From noise to acoustic comfort, how to do it? Noise is commonly identified as an unwanted and disturbing sound, for example buzzing (an incomprehensible and continuous hum) from a moving car, a drill, etc. Acoustic comfort is the psychophysical condition of wellbeing a person finds themselves in when they are in an environment where noise is limited. The measurement of Reverberation Time (RT60), or the time required for sound to become imperceptible, allows the acoustic comfort to be measured in any given environment: the higher the reverberation time, the greater the perception of sound.

Where we tested our products? Manuel Vivian from 0,32 to 4,63 Equivalent Sound Absorbing Area (A) The environment used to measure the sound-absorbing properties the Axolight lamps is shown below: This is how the reduction of sound in the room was calculated. Acoustic performance The Reverberation Times of the room, with sounds of varying frequencies emitted from an audio source, were measured, first without acoustic lamps, then with 1, 2 or 3 lamps added at a time.
