Sonora® LFC – Low-Frequency Control Panel

Bass frequencies are difficult to control… and there is sometimes a tendency to overuse standard, broadband panels to try to absorb everything in order to get rid of that bass. However, this method is unbalanced and has the side-effect of leaving a room sounding muffled and boomy.

Why?

Physics! High frequencies are easier to absorb than low frequencies. So, when you ONLY use broadband absorbers, they easily remove the high frequencies and leave more of the lows. Overusing broadband absorption in a large performance space can be a disaster – leaving an environment lacking energy and feel – many describe this condition as a room sounding “dead.” (Not good!)

So how can you treat the boomy bass without killing your rooms with too much broadband absorption? Can you just take out the bass? Unfortunately, it is impossible to ONLY absorb the bass, but we can LIMIT the amount of high frequency energy that we absorb to balance out the response.

Acoustics First® presents… the Sonora® LFC – Low-Frequency control panel.

Looks like a standard Sonora® panel on the outside, but it’s completely different under that fabric!

The Sonora® LFC looks like a standard Sonora® Wall panel, but looks can be deceiving! At 4-1/8″ thick, it is virtually indistinguishable from a High-Impact Sonora® panel – however the interior structure of the LFC is optimized to attack the bass frequencies and smoothly roll off the high frequencies. Let’s take a closer look at the performance difference between the Sonora® LFC and the standard Sonora® panel.

Standard Sonora® 4″ Panel in red vs. the Sonora® LFC in blue.

When you look at the performance charts, you will notice that the standard 4″ Sonora® panel starts to “roll-off” in the lower frequencies below 125 Hz – it still absorbs them, just to a lesser degree. We designed the Sonora® LFC panel to focus on those frequencies below 125 Hz – while allowing the other treatments to handle the rest! This allows you to use fewer broadband panels, and still have some high-frequency energy for diffusers to spread around – thus creating a more balanced acoustic environment.

The Sonora® LFC is an engineered solution using the same high-performance materials as our other products, but combining them in a way that optimizes them for Low-Frequency Control – hence Sonora® LFC! The magic is in the way those materials are used.

The optimized construction of the Sonora® LFC Panel!

All of the materials used in an acoustic environment have a function – “Diffusers,” “Absorbers,” and “Bass Traps” are all general descriptors of product functions. Some diffusers are also Bass Traps. Some bass traps are also broadband absorbers. Some diffusers use absorption for amplitude grating. By combining a dampened, resonant trap with multi-density fiberglass, the Sonora® LFC focuses on making acoustic spaces more balanced. For controlling the bass without sucking the life out of a room, the LFC Panel is an outstanding tool for refined Low-Frequency Control!

The HiPer® Panel and Ken Fritz’s Dream

Ken Fritz completes his dream theater, and behind the scenes is the HiPer® Panel by Acoustics First®

There are many home theaters of note, but rarely is one created (at this scale) by the singular dream and dedication of one man. Ken Fritz involved Acoustics First® early in the project to perform acoustic measurements of the space, and his theater became the first large-scale installation of our newly developed HiPer® Panel. From beginning to end, Ken says that he spent more than 25 years on the realization of his dream – and others have taken notice.

Ken’s vision had a scale that is rarely seen in home theaters.

There have been numerous write-ups of Ken’s theater, which was constructed (from the ground up) specifically for this purpose. The walls are hurricane grade block construction, the roof-line is constructed to improve the acoustics, the walls are clad in HiPer® Panels, the bass emanates effortlessly from in-wall enclosures – and just look at those custom built arrays that Ken designed and constructed by hand! This project is more than just a labor of love, it is an obsession with excellence.

Even a custom-designed and hand-built turntable feeds Ken’s dream environment.

This obsession covers every aspect of the room and the system, with everything being either built by hand, customized to his specifications, or simply the best you can get! If there is a “home theater mountain,” Ken built a skyscraper at the summit – but don’t take our word for it…

You can watch the one-hour documentary telling the story behind the dream – in Ken’s own words.

Watch the documentary of what has been called “The Best Stereo System in the World.”

ASA 2020 – Acoustics Virtually Everywhere

AVE2020 Lobby

ASA Acoustics Virtually Everywhere Meeting 2020.

December 7-11, 2020: The Acoustical Society of America (ASA) is running their first fully-virtual meeting, Acoustics Virtually Everywhere (AVE).  The format is just like a real-life convention with a few interesting twists.  If you’ve ever had a scheduling conflict and needed to choose one presentation over another – you don’t necessarily have to!  Many of the sessions are prerecorded, so you can watch the presentations when you have time, and if you have questions you can reach out before, during, or after their allotted time!

There will be poster sessions where you can meet the presenters, and there are chat and social platforms for networking as well! Jim DeGrandis from Acoustics First® will be in attendance.

So… if you are an ASA member and were wondering about how this virtual meeting is going to work… check out the “Acoustics Virtually Everywhere” overview here
https://acousticalsociety.org/overview-ave/

If you aren’t an ASA member, you can find out more about the benefits of becoming a member here.

We look forward to seeing you there… Virtually.

3 Years of the Aeolian® Sound Diffuser

3 Years of the Aeolian®

It may seem a lifetime ago, but we are celebrating the 3rd Anniversary of the release of the patented Aeolian® Sound diffuser.  During development, our team ran numerous models and simulations, revising the design, and optimizing the performance to create the iteration we have today.

The development workflow of the design included computer optimized geometry, performance simulation, rapid prototyping, and full acoustic performance and validation testing.  This was one of the first uses of this completed workflow, and while we are always refining our development processes, this was a huge leap forward.

We now look back at the release of the Aeolian® as a milestone in our history, where we developed something more than a product… we developed a better way to design a product.

Here was the original blog post about the Aeolian®.

Happy birthday.

Acoustics First talks Diffusion in Sound & Communications

Sound & Communications February 2020

When Sound & Communications needed some industry perspective on diffusion, they decided to go to the source.  Acoustics First has been developing sound diffusers for decades, and has done some of the most comprehensive research on developing testing standards for diffusion and reflected acoustic energy with the ASTM.

Acoustics First’s chief science officer, Jim DeGrandis, covers why diffusion is so much more complex than absorption in the February 2020 edition of Sound & Communications.

Acoustics First would like to remind everyone that it’s the little things that matter…
…remember to wash your hands and stay safe.
