Two (2) independent research and sound level testing studies have been undertaken to test the effectiveness of introducing an Acustico Lighting product. The following information sources were used:
AS/NZS 2107:2016- Acoustics—Recommended design sound levels and reverberation times for building interiors
WELL Building Standard v1 2017, International WELL Building Institute
WELL Performance Verification Guidebook, v1, 2016, International WELL Building Institute
ISO 3382:20091, Measurement of room acoustic parameters – “interrupted noise method”.
RMIT, BUILDING 100, SCHOOL OF ARCHITECTURE
Conducted by Resonate Acoustic Consultants using 2 x Opera 900mm and 1 x 600mm pendants
Reverberation time measurements were undertaken in general accordance with the procedure outlined in ISO 3382:20091, “interrupted noise method”.
Measurements were taken using two source positions, with three reverberation
decay times measured for each source position. Measurements were taken over 2 days, the first with no acoustic treatment and the second after the Acustico lights had been installed.
The results were then arithmetically averaged for the reported result.
OFFICE, EDUCATION & CAFE
Conducted by Building 4 Impact (B4I) using the 900mm Round Punk Light.
The methodology and equipment used to conduct the testing was informed by Australian Standards AS/NZS 2107:2016 Acoustics, and the WELL Performance Verification Guidebook v1: Test for building interior noise levels.
The results of the tests in the existing conditions of the buildings were compared with the tests conducted after introducing the lighting product in the same space.
The results show, the product reduces up to 30% of mid-frequency/ conversational noise and up to 45% of high/ background frequency noise in the surrounding environment.
Overall, some amount of sound attenuation was achieved in all the measured frequencies after introducing the product. This suggests the product can aid in absorption of sound in various built environments.
