Must read writers

Are you interested in reading or watching inspiring views, new insights, different takes on what enterprise, humans and the world can be?

Among others, these 3 dudes indeed are inspiring. And while I believe they, Gunther Pauli, Simon Sinek & Alexandre Gerard, should be universally famous already, I keep on bumping on people who truly are awed to hear about them and alleviated that their actions are for real, hence my post of this week.

The future is happening now and what these writers do, invent or implement is just great and exciting!

Code / Poésie – Digital lyric

Château de Morges, now, until May 10

What are you doing for the future?

Rainer Maria Rilke, Charles Pennequin, Darth Vader embrace modernity and these fascinating characters indulge in the beauty of computer art, virtual reality, immersive sound, until early May in the historic setting of the Château de Morges.

Do you want to contemplate a today where history and the future reach out to discover magnified poetry via playful, creative and digital installations? The secular museum hosts a fascinating exhibition where our cultural heritage is transcended by the most innovative sound and visual museography!

Peaceful immersive sound year

Our universe is bathed in a thousand sounds, sometimes nice, sometimes disturbing.

We invite you to dive in the experimental and immersive four-minute video that we have created for you, with DomB, for the images. Connect your headphones and have fun wandering around in the 360° audio and visual space …

From 2’20” on, you will discover a binaural sound which induces a feeling of relaxation. With 6 Hz, Theta waves.

We wish you a sound universe where peace reigns. Daily.

Thanks, Pierre André Aebischer

Easy absorption

Room acoustics absorption is rather easy. Allocate the equivalent of about one third of the floor surface of  your space for absorbing material, thick and soft. Put that up in plain sight anywhere that may be convenient for you. My example of choice is rockwool 50 mm thick. Similarly specced materials exist in the form of ceiling panels, printed artwork or open space furnitures.

Now that the first issue has been taken care of, the conversations, even remote ones, become more noticeable. This has to be addressed. One option is the use of panels or furnitures, thick, soft, high and numerous enough to split the space into smaller zones, thus disabling most of the direct sound transmission.

Would you like us to meet ?

NB 1: if you are not ready to solve the above problems above head-on, I suggest that you do not bother at all, because, while insufficient absorption can first give the illusion of effectiveness, no real measurable comfort can be obtained unless the issues are adequately addressed.

NB 2: Isolation between volumes/floors/room/apartments, on the other hand, is very delicate and a professional acoustical engineer should be called in asap. Once it is built wrong there is not much you can do about it, besides not renting the place at all, or flooring the whole thing and starting up from scratch with an entirely new building.


Why move to multi-channel immersive audio?

Because anything is possible, now. A bit like in the 60’s when the Beatles and the Stones were inventing show-business and stereo. Likewise, today all multichannel audio / immersive / spatialized / SuperDiff can be questioned, experimented, created. I love this moment. Even naming and best practice conventions still are evolving, but it exists! Big time. To name a few: Youtube, Facebook, Sony, L-Acoustics or Meyer have working systems, along with us @ PAA-Consulting. So, already multi-channel immersive audio is available for live shows as well as for your living room. For headsets, museum, art-galleries & for huge open air events too.

Artists, time to reclaim your creative edge!

In the 1980s, the number of audio channels swelled exponentially. From the “modest” tracks count of the sixties where four or eight were enough to create the firsts Rolling Stones or Beatles albums, it flourished in biblical proportions to 96-channel SSL or Neve consoles attached to two Dash 48 tracks digital recorders, de-facto standard in 1985 & the size of rather large refrigerators. With matching leasing contracts.

Everything was cool and the 80’s were great years for studios: besides the crew of a modern liner that was needed to operate all these equipments and the serious studio time that was consumed to fill up the 96 tracks. But I think something got lost on the way, something about the pleasure of recording, playing together, spontaneity…

I never imagined saying that one day, but thank you Facebook and Google: today’s audio/video 360° allows artists to be at the center of their creation again. This is true for the image, for the sound too. In essence, the explosion of the traditional video framework and the stereo audio format, effectively gives the artists extensive creative possibilities. It’s up to them to decide what they want to do with these…

Yes, size matters! Ask the Rolling Stones!

For music, tempi, beats, at least. It is as if the very place where the music is played was, is, part of the music itself, just like one extra big instrument being part of the band.

Interestingly, there is an absolute critical size, for rooms, around  the 100 m2 range where sound start to react completely differently. This paradigm shifting dimension interact with how the music can be played and/or perceived in a said room. Smaller that that size, you are perfectly free to play at any tempo you fancy, but, you are stuck with notes or scales sounding better than others. Bigger than 100 m2 and it is exactly the opposite: you are welcome to play in any key your fancy, but the room dictates what works and what doesn’t in terms of tempo. Ask the Rolling Stones.

Be nice to kids! Acoustically !

Class rooms are school equivalents of open spaces, at best. Recently I have been introduced to a conferencing solution reshuffled voice lift for class rooms. With the USP being that student in the back of the classes would actually be able to understand things that were said by the teacher. Great this is called a PA, this is what I do. I am happy to design such systems for any school in the known world… Just a tiny little detail here: is it always the appropriate solution?

Why not start with good room acoustics first then? This has been pretty well documented so far: about half of the pupils in most of the classrooms today can’t really understand a word of what is being said by the teacher, because of poor room acoustics. So, why would you pile up kids in classrooms for most of their best days of childhood, ask them to remain quiet and attentive AND get them to do so in an acoustically challenging environment for about half of them.

Do you think simple, elegant &  affordable solutions exist?

Adequate acoustic treatment, a profitable investment for your open space?

Questions, phones, emails, notifications, pop-ups, messages, 6 different potentialities to be interrupted daily. At 20 minutes on average for a return to concentration, two hours lost.

In open space, add a minimum of 6 interruptions generated by unrelated noises, 2 more useless hours, a total of 4 hours of productivity per day soaring. These figures are freely accessible, please check for yourself.
