Restorative acoustic conditioning

Acoustical conditioning as a restorative factor

(A speech given to the local Toastmasters club members)

I open with a strong one-time clap of hands.

Did anyone hear an echo? No? Well, it was a very quick-responding one. Not a long-ringing echo, such as one can hear in a large room.

Large PRD-architecture

Math or no math, that’s the question

Architecture that – unintentionally – form large diffusers

PRD’s are diffusers based on math, on Prime Roots to be exact. The calculated surface irregularity ensures that soundwaves are treated much the same way as stealth planes deal with radar waves.

Walking through Helsinki city with a mind (heart) focused on acoustics, on how to dampen noise, inevitably a structure will catch the eye. A structure that reminds of a sound-treating construction.

Long time, no blog…

I haven’t sat down to post a blog in a long time. All summer, actually. I suppose that is a good thing. What if no-one has the time to read blogs in the summer, everyone being busy.

Came home today with a Marimekko purchase. My wife, seeing only the paper bag, emotionally commented in the lines of “what have you spent money on, you know we can not afford…”. It took me a second or two of my own silence to figure out that she did not know what was in the bag.

For about 6 months, I have known that this piece of acoustic panel – with this particular  textile art – is something I really want to make. Partly because it is one of the few ideas of mine that my wife early on accepted to decorate our living-room. And partly because it (Räsymatto – rag rug) is one of my favorite patterns, showcasing a sense of harmony.

Every time one of my acoustic projects crosses the finish line, I feel a certain satisfaction. Although a project did not turn out fully to my expectation, it is still a milestone in learning. And, not least, satisfaction arises from the fact that I am 1 step forward in program of planned releases.

However, the best satisfaction with this project here is that it turned out very well. IMHO. It is time that it did turn out well; it has been a long road with quite a number of pilot projects..

Every project demands a bit of preparation work… and coffee 🙂

About the author

Martin R.C. Andersson started out as a mechanical engineer, slowly developing a soft spot for project management in which he worked 10 years.
Although having resigned from a corporate career within project management, the soft spot he keeps alive through a keen interest in room environment treatment. By control of sound and light, looking to tweak for that noise-free listening… which should be a norm.
Values silence, and now and then solitude.
Thinks Mindfulness is a ‘state of being’ when work really gets done.
When thoughts flow – without disruption – to reach either a creative state or finish what’s at hand.

When the outside world is tuned out, performance is tuned in.
Feels best when Minimalism, Functionalism and Art come together, crossing their paths.

Light- and soundscape

The light- and soundscape in our lives

There are several doctoral studies made, and study disciplines, into the psychological world of how light and sound affects us. Indoors and outdoors. How these have effect on our mood, well-being, behavior and performance. Performance, as in creativeness,  endurance at work or in studies.

One very interesting area within these studies is Restoration – how well and soon we bounce back from fatigue. Restoration can be measured. How to measure, is in itself a huge field of study. How to go about to standardize measurements with sufficiently acceptable and reliable factors.

DESIDERATA – Harmony in silence

Mind your Ear(s)

A quest for a better sound experience, where a good start is to improve quality of sound by controlling echo.

And, to minimize the noise in your space. Be it in your home, office or a public place.

Where-ever your space, seek to better enjoy and make use of your environment.
