Introduction to Acoustic Performance
Noise is defined as an unwanted and disturbing sound, such as the buzzing from a moving car or a drill. Acoustic comfort refers to the psychophysical condition of well-being experienced in an environment where noise is limited. The measurement of Reverberation Time (RT60) is crucial for assessing acoustic comfort, as it indicates the time required for sound to become imperceptible. High reverberation times are associated with noisy environments, often due to reflective materials or irregular geometric shapes.

Measuring Sound Absorbency
The efficiency of an object's sound absorbency can be measured by comparing the RT60 of an environment with and without sound-absorbing objects. The formula used is RT60 = 0.161 x (V/A), where V is the volume of the space and A is the cumulative Equivalent Sound Absorbing Area of all surfaces and objects. The Sound Absorption Coefficient (α) is used to determine the sound-absorbing properties of a material, with values ranging from 0 (all sound reflected) to 1 (all sound absorbed).

Testing Environment and Results
The Axolight lamps were tested in a room measuring 7m x 7m x 6.1m (300 m³). The initial RT60 was measured across various frequencies, and reductions were observed with the addition of 1, 2, or 3 lamps. The results showed significant reductions in RT60, indicating improved acoustic performance. For example, with three lamps, the reduction in RT60 ranged from 29.3% to 47.1% across different frequencies.

Product Performance
Several Axolight products were tested, including SPLAYA, SPLAYB, SPLAYC, SPLAYD, SPLAYE, and SPLAYF. Each product demonstrated varying levels of acoustic performance, with reductions in RT60 and corresponding increases in the Equivalent Sound Absorption Area (A) per lamp. The performance varied across different frequencies, with higher reductions observed at higher frequencies.

Conclusion
Introducing sound-absorbing objects, such as Axolight lamps, into an environment can significantly enhance acoustic comfort by reducing reverberation time without requiring structural changes. The effectiveness of these objects is determined by their material properties, size, and shape, as well as the specific acoustic characteristics of the environment.

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.
