How and why is Hush tested?
Hush is scientifically tested
We carried out independent scientific tests to find out how effective the Hush acoustic light is at improving sound quality in a space. Tests were conducted to ISO 354:2005 standards in a controlled environment by qualified industry experts at the University of Canterbury. This standard describes methods for measuring the absorption of sound by single objects, such as the Hush acoustic light. This is measured across different sound frequencies.
How can Hush affect sound quality in a space?
Tests were designed to measure the amount of sound that is absorbed(as opposed to reflected) by the Hush acoustic light fixture, per m2. Sound is vibration, therefore when it meets a hard surface it is reflected back unless absorbed by a soft surface such as the fibrous acoustic material of the Hush light. When sound is absorbed the overall sound quality in the room improves.
The test also measured the amount of time it took for a sound to die away within the room. Called reverberation time (RT), this measures the amount of time after the sound source has been shut off that the sound reverberates in the room before disappearing.
If we can control the parameters relating to sound absorption and reverberation time, we can create a more comfortable acoustic environment for the people occupying the space. Tests can tell us whether Hush can effectively be used to do this.
