POLYFON BT
Bass Trap Acoustic Panel
LOW FREQUENCY ABSORPTION
& DIFFUSION PROPERTIES
POLYFON-BT is an innovative broadband acoustic
Bass Trap panel that combines Sound Absorption &
Diffusion characteristics.
POLYFON-BT Base, is polyurethane, flexible foam, corner type panel, with a
sculpted design, that effectively absorbs the sound energy and reduces the
reverberation time.
The addition of cavities (like Helmholtz resonators) offers maximum sound
absorption efficiency. Foam triangular-shaped bass traps POLYFON-BT, are a
cost effective solution for a reliable sound absorption. It can be installed into room
corners and/or wall or ceiling junction, to provide significant low frequency sound
absorption.
The acoustic energy is dissipated as heat in the foam cells.
Utilizing the depth of the corner, with foam material of some significant thickness,
is more effective also in mid and low (bass) absorption frequencies, than the flat
mounted acoustic foam which rarely has the thickness of BT.
Dimensions: 600 (H) x 210 x 460 mm
Color: Dark grey.
Packing: Box of 2 pieces.
Reaction to fire: SE according to FMVSS302.
The Diffuser Membrane (DM) is a flexible membrane, with a smooth radius,
which creates a 2D deflector that effectively spreads high frequency reflections.
Additionally, the DM improves the low frequency absorption coefficient; it acts as a
sound absorption membrane. The DM element can be either acrylic, plywood, HPL
“formica” or others radius membranes.
It can be easily removed from the two lateral channels, which keep the membrane
in tension.
