The Lyngdorf CS-2 is a unique compact full-range loudspeaker crafted meticulously to be placed discreetly within cabinets like lowboards and sideboards, as well as under TV furniture. Its design incorporates a front-ported bass reflex and a distinctively positioned elevated and angled tweeter. This clever positioning of the tweeter mitigates sound diffractions caused by furniture edges and optimizes sound distribution toward the listener. Particularly, its design integrates smoothly with Clic audio/video furniture known for its elegant fabric doors, aligning functional acoustics with aesthetic considerations.

From a performance standpoint, the CS-2 utilizes the same midrange driver and tweeter as found in the CS-1 but comes in a slightly taller and less wide enclosure, effectively maintaining equivalent sound quality. The speaker leverages a powerfully built 6.5” midrange driver equipped with a robust magnet, supplemented by the front-ported bass reflex to enhance the bass response down to 42 Hz effectively eliminating the necessity for a subwoofer. The aluminum-made speaker cone contributes to its performance by being both lightweight and rigid, promoting a precise sound output with minimal distortion. Additionally, its textile soft dome tweeter assures clarity of sound and an expansive soundstage even when the speaker is embedded in furniture.

Built with durability and performance in mind, the CS-2 features a robust MDF construction finished in a sleek matte-black lacquer that not only adds to its visual appeal but also ensures its longevity and ease of maintenance. The speaker does not incorporate a front grille to prevent any dampening of sound quality, allowing it to perform optimally even when placed behind fabric-covered furniture doors. To protect furniture surfaces and minimize resonance, it comes with self-adhesive rubber pads. Furthermore, its dimensions are specifically tailored to fit seamlessly into Clic’s range of audio/video furniture, enhancing both utility and visual harmony.

Bose is preparing to unveil new open-ear clip-on headphones at CES 2024. The potential name is Bose Open Ear TWS. One of the key features is that the sound comes from outside the ear, so the headphones do not go inside the ear canal. For many people, this will be much more comfortable and will also allow them to better hear what is happening around them. Like other clip-on headphones, they will have a G-shaped design that clips over the ear. This trend is becoming popular among other manufacturers as well.

This is not entirely a new model, and in 2021, Bose experimented with headphones of this type. It is likely that the new headphones will simply be an improved version with refinements in design and technical specifications.

Preliminary information shows models in silver, but it is also possible that there will be black, and possibly other colors. So far, there are open questions about water resistance, active noise cancellation, and integration with smart devices.

More detailed information is expected during the official unveiling at the CES 2024 trade show.

#### Why Acoustic Terminology Matters

Understanding the language of acoustics is not just for scientists or sound engineers; it's essential for anyone passionate about achieving the best sound experience, whether you're an audiophile or a professional. Knowing terms like "Reverberation" or "Absorption" can help you diagnose problems in your listening room or even enhance your enjoyment of music or movies.

#### The Four Pillars

At the heart of acoustic understanding are four key terms: Reverberation, Absorption, Reflection, and Diffusion. Think of these as the four pillars that uphold the 'temple' of sound quality. Understanding these terms can significantly elevate your listening experience.

----------

### Unpacking Reverberation

#### What is Reverberation?

Reverberation is the continuation of sound in a particular space even after the original sound source has stopped. Imagine clapping your hands in an empty room; the sound lingers for a few moments, bouncing off the walls, ceiling, and floor. That lingering is reverberation. Too much of it can muddy sound quality, while too little can make a room feel "dead."

#### Reverberation Time (RT60)

RT60 is a metric that measures how long it takes for the sound to decay by 60 decibels in a room. In simple terms, it gauges how 'echoey' a room is. Measuring RT60 helps in tuning a room for optimal sound quality. For example, a home theater might aim for a shorter RT60 to keep dialogues crisp, while a concert hall might aim for a longer RT60 to enrich musical notes.

#### The Role of Reverberation in Different Environments

Reverberation behaves differently depending on where you are. In a recording studio, excessive reverberation is usually undesirable as it can muddle the clarity of recordings. Conversely, in a concert hall, a certain level of reverberation can add richness and warmth to live performances. Even in your living room, getting the reverberation right can make your hi-fi system shine.

----------

### The Absorption Factor

#### What is Sound Absorption?

Sound absorption refers to the process where materials, like acoustic foam or carpeting, "soak up" sound waves, reducing echo and background noise. Imagine sound absorption like a sponge soaking up water, but in this case, the sponge is soaking up sound energy.

#### Noise Reduction Coefficient (NRC)

The Noise Reduction Coefficient (NRC) is a number between 0 and 1 that indicates how well a material absorbs sound. A higher NRC means better absorption. For example, acoustic ceiling tiles with an NRC of 0.7 would absorb 70% of the sound hitting them, reflecting the remaining 30% back into the room.

#### Practical Applications of Absorption

In a home theater, strategic placement of absorbing materials can help reduce unwanted noise and echoes, making dialogues and musical scores clearer. In recording studios, absorption is essential for capturing the 'true' sound of an instrument or voice without interference from the room itself. Even in industrial settings, absorption can be crucial for employee comfort and safety, mitigating the impact of machine noise.

----------

### Understanding Reflection

#### The Basics of Sound Reflection

Sound reflection is the phenomenon where sound waves bounce off surfaces like walls, floors, and ceilings. Imagine throwing a ball at a wall; it comes back to you, right? Sound behaves similarly. When sound waves encounter a hard surface, they reflect back into the room. This can either be a positive or negative factor, depending on what you're aiming for acoustically.

#### First Reflection Points

First reflection points are the initial surfaces that sound waves hit after leaving a speaker. They're critical because these first reflections will reach the listener almost immediately after the direct sound, and can either clarify or muddy the sonic picture. In most cases, these are spots on your side walls, ceiling, or floor. Knowing where these points are can help you decide where to place absorbing or diffusive materials.

#### Reflective Surfaces and Sound Quality

Reflective surfaces aren't all bad; sometimes they're exactly what a room needs. For example, in a home theater, you might want some reflection off the side walls to make the audio sound more spacious. However, in a recording studio, excessive reflection could distort the true sound of an instrument or voice. The key is to find a balance between reflective and absorbent surfaces.

----------

### The Complexity of Diffusion

#### What is Sound Diffusion?

Diffusion is the scattering of sound waves in multiple directions. Unlike absorption or reflection, which deal with sound in a more linear way, diffusion disperses sound, reducing the sense of localization. Think of it like a garden sprinkler for sound; it scatters water (sound) uniformly in different directions.

#### Types of Diffusers

There are various types of diffusers, but two common ones are Quadratic Residue Diffusers (QRD) and Primitive Root Diffusers (PRD). QRDs use a sequence of well depths to scatter sound, while PRDs utilize a different mathematical formula for a more randomized scattering. Both have their strengths and weaknesses, but the goal is the same: to spread sound energy across a room evenly.

#### The Role of Diffusion in Room Acoustics

Diffusion can enhance a space by making it sound larger and more open. It helps break up sound energy and redistributes it throughout the room. This is beneficial in places like home theaters where you want a balanced, immersive sound field, or in music studios where you want to capture a more natural ambiance.

----------

### Putting it All Together

#### The Interplay Between the Four Terms

Understanding Reverberation, Absorption, Reflection, and Diffusion in isolation is good, but appreciating how they interact is even better. For instance, too much absorption can make a room sound lifeless, but adding diffusion can breathe life back into it. Likewise, too much reflection could cause problems, but the right amount of reverberation could fix it.

#### Case Studies

Real-world examples can illustrate how a blend of these four elements can create an acoustically optimized space. Whether it's a Grammy-winning recording studio or a state-of-the-art home theater, the principles remain the same: balance and harmony between these four pillars.

#### Final Thoughts and Further Resources

Mastering these terms is essential for anyone interested in acoustics, whether you're a professional or just passionate about sound. For those looking to deepen their knowledge, various books, online courses, and consultation services are available to guide you further.
