How Acoustic Absorption Works And When To Use It
So, what is absorption? Audio absorption reduces sound bouncing off surfaces, causing echo and reverberation.
Think of a sponge soaking up water; sound absorption works similarly, with materials absorbing sound waves. The effectiveness of these materials is measured in Sabins.
The best sound-absorbing materials are open-celled foams, fibrous materials, and heavy fabrics like velvet and wool. These porous materials trap sound waves in tiny air pockets, losing energy and halting the sound.
Dense furnishings, like heavy velvet curtains, also help absorb sound. Their soft texture and folds create barriers that dissipate sound energy effectively.
Our speakers utilise innovative Metamaterial Absorption Technology to absorb unwanted sounds from the tweeter and midrange driver.

The Science Behind Acoustic Diffusion
If you’ve been wondering what diffusion is, it’s the art of reshaping how sound waves interact with surfaces to create a more even sound distribution. Imagine a disco ball scattering light. Audio diffusion works similarly, spreading sound waves evenly to prevent hotspots and echoes. With effective diffusion, sound travels smoothly around your room, guided along its path.
Absorption Vs Diffusion: Technical Differences And Applications
Materials: Deep, textured materials like dense foams and rich fabrics are best for absorption, silencing stray sounds. Diffusion panels, typically made from solid materials with intricate geometric patterns, scatter sound to ensure it spreads evenly across a room.
Frequency: Absorption is most effective at higher frequencies, while diffusion influences a broader range, depending on the shape and depth of the diffuser.

Applications
Many acoustic spaces require a mix of absorption and diffusion. Creating the ideal audio setup depends on the environment and specific needs.
Recording Studios
In recording studios, every sound should be precise. Speakers like LS50 Meta are complemented by foam-lined walls and bass traps to reduce echoes and clarify low frequencies. Diffusion panels maintain a lively sound.
Home Theatres
Your home cinema should provide immersive, balanced sound. Systems featuring Q Series deliver powerful audio. Absorption panels at reflective points ensure clear dialogue, while diffusers on rear and side walls create expansive surround sound.
Commercial Spaces
In busy environments, absorption reduces noise levels, facilitating conversation. Effective diffusion prevents sound clustering in hotspots.
Theatres
In theatres, diffusion scatters sound waves, creating an immersive experience. Orchestra pits often use diffusing panels to distribute sound evenly across the audience.

How To Measure And Address Acoustic Issues In Your Space
Start by identifying the issue: Are echoes and reverberations disrupting the space? Is excessive noise a problem? The human ear isn't always great at detecting specifics, but there are numerous tools available to assist you.
RT60 Measurement
An RT60 measurement indicates how long it takes for sound to drop by 60 dB, revealing a room's reverberation level. This helps optimise absorption and diffusion for ideal sound quality.
Subwoofer
Adding a high-performance subwoofer like KC62 can enhance bass response and overall sound quality.
Acoustic Materials
Acoustic panels, foam, or heavy curtains effectively absorb unwanted sound reflections.
Diffusers
Diffusers scatter sound across your space, improving sound quality when installed strategically.
Sound Meters
Sound meters measure decibel levels to identify sources of noise pollution. Simple DIY fixes, such as sealing gaps and repositioning furnishings, can significantly enhance your room's acoustics.
For complex spaces, a professional can assess your sound challenges and offer innovative solutions.
Whether you're designing a home cinema, recording studio, or commercial space, understanding your room's acoustic needs is essential for maximising the performance of your KEF HiFi speakers. By using the right materials and techniques, you can create a space where every note, whisper, or conversation is clear and captivating, providing an unparalleled audio experience.
