Product catalog summary

Introduction to Acoustic Performance: The document explores acoustic performance, emphasizing the management of noise to achieve acoustic comfort, defined as a state of well-being in a noise-minimized environment.

Measurement of Acoustic Comfort: Acoustic comfort is measured using Reverberation Time (RT60), which is the time it takes for sound to become imperceptible. A higher RT60 indicates a noisier environment. The formula for RT60 is RT60 = 0.161 x (V/A), where V is the space volume and A is the cumulative Equivalent Sound Absorbing Area.

Improving Acoustic Comfort: Acoustic comfort can be improved by adding sound-absorbing objects, which reduce RT60 without structural changes. The Sound Absorption Coefficient (α) measures material absorption properties, ranging from 0 (all sound reflected) to 1 (all sound absorbed).

Testing Environment: The document describes a test environment for measuring the sound-absorbing properties of Axolight lamps, detailing room dimensions and tests with varying lamp numbers to assess sound reduction.

Results and Data Analysis: Detailed data shows RT60 reduction with 1, 2, or 3 lamps, including tables of percentage reduction across frequencies and Equivalent Sound Absorbing Area per lamp. The data demonstrates significant RT60 reductions, indicating the lamps' effectiveness in enhancing acoustic comfort.

Lighting Performance:

PLSK1502 and PLSKR150 lamps: 64 W, 7684 lumens.
PLSK1002NE and PLSKR100NE lamps: 48 W, 5763 lumens.
PLSKR070NE and PLSKR070 lamps: 16 W, 1921 lumens.

Acoustic Performance:

Initial Reverberation Time (RT60): Ranges from 1.65 to 2.75 seconds across 125 Hz to 8000 Hz frequencies.
Reduction of Reverberation Time (RT60): Varies by lamp model, with reductions from -6.8% to -52.5% depending on the number of lamps.
Equivalent Sound Absorption Area (A): Varies by lamp model and frequency, with absorption areas ranging from 0.30 m² to 5.08 m².

Conclusion: The document provides comprehensive specifications on the lighting and acoustic performance of various lamp models, highlighting their effectiveness in reducing reverberation time and sound absorption across different frequencies.

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? Vanessa Vivian to 3,55 Equivalent Sound Absorbing Area (A) The environment used to measure the sound-absorbing properties the Axolight lamps is shown below: 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. This is how the reduction of sound in the room was calculated.
