Can cardboard block noise?

In this article, we will discuss the ability of cardboard blocks to make noise. Many have asked, so many don’t know the answer. 

Many people that have tried to use cardboard boxes as noise blockers can attest to the fact that they are not very effective. Instead of providing any level of sound reduction, they actually make the noises that they were intended to block much louder than before. 

So the question remains: Can cardboard blocks truly act as effective noise blockers?

Cardboards don’t block sound, neither they are great sound absorbers but they can be used to reduce the transfer of sounds/noises and reduce echoes.

For centuries, people have experimented with ways to make noise with blocks of cardboard, and occasionally, they’ve found it works better than you would expect! 

In this article, we’ll look at some of the ways you can make noise with cardboard blocks and we’ll cover a few other surprising ways you can use these boxes in your everyday life.

How cardboard blocks noise?

While the material cardboard is not in itself capable of making sound, it can be used to reinforce another object’s ability to produce sound. 

For example, when a violin string is plucked, the vibrations travel up and down the string and into the violin body where they vibrate the violin bridge. This movement causes a flexible piece of wood called a ‘soundpost’ to vibrate which then transmits the vibration to the instrument’s resonant body or ‘sound box’. 

In this case, because resonance is created by vibrations in solid objects, and because cardboard does not produce its own resonance, vibration from strings will not cause any movement in a piece of cardboard.

What material is best for blocking sound? 

Sound waves can be blocked using materials like soundproofing insulation, fiberglass, polyurethane foam, and even cardboard. When looking to create a soundproofed room or space, it is important to consider what material will be the most effective for your needs. 

Thick solid materials help in blocking sound, for example, most of the homes in US have hollow core doors which are not very good with soundproofing. Installing solid core doors could help more in blocking sound and make the room isolated.

You can use soundproof window inserts to block the sound coming through the windows.

What can I use to soundproof cheaply? 

In many cases, soundproofing an apartment or home can be as easy as adding insulation and blocking windows & door. The first step is to make sure you are insulating your walls, ceilings, and floors. 

For example, drywall is not enough; you need to attach it to the wall with screws and metal strips. Next, make sure that there are no gaps between the drywall and window frames. 

Finally, find a way to stop sound from traveling through your windows. If you have an air conditioner in the bedroom, for example, move it into the living room during winter months so that it does not blow cold air into your bedroom all night long.

Benefits of blocking noise with cardboard

I won’t recommend using cardboards as they are ineffective but if you have an open window and you got nothing to cover it, go for cardboard. For one, it can help keep your neighbors from hearing you play music or watch TV late at night. 

It also means that you don’t have to worry about other people’s conversations being overheard. And if you live in an area that’s prone to natural disasters, using cheap and readily available materials like cardboard can make all the difference in protecting your belongings from the elements.
