Key Features for Comparing Acoustic Foam Online

1. Key Features for Comparing
Acoustic Foam Online
When shopping for acoustic foam
online, the four
key features commonly compared

2. Thickness of Foam
• Acoustic panels
typically come in
thicknesses of either 2″
or 4″.
• 4” panels are
considered better and
will cost a little more
then their 2” counter
parts but will absorb a
more range of
frequencies.

3. Surface Pattern
• Most panels will have
some type of 3D-
pattern on their outer
surface, wedged
and pyramid being the
two most common.
• No single pattern is
better than the rest, so
feel free to chose one
that suits you.

4. Dimensions of the Foam
• Standard bundles normally
come in packages of 6, 12,
24.
• With these dimensions 1ft²,
2ft², 2ft×4ft.
• For a typical home studio,
where wall damage is a BIG
concern. I recommend using
smaller panels because they
are lighter, and can be
more-easily mounted using
non-permanent adhesives.

5. NRC Rating of the Foam
• Good sound absorbing
panels have a Noise
Reduction Coefficient
rating between 0 and 1.
• With 1 being maximum
and 0 being minimum.
• Purchase those foam
panels who have a NRC
rating closer to 1.
