Sound waves entering continually intrenally reflect and suffer propagation losses.
The Fibonacci Frequency Traps® (FFTs) are unique in their application of the Fibonacci curve in Acoustic Dampening which can be analogous to a simple 'sound black hole device'... that is once a sound wave enters the trap it travels inside the trap until it's energy is adsorbed and not reflected back to the source to cause interference or standing waves.
The internal surface of the FFTs will, at the point of contact with a sound wave reflect and adsorb at known rates that after a few bounces of the sound wave inside the FTTs will have adsorbed all of its energy or the wave. If the incident angle becomes perpendicular to the surface then the maximum energy is adsorbed on collision. If a portion of the reflected sound travels back along the path it took coming into the FFTs then the absorbance properties will deplete it's residual energy.
The Fibonacci curve is used to provide a multi surface effect (owing to incident and reflection angles) which will all resolve the sound waves path to end with a perpendicular adsorption. Therefore rather than having multiple bulky sound adsorbing panels placed in different locations... one simple Fibonacci surface will provide the multiple sites of adsorption as in the Fibonacci Frequency Traps®.
Sound is particle vibration wave where the movement of particles are parallel to the direction of propagation of the wave, when sound (particle) energy passes over a fibrous acoustic material the energy is absorbed and converted to kinetic energy. The more fibrous a material, the better the absorption of sound.
The Fibonacci Frequency Traps® achieve "More" by its use of the Fibonacci curve to internally reflect 'more' and provide 'more' sites of adsorption along the reflections path. If the energy is not sufficiently removed on the first reelection.... subsequent ones will adsorb the residual particle energy.
The Fibonacci Frequency Traps® can used in smaller spaces with their various configurations.
The Fibonacci Frequency Traps® are lightweight and can be placed into overactive areas in a studio to disrupt standing waves and reflections. Recording acoustics and Mastering acoustics are different and can be quickly reconfigured by having mobile traps which can be freestanding, be laid down or hung up.
The absorption coefficient (Sabin) of a material is a number between 0 and 1 which indicates the proportion of sound which is absorbed by the surface compared to the proportion which is reflected back to the room. FFT's keep reflections internal.
