Sound diffusion is the final piece in the jigsaw puzzle of acoustic treatment that, when used coherently, is capable of transforming the good acoustics of a room into excellent acoustics, therefore providing the sound setting with a sense of spatiality via the dispersion of undesired reflections and the breaking of floating echoes, free of additional absorption.
KONTUR is a one-dimensional sound diffuser based on a QRD (Quadratic Residue Diffuser) mathematical sequence that has been innovatively optimised to reduce the comb filter phenomenon that often occurs in diffusers designed with periodic mathematical sequences, therefore achieving an exclusive diffuser with an excellent level of sound dispersion in the range of frequencies between 630 Hz and 8 kHz.
It is manufactured in high-density EPS, which makes the diffuser extremely light and enables it to be easily installed on walls and ceilings using a neutral assembly adhesive (Skac Adhesive) at a contained cost which, along with its performance, make this device an unrivalled sound diffuser.
The material of a KONTUR diffuser means it may be painted (using water-based paints only) without affecting its diffusion performance.
Its quadratic design means it can be turned 90º to achieve sound dispersion along multiples axes. The combination of diverse units, alternating their orientation, enables the achievement of a two-dimensional set with optimal incident sound diffusion in all directions of the space.
KONTUR sound diffusers are specifically recommended for providing spatial and temporal sound diffusion to the sound setting of control rooms, recording rooms and mastering studios.
Used in a control room, the monitors will present a more precise and more expansive setting, and by placing them in specific positions they will break the floating echo (or undesired reflections).
In a recording room, sound will return more naturally and with greater definition, without losing the energy common in rooms with excess high-frequency sound absorption.
KONTUR sound diffusers have been designed to offer one-dimensional dispersion, which is beneficial with regards to two-dimensional diffusers, which disperse energy in two planes, especially in the design of control rooms.
To obtain maximum dispersion performance throughout the range of frequencies used by the sound diffuser it is recommended a minimum distance of 1.3 m from the diffuser and the listener is maintained.
KKONTUR diffusers were designed as modules that may be installed continuously, creating greater length. To maximise their performance and avoid the comb filter effect use the following sequences:
