THE REVERB PROBLEM.
One of the most important problems during the reproducing of the musical message is the reverb.
For example, in rooms not completely furnished or with a big glass surfaces, the sound wave is almost completely reflected, causing unpleasant effects and being annoying.
The absorption coefficient is the parameter that defines the amount of energy absorbed by a material when struck by a sound wave.
When the absorption coefficient is equal to 1, the sound wave is completely absorbed, when it is equal to 0 the sound wave is completely reflected.
The absorption coefficients change depending on the material of the surface and from the energy of the sound wave that strikes it, then from its frequency.
POSSIBLE SOLUTIONS
To solve these problems exists different solutions, some extremely expensive.
Use sound absorber pictures is a simply and cheap solution.
At the end of this page you can find a brief guide on the positioning of the panels.
This guide will not be the final solution to your problems, but want to be only a little help for the correct positioning of the sound absorber pictures, considering some example of rooms usually dedicated to the listen of the music.
Usually a room furnished with carpets, bookshelves and curtains, requires fewer Armonia pictures.
A big size room not completely furnished and with a big glass surfaces, required more Armonia pictures.
TECHNICAL SPECIFICATIONS
The Armonia sound absorber pictures consist in a MDF frame 50 mm (2”) thick. The result is a product very light and handy but strong and durable.
Ax you can see from the curve absorption graph, the Armonia pictures are effective from 250 Hz and they reach maximum effectiveness between 500 and 4000 Hz.
The sound absorber panel used in Armonia pictures is made of polyester fiber and therefore is fireproof Class 1 (one) and F1 fumes class.
