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.

Lessons from 2020 – Acoustics and More.

International Year of Sound opening ceremony in Paris… Pre-COVID-19 restrictions.

On January 31, 2020, the International Year of Sound held its opening ceremony at Sorbonne University in Paris – where there was much optimism for the education and advancement in the understanding of sound and how it affects our daily lives.  COVID-19 was just starting to enter into the world vocabulary, and we all met with no masks, no social distancing, and no restrictions (France had only just identified a few cases that very week.)  Little did we know how the year would eventually evolve.  Lock downs, Zoom meetings, working-from-home, and the virtualization of our interactions brought to light some issues that many of us had taken for granted.

Our personal spaces have become full of sound, with adults working and doing virtual meetings, while the children are taking classes from home.  The dogs are barking, the toddlers are toddling, the neighbors are jamming, and we are all becoming keenly aware of our acoustic environments.  This is a situation that we didn’t know we were going to be facing at that opening ceremony in Paris.  Some people never considered having to work from home, much less having a home office and having to work from home daily.  Even if you had a home office, did you really consider what it looked like… or sounded like?

Adding Sonora® Panels improves acoustics and creates an interesting backdrop for those Zoom meetings.

This melding of personal space and workspace has created some conflicts.  When you want a quiet space to work, you may be competing with your child’s virtual gym class in the other room, or your neighbor upstairs trying their best to stay active while the lock down has closed the gym – but these aren’t the only issues.  Maybe earbuds hurt your ears, or you are using the microphone on your webcam and people keep complaining about how it’s hard to understand you.  Speech intelligibility declines in poor acoustic environments and the acoustics of your home office may now have become an issue to others… not just if you understand them – but if they can understand you.

Adding diffusers to make it sound more like a home theater.

And it’s not just work and school… we are spending much more time in our homes this year.  People are realizing that their TV’s are becoming home theaters, and the room maybe doesn’t sound that good.  We are asking more of our home environments – we are asking them to be our offices, gyms, theaters, workshops, studios, as well as where we eat and sleep.  Many are making improvements to their homes to block sounds from their offices, improve the sound within the home office, make a better sounding TV room, and acoustically treating the kids’ rooms – to hopefully improve sanity for everyone.

However, not everything is so easily solved.  If you are in a multi-family dwelling, your neighbors may have different schedules than you. They may be night-shift tech-support, or sales for a different time-zone, or work for an international company.  Maybe their home office is directly adjacent to your bedroom, or your home theater is causing them problems.  Some have learned to adapt with sound masking solutions, acoustic treatments, or improvising their own home-grown solutions to address sound problems.

So, 2020 has not been the year we thought it would be in January.  We have had to learn to compromise in the face of adversity to improve this situation for everyone – and it’s more than just making our home sound better for work or leisure.  This goes beyond our own walls, and our own ears.  Improving acoustics helps our neighbors work and their children learn.  We are helping our co-workers and our customers. We are making the best of a difficult situation – while looking to the future with hope and optimism.

Here we sit at the end of 2020… and the International Year of Sound has been extended into 2021. We have learned many lessons, and have had to solve problems we never thought we would have to face.  The world sounds very different now – we have found new ways to experience entertainment, new ways to work, new ways to play, and new ways to socialize.

Moving forward, we will need to integrate these solutions into our future reality.  The Year of Sound has taught us lessons through adversity that we would have never learned otherwise – and those lessons of hope, optimism, tolerance, ingenuity, and compromise will serve us well as we face whatever the future holds.

Setting the Soundstage: How to treat your home theater like a real theater

Modern AVR’s include all kinds of wizardry for speaker setup, positioning and room equalization. Anyone in the know will tell you that room EQ hardware and software should be a last resort. Correct acoustical treatments will pay much bigger dividends.

If you are like many people, you have recently upgraded your home theater, or you’re getting ready to do so.  During this process you’ve likely learned that the speakers in the TV are sub-par and you should upgrade your audio experience to include an external sound system.  This has become common practice and common knowledge. What you haven’t learned, and which is probably even more important, is how to upgrade the room itself.

One of the things people overlook when trying to make a home theater, is that a real theater pays a lot of attention to the design and treatment of the theater environment. They have good left-right design symmetry (see the diagram for a sample home theater layout).  A good theater also has acoustically treated the space so that people can hear everything that is happening, from anywhere in the theater.  This article will teach you some of the tricks of getting that great big theater soundstage into your home theater.

Bass Traps – the low-down solution.

Low frequency problems are common to almost any room, regardless of size.  The good news is that, most of the time, the solution is simple: put bass traps in the corners of the room.  This is one place where it pays to put a little extra in the budget.  Corners are defined as the intersection of two or more surfaces. There are not just corners at the end of each wall, but also along the floor and ceiling where the walls intersect them.  The more corner you cover with a good trap, the better bass response you get – it’s that simple.  Bass loves the corners, and by putting bass traps there, you keep the bass crisp and natural.  If bass frequencies are allowed to build in the corners, it causes the bass frequencies to become muddy and undefined – trap them.

Some bass traps work double duty as broadband absorbers as well, which can keep your costs down when considering covering a bunch of square footage with absorbers. Bass traps alone can solve many problems in your room, and due to the simplicity of the implementation, I recommend you start with these first – at least fill the four main corners.

Foam works. But this is a theater, not a studio.  Fabric wrapped absorbers look as good as they sound, and Geometrix™ by Acoustics First, fit the corners like a glove.  Pick a fabric and get some quarter rounds to fill your corners – that’s it.

Broadband Absorption – tame the ring.

Another common problem in home environments can be easily verified with a clap test.  Go into your room and clap your hands.  Most likely you will hear more than just the initial clap.  Depending on the severity of the problem, you will hear a flutter, ring, or echo after the initial *pop*.  This is caused by the sound waves bouncing around off the hard surfaces of the room and returning to your ears after a delay – the more times they bounce without losing energy, the longer the delay. The best way to remove energy from these waves is to use broadband absorption, but where do you put them?

More than likely, your TV and sound system are going to be in a fixed position, and your listening position will also be fixed – so the early reflection surfaces should be easy to locate.  You will need a friend for this activity, a mirror, and a pencil. Have your friend place the mirror flat against the side wall and move it around until you can see the speakers in the reflection from your seat – then mark the wall. This is where you are going to place the absorber. The diagram shows a good place to start looking for these reflection paths. Repeat this for all the walls from all the seats. 

What you are looking to create is a reflection free zone, which basically means, wherever the sound could bounce off a surface and get to your ears, we are going to absorb energy from it.  You can spend a good deal of time on this, but this is the only step that requires this time and effort, so make it count.   Sound travels in all directions from the speaker, including behind it, so put absorbers behind it on the wall. Don’t forget the floors, ceiling, and the wall behind you – sound will bounce off those as well. 

This simple process will show you where you need to treat.  Hang broadband absorbers over all the early reflection points – left, right, front and back.  Absorber clouds should be hung on the ceiling, and place a nice thick carpet on the floor.  Placement is the first key to getting this reflection free zone.  The second is the right choice of absorber

To match your fabric wrapped bass traps, the simple choice is get some more panels wrapped in fabric. The Sonora® line of broadband absorbing panels coordinate with the bass traps, and come in a plethora of sizes and mounting options to work in your space.  Need 2’x4’ behind the speakers, 4’x4’ on the sidewalls, 2’x6’ on the back wall, and a 2’x6’ ceiling cloud – all in material that match those bass traps? Done.   

Finally, use broadband absorption with caution, specifically using too much.  If you plan on covering more than 50% of your walls with this stuff, you’re going to notice a muffled almost claustrophobia inducing deadness.  We are not trying to suck the life out of the room.  We are just trying to take enough energy away from those early reflections to keep the focus on the initial sound produced by the speakers.

Diffusers – put life back into your space.

The steps we have taken up to this point have been using absorption to control excess energy that can have an adverse effect on the listening environment.  We have removed the unwanted direct reflections and we have tamed the bass, but there is something more we can do to give life to this room – diffusion.

Diffusion will give us something we couldn’t attain through absorption – a sense of open space.  Even after treating with absorbers, there are still areas of the room where sound waves will sit, because your room is a fixed box with fixed speakers.  Diffusers scatter the energy, creating ambiance with residual energy, like sitting quietly in a forest – the energy around you being directionless, omni-present, and spacious.  This simple step does not remove energy from your room, but redistributes it into a soundscape that can make you forget you are in a room at all.

There are many ways to diffuse the sound and coordinate with your room, from the fabric covered HiPer™ Panel and Double Duty Diffusers™, to the striking line of Art Diffusors® like the Model C, which can be painted to match your décor. 

Advances in acoustic treatments are being made all the time, bridging form with function, creating products as visually stunning as they sound – and helping your theater, or any theater, be the best that it can be. So use these tips to set up your home theater like a real theater, and experience the difference a soundstage upgrade makes.
