|| Sound-Engineered Floors
What are sound-engineered floors?
Sound engineered floors are also known as "soundproofed"
floors, and are floors designed to limit the amount of airborne
noise in a structure. Sound engineered floors can be used in conjunction
with sound engineered walls and ceilings to reduce the amount of
noise that travels from room to room within a structure. Sound engineered
floors are often used in multi-family residential structures like
apartments and townhouses where sound traveling through the floors
is a problem.
How do sound engineered floors work?
Sound engineered floors reduce airborne noise by absorbing the sound
waves through the addition of layers of varying density and disconnection
points to the floor surface, a process called "damping."
Since sound travels through vibration, the addition of layers and
disconnection points to the floor surfaces limits the ability of
the sound wave to vibrate to the other side of the floor and become
audible sound, thereby reducing the level of airborne noise.
Adding insulation using mass-loaded vinyl
The most common way of soundproofing floors is to insulate the floor,
or add a layer in between the bottom of the floor and the visible
floor surface. To that end, mass-loaded vinyl is often used to soundproof
floors. Mass-loaded vinyl can be installed on top of existing hard
floor surfaces, such as hardwood, linoleum, or tile. Once the mass-loaded
vinyl is added, a new hard floor surface is installed on top. Mass-loaded
vinyl can also be used in conjunction with carpeting. In this case,
the original carpeting, padding, and baseboard must be removed.
Once the carpet materials have been removed, the mass-loaded vinyl
should be stapled to the raw floor surface, or "sub-floor."
Finally, after the mass-loaded vinyl is securely installed over
the sub-floor, new padding and carpeting should be installed over
the vinyl, and the baseboard should be reinstalled.
