Acoustic Curtains vs Soundproof Curtains: What’s the Real Difference?

Acoustic curtains are used to reduce the noise inside a room. They are composed of dense and thick fabrics such as wool or fibreglass. These materials absorb the inside noise and create a peaceful place. On the contrary, soundproof curtains are also used to lessen the noise or unwanted echoes. However, they are composed of multiple layers, such as mass-loaded vinyl or foam.

These materials block the transmission of outside noise into your space. Both soundproof and acoustic curtains help in noise reduction. The major difference between these two types is that acoustic drapes absorb noise within a space. Soundproof curtains restrict the outside noise from entering your space.

If you are still confused about them, we are going to describe acoustic curtains vs soundproof curtains: what’s the real difference? Maintain focus till the last line to clear the difference between these two types of curtains.

Before moving forward, let’s understand the basic concepts of sound absorption and soundproofing:

What is Sound Absorption?

Sound absorption is the quality of curtains that reduces echoes in a space. For this purpose, soft, porous materials such as wool or foam are used. In simple terms, sound absorption reduces or eliminates internal sound.

What is Sound Proofing

Soundproofing is about blocking the transmission of outside sounds, such as airport or traffic noise. For this purpose, multiple layers of fabric and dense materials such as mass-loaded vinyl are used. In simple words, soundproofing restricts the external noise from entering the space.

Here are some key differences between acoustic and soundproof curtains. Let’s explore them one by one:

1. Sound Absorption vs Sound Blocking

As the name suggests, sound absorption curtains are used to reduce noise. These window drapes are designed to dampen interior echoes from the outside environment. They have a high Noise Reduction Coefficient ( NRC). This rating determines how efficiently these curtains reduce the noise. Therefore, they can be used as bedroom curtains to create a quieter and more peaceful atmosphere.

On the other hand, soundproofing curtains are used to block the sounds. These drapes are composed of multiple layers that block the sounds from entering or leaving the space. They have a high Sound Transmission Class (STC). This rating decides their sound-blocking ability.

2. Material Composition

Acoustic curtains are made from soft and porous materials such as velvet and cotton. These window drapes feature double layers of fabric to create pleats for sound absorption. That’s why they are an ideal choice as office curtains.

On the contrary, soundproof curtains are composed of dense and heavy materials such as foam or mass-loaded vinyl (MLV). Additionally, these are designed with multiple layers of fabrics to create heavy curtains for excellent sound blockage.

3. Weight and Thickness

Sound-absorbing drapes are made of a light fabric. Therefore, these are lighter in weight and add an airy feel to your space while absorbing the unwanted sounds. Because of their low density, you can use silk curtains to make acoustic curtains. Beyond their functionality, sound-dampening curtains are aesthetically appealing and captivating.

On the other hand, soundproof curtains are made of dense and thick fabrics. Therefore, they are thick and heavy, and excellent at blocking noise. However, they are not very visually appealing or elegant.

4. Effectiveness in Noise Reduction

As we have already mentioned, acoustic curtains are designed to dampen sound within a space. On the other hand, soundproof drapes are crafted to block the sounds from entering or leaving the space. Due to their thick, dense fabrics, blackout curtains are commonly used to make soundproof curtains.

5. Price Comparison

Acoustic window curtains are available at cost-effective rates. Additionally, these drapes are available in a wide variety of shades, designs, and patterns. On the other hand, soundproof curtains are more expensive than acoustic curtains because of their complex composition. Additionally, these curtains are designed with advanced technologies and may not be available in a variety of designs and patterns.

6. Applications

Soundproof curtains are used to block the echoes from the outside construction, aircraft, or traffic. Therefore, they are a great choice for recording studios and home theatres. On the contrary, acoustic curtains are used to control reverberation and noise. So, you can apply these curtains in music studios or theatres.

Now, the important question is when you should choose acoustic curtains or soundproof curtains:

Choose Acoustic Curtains If

• You want to reduce the sounds inside a room.
• You want to create a peaceful environment in your bedroom.
• You need a better sleep atmosphere.
• You have a home office or media room.
• You are looking for both elegance and comfort

Choose Soundproof Curtains If

• You want to block the transmission of inside or outside noise.
• Your home is near a traffic or construction area.
• You need privacy and noise isolation.
• You have a recording studio or home theatre.
• Your main concern is sound blockage.

There are some common myths about soundproof curtains. A few of them are mentioned here:

• All thick curtains are soundproof.
• Curtains block all the echoes.
• There is no difference between acoustic and soundproof curtains.
• They are only for windows.
• They require no specific installation.

Acoustic curtains are crafted to muffle the inside noise. They are made of double-layered fabrics such as cotton or velvet. These curtains are aesthetically appealing, perfect for home offices and media rooms. On the other hand, soundproof curtains are designed to block the sounds from entering or leaving the space. They have multiple layers and are made of thick and dense fabrics such as mass-loaded vinyl. Apparently, they are less appealing than sound-dampening curtains. But their Sound Transmission Class (STC) rating is very high, making them ideal for nurseries and studios.
