If you’re soundproofing a room and thinking about getting a sheet of memory foam for the job, think again. Even though the material is comfortable to sleep on, it’s usually not as dense as soundproof foam.
Mattress foam is designed differently than soundproofing foam. Despite offering some soundproofing and preventing distortion, the foam mattress is not the best material and prevent sound traveling.
Can Regular Foam Be Used For Soundproofing?
Does memory foam absorb sound? No, It’s useless as a soundproofing material. You may think your foam mattress is pretty dense and would stop a bullet, but the truth is it’s not dense enough to stop sound.
Soundproofing is specialized, and the materials used are specifically designed to stop specific frequencies. Your mattress was designed for comfortable sleep.
However, sometimes there are budget restrictions that force us to be creative, so why not try and see if mattress foam is suitable for soundproofing.
If you manage to line your audio studio with mattress foam, you will be confronted that the mattress foam only stops distortion and reverberation at a particular frequency.
So, if you are singing, the lower notes will not be affected by the mattress soundproofing, while the higher notes and tones will be muffled.
Soundproofing is all about density and some other complicated factors.
What Kind of Foam is Best For Soundproofing?
If you are looking for a professional quality soundproofing job, then you need acoustic foam. But the story doesn’t stop there.
For the acoustic foam to achieve the desired results, the foam comes in various shapes and designs for sound absorption and sound reflection of specific sound waves.
The most common soundproofing foam is acoustic wedge foam. It is reasonably priced and covers a multitude of aspects of sound waves.
Once you move away from wedge foam, the price increases and your soundproofing project can become incredibly expensive.
Let’s face it; soundproofing is a science, and we get limited results using foam mattresses as a substitute for acoustic foam.
Acoustic foam vs regular foam
Acoustic foam and regular foam are two different types of foam that have different properties and uses.
Regular foam, also known as polyurethane foam, is a type of foam that is commonly used in furniture, cushions, and bedding. It is made from a mixture of chemicals that are poured into a mold and allowed to expand and cure. Regular foam is used primarily for its comfort and support properties, and it can be made in various densities.
Acoustic foam, on the other hand, is a type of foam that is specifically designed to improve the acoustics of a room by absorbing sound waves. It is typically made from a type of polyurethane foam that has been treated with special chemicals or coatings to increase its sound-absorbing properties. Acoustic foam is often used in recording studios, home theaters, and other spaces where sound quality is important.
In summary, regular foam is primarily used for comfort and support, while acoustic foam is used to improve the acoustics of a room by absorbing sound.
How About Mattress Toppers?
Here is where it gets interesting, Mattress toppers give a higher success rate for sound dampening. Notice I used the word dampening and no soundproofing.
If you line complex services in your studio or room where you need some help with your acoustics, mattress toppers will stop echo and reverberation.
They still let a lot of the sound through, but if you are recording and want to stop the sound waves bouncing off hard surfaces, the mattress topper will work fine.
It appears as if a mattress topper could be the ideal medium to use in a studio where a podcast is being recorded.
The sound absorption qualities seem to absorb speech echo perfectly.
The Bottom Line
You will only achieve perfection with soundproofing if you spend a lot of money, as previously said, soundproofing is a science and commands a high price.
Mattress toppers will give most of you the desired effect you are looking for.
