Benefits

With the Walldamp Iso-Wall System, you get walls & ceilings that reduce sound transmission by 20dB or greater compared to standard interior walls. That is more than quadruple the perceived sound volume reduction, which is what makes our wall system the highest available using standard single-stud construction. Internally, the walls are tempered to move with the air pressure of bass frequencies. Where a rigid wall would shudder at high volumes (similar to the distortion in an overdriven speaker) and raise the noise floor of the room considerably, an IsoWall will "bend" with the pressure and absorb the sub bass sound wave while allowing the bass waves to reverberate cleanly. 

What is Room Break Up?

In nature, most things tend to stand still and, if they are disturbed, they tend to regain their rest condition quickly.  This is how the familiar world is put together. At low sound levels, the walls and other surfaces of the room are able to dissipate the sonic power without moving, by conducting sound into the rest of the house.  But, inject high power audio into a normal room and something new happens; the surfaces of the room become fluidized.  They act like the surface of a bowl of jello. 

At high volumes, more power is being delivered to the walls than they can conduct away and thus begin to move.  Moving walls radiate sound just like the moving diaphragm of a loud speaker.  Moving walls radiate much more power than they do while standing still and conducting sound away.  Although a new level of energy flow has been achieved, when the music stops, the moving walls maintain their motion.  They are filled with stored up energy and continue to shake (mechanical reverberation) until they have broadcast the energy away and gotten rid of their stored energy.  It is true that half the sound from the wall, the outside half, is broadcast away from the listen room into the rest of the house.  But, the other half, the inside half, is broadcast back into the listening room, where it will be heard again and again and again.  

A room with a steady noise floor, due to air conditioning, noise lacks dynamic range.  It’s like a projection video screen being in a room with some lights left on.  Wherever the light hits the screen and grays out the black, the dynamic range of contrast is reduced.  A room with a self made noise floor, due to some reverberation, also lacks dynamic range.  It’s like a projection screen in a room that has lots of white surfaces.  Light from the screen reflects off the surfaces and back scatters onto the screen, illuminates the black, turning it to gray and reducing the dynamic range of contrast.       

How to Fix Room Break Up

The IsoWall System adds a damping feature to the room.  When the walls start to move, the damping feature begins to absorb the energy out of the movement.  If the proper amount of damping is added, the walls remain flexible but never can be driven into free vibration.  The more they are bent under the pressure of sound, the more energy they absorb.  The walls become self stabilizing and energy absorbing.  Since the damping feature absorbs the energy of wall movement, the wall gets rid of its energy without broadcasting it throughout the rest of the house or back into the listening room. 

Adding a damping feature to the walls and ceiling, doors and windows of your high power audio room lets you not only break your old sound level barrier, but completely eliminate it from your room.  Now you can enjoy high performance playback with unlimited sound levels, like a professional recording studio.
