Unlock Serenity: Acoustical Curtains for Noise Reduction Excellence

Soundproof curtains sound like an incredible innovation. How much do they really reduce noise coming from outside the room?

Soundproof curtains do not entirely block out outside noise. However, they reduce the intensity of the sound and make the room significantly quieter. The materials that compose soundproof curtains effectively reduce noise by absorbing the vibrations in the air that create sound. 

Check out my top recommendations for soundproof curtains.

How Much Do Soundproof Curtains Reduce Noise

This article will cover the essential qualities of soundproof curtains, in addition to the different types. Read on to learn more about the advantages and disadvantages of soundproof curtains.

Soundproof curtains can reduce noise to a whisper. They absorb echo and vibrations inside the room and reduce sound decibels from outside to a bearable degree. The higher the curtain’s STC rating, the more noise it can reduce.

How Soundproof Curtains Differ From Other Curtains

Many people think that every thick curtain is soundproof. However, this assumption is incorrect. Although thick curtains tend to reduce noise, they’re not all soundproof. Soundproof curtains have certain features that distinguish them from other curtains.

Generally, soundproof curtains differ from other curtains in the following ways:

  • Material
  • STC ratings
  • Length of curtains
  • Width of curtains

Let’s consider each of these factors one by one.

Dense Materials Allow for Soundproofing

Soundproof curtains are mostly made with suede, polyester, or velvet materials. They’re heavy materials with a tight weave.

These materials have a thermal property that makes the curtains absorb and retain heat. As a result, they will keep your room cooler in the summer and warmer in the winter.

STC Ratings Identify Soundproof Curtains

Noise reducing curtains have a property called Sound Transmission Class (STC) rating. This feature distinguishes soundproof curtains from other curtains.

Soundproof curtains with an STC rating can reduce sound penetration from the external environment by 80%.

Length Impacts Effective Soundproofing

It may come as a surprise that the length of your curtain can impact how soundproof they are. Soundproof curtains go all the way from the ceiling to the floor. 

You can use a ceiling bracket to install your curtain rod. This ensures that the curtain is as close to the ceiling as possible.

Width Affects Degree of Soundproofing

Soundproof curtains are wide enough to cover more than just the window. These curtains are often slightly wider than the window by at least 3 inches (7.62 cm) or more, and they fold at the edges. 

The wider the curtain extends beyond the window and folds, the more sound penetration prevention it can achieve. However, some sounds can escape near the edges of the curtains.

Types of Soundproof Curtains

Acoustical curtains for reducing have several names. However, there are only two rating systems that distinguish all soundproof curtains:

  • Sound Transmission Class (STC) rating
  • Noise Reduction Coefficient (NRC) rating

Although these ratings both consider the amount of noise a material can block, they have a few key differences.

The STC Rating Considers Noise From Outside the Room

The STC rating determines the number of decibels a soundproof curtain can block from the outside. STC-rated materials are dense and heavy, allowing them to block outside noise.

If you can’t locate an STC rating on your soundproof curtains, look at how heavy or thick the material is compared to others. This will help you gauge how successful they are at soundproofing.

The NRC Rating Considers Noise From Within the Room

The NRC rating defines how much noise the curtain can absorb within the room. 

An NRC-rated soundproof curtain is usually lightweight, porous, and fluffy. These properties enable them to effectively absorb sound. So, if the echo and reverberation in your room are bothersome, an NRC-rated curtain will help you absorb all of the excess noise. 

It’s worth noting that NRC-rated drapes don’t block out outside noise. They solely absorb sound waves from within.

Advantages and Disadvantages of Soundproof Curtains

Soundproof curtains help us manage both external and internal noise. However, they also present some challenges. Let’s analyze the pros and cons of using soundproof curtains.

Advantages of Acoustical Curtains For Reducing Noise

Here are some merits of using soundproof curtains:

  • Soundproof curtains reduce noise and heat. Soundproof curtains diminish outside noise, absorb echoes and vibrations, and reduce the intensity of sunlight. If you want to nap in the afternoon, close your soundproof curtains and enjoy the stillness and comfortably cool temperatures.
  • Noise absorbing curtains are inexpensive and come in a variety. You don’t need to break the bank to get some soundproof curtains of your own. In addition, they’re made of various materials, many of which offer your home a novel, classy appearance. No matter your budget, you can acquire a soundproof curtain and make your home more comfortable.
  • Acoustical curtains for reducing noise provide privacy. Some windows face the street or public areas. While the view may be nice, it’s understandable that you want some privacy. The soundproof curtains provide seclusion by fully covering the view and reducing the strength of the sun rays, making your room feel more comfortable. It also delivers a sense of calm and relaxation, making you feel at ease.

Disadvantages of Noise Absorbing Curtains

Here are some disadvantages to using soundproof curtains:

  • Soundproof curtains are difficult to install. Soundproof curtains, especially those with an STC rating, can be difficult to install. If you can’t handle the installation process on your own, seek professional assistance.
  • Soundproof curtains pose a logistical challenge. Soundproof curtains are heavy and bulky. Moving them from the point of sale to the owner’s residence may take a lot of effort and time. 
  • Soundproof curtains are difficult to wash and maintain. After a month or two of use, the soundproof curtain, like any other cloth, will need washing. However, they can be difficult to wash, and often require particular detergents. Because the materials differ, it’s essential to wash them using the appropriate detergents. Before you get a soundproof curtain, consider how you’ll clean and care for it to get the most out of it.
  • Soundproof curtains create darkness. Installing soundproof curtains in your office can make it too dim. This limits the places where you can use soundproof curtains. So, if you need a little sunlight but less noise, a soundproof curtain likely isn’t the right solution for you.


Soundproof curtains can significantly reduce noise to a minimum. They block external noise, diminish sunlight, and absorb internal echo and reverberations.

Soundproof curtains come in two types based on STC and NRC ratings. STC stands for sound transmission coefficient, and it measures how much a curtain blocks external sound from entering the room. 

On the other hand, NRC stands for noise reduction coefficient and measures how much can absorb and reduce internal noise from echoes and reverberations.
