48 Pack 1.5in x 12in x 12in Egg Crate Acoustic Foam - Soundproofing

In this review the 48 Pack 1.5in x 12in x 12in Egg Crate Acoustic Foam is evaluated for home studios, rehearsal spaces and basic room treatment; the bottom line is that it is a budget-friendly way to reduce mid and high frequency reflections and make a room sound less live. The reviewer found the egg-crate geometry genuinely effective at increasing surface area and scattering sound compared with flat panels, and the included adhesive simplifies DIY installation, making it a practical choice for hobbyists and small project rooms seeking noticeable reduction in echo without professional installation.

Key Features

• Egg-crate shape: The undulating surface increases surface area to improve reflection scattering and friction inside the foam for better sound absorption than flat sheets.
• Strong adhesive: Panels arrive with adhesive backing to allow straightforward DIY placement on walls and doors without extra glue for many surfaces.
• Fire resistant: The material passed California Technical Bulletin 117-2013, offering added safety for indoor use.
• Non-toxic polyurethane: The foam is formulated to be non-toxin for safer in-room use compared with untreated materials.
• Vacuum-sealed packaging: Panels ship compressed to reduce package size and regain shape after airing in a ventilated room.
• Universal manual and support: A general installation manual is included and the brand offers direct customer service for setup questions.

Who It's For

The foam is well suited to musicians, podcasters and hobby studio builders who need an inexpensive, quick way to tame reflections on walls and doors and who prioritise easy DIY installation. It is also appropriate for classroom or home office setups where fire resistance and non-toxic materials are important.

Those requiring professional-grade isolation, deep bass trapping, or thicker industrial acoustic panels should look elsewhere; the pack is thin compared with professional absorbers and performs best on mid and high frequency absorption rather than low-frequency soundproofing.

Pros & Cons

Pros

• Effective egg-crate geometry improves surface area and helps reduce echoes in treated rooms.
• Adhesive backing makes installation quick and accessible for DIYers.
• Fire resistance and non-toxic polyurethane provide safer indoor use.
• Vacuum-sealed packaging keeps shipping efficient and panels recover shape after airing.

Cons

• Some users report the adhesive can be weak on certain surfaces, requiring extra tape or glue for long-term hold.
• Panel thickness is modest and may be less than a finger thick, so low-frequency absorption is limited.

Our Verdict

The 48 pack egg-crate acoustic foam is a sensible value option for anyone looking to reduce mid and high frequency reflections in a home studio or small room; it is cheap, easy to install with adhesive backing and safer for indoor use thanks to fire resistance. Buyers who need deep bass control or guaranteed long-term adhesion on difficult surfaces should plan on additional mounting materials or thicker professional absorbers.

Frequently Asked Questions

Will the panels stick to painted drywall?
The adhesive works on many painted walls but may be weak on some finishes; customers often add double-sided tape or contact adhesive for a firmer hold.

How long until vacuum-sealed panels regain shape?
Allow panels to sit in a well-ventilated room after unsealing and they typically expand back to shape within hours to a day.

Do these panels reduce bass?
They reduce mid and high frequency reflections effectively but are thin, so expect limited low-frequency absorption compared with thicker bass traps.
