards. The test was conducted on November 13, 2014, by Johan Jernstedt.
Test Specimen Details:
- Product: Nordgröna Reindeer Moss Panel
- Dimensions: 50x50 cm (510x510x85 mm for wall panel)
- Mounting: Type A, with 8 panels directly on the floor
- Measurement Area: 0.26 square meters per object
Environmental Conditions:
- Reverberation Room Volume: 15.1 m3
- Temperature: 15.6°C
- Air Humidity: 55%
- Air Pressure: 101.3 kPa
Sound Absorption Results:
The sound absorption area was measured across various frequencies, with key values highlighted:
- 63 Hz: 0.03 m2
- 125 Hz: 0.06 m2
- 250 Hz: 0.18 m2
- 500 Hz: 0.34 m2
- 1000 Hz: 0.44 m2
- 2000 Hz: 0.46 m2
- 4000 Hz: 0.48 m2
The graph scaling was adjusted from ISO 354 standards for readability due to the small size of each object.
Conclusion:
The Nordgröna Reindeer Moss Panels demonstrate varying levels of sound absorption across different frequencies, with higher absorption noted at mid to high frequencies.
