Tip: Proper installation (sealed joints, careful finishing) is crucial to maximise performance. For tailored solutions, consider professional advice.
Why STC Ratings Are Critical When Soundproofing!
1. Basic Single-Layer Drywall
Basic single-layer drywall consists of a single 12.5 mm gypsum board attached to either metal or wooden studs. This straightforward design impacts its soundproofing ability, typically providing an STC rating of 33–35. This means that while it can reduce sound, normal speech can still be heard to some extent.
2. Insulated Stud Wall
Insulated stud walls take the basic drywall setup a step further by providing better noise reduction. They are a popular choice for spaces like home theatres, recording studios, and offices where managing sound is crucial. These walls are designed to minimise noise transfer, creating a quieter and more controlled environment.
Applications
Here are some common uses for insulated stud walls:
| Setting | Main Advantage | Common Purpose |
|---|---|---|
| Home Theatres | Reduces outside noise for better sound | Building immersive cinema experiences |
| Recording Studios | Improves acoustic quality | Ensuring high-quality audio recordings |
| Office Spaces | Increases privacy | Supporting confidential conversations |

3. Sound-Rated Drywall
Sound-rated drywall takes noise control to the next level, offering a more effective solution for acoustic challenges compared to basic or insulated walls. It’s designed specifically to deliver better soundproofing for demanding environments.
STC Rating
With proper insulation and spacing, sound-rated drywall can achieve impressive STC (Sound Transmission Class) ratings of 60-65. This makes it a great option for spaces where controlling noise is a top priority.
Cost
Here’s a breakdown of costs and performance for different drywall options:
| Configuration Type | Cost per m² | STC Rating Range |
|---|---|---|
| Basic Single Layer | £15-20 | 30-35 |
| Standard Double Layer | £25-35 | 40-45 |
| Sound-Rated Single Layer | £35-45 | 45-50 |
| Sound-Rated Double Layer | £55-70 | 55-65 |
Applications
Sound-rated drywall is ideal for specialised environments where noise control is crucial. Below are some common applications:
| Setting | Primary Benefit | Typical STC Achievement |
|---|---|---|
| Commercial Offices | Better speech privacy | 50-55 STC |
| Recording Studios | High-level sound isolation | 60-65 STC |
| Heritage Buildings | Improved acoustics without altering structure | 45-55 STC |
| Home Theatres | Enhanced viewing and listening experience | 55-60 STC |
Ease of Installation
Proper installation is key to getting the most out of sound-rated drywall. Here are some essential tips:
- Seal joints: Use acoustic sealant to ensure no gaps for sound to pass through.
- Finish fixtures carefully: Pay close attention to areas like electrical boxes to avoid sound leaks.
- Hire professionals: Expert installers can ensure the drywall performs as intended.
Sound of Silence offers professional consultation and installation services to help you achieve the best possible noise reduction.
Benefits and Limitations
The table below outlines the acoustic advantages and disadvantages of different drywall configurations, helping you make an informed choice:
| Configuration | Acoustic Advantages | Acoustic Drawbacks |
|---|---|---|
| Basic Single-Layer | Works well in low-noise environments | Limited sound isolation (STC 30–35); poor low-frequency control |
| Insulated Stud Wall | Offers moderate noise control with better STC (40–45) | Doesn’t provide high levels of noise reduction |
| Sound-Rated Single Layer | Reliable acoustic performance with STC (45–50) | Not ideal for retrofitting; structural changes may be required |
| Sound-Rated Double Layer | Excellent sound isolation (STC 55–65) and strong low-frequency control | Thicker walls may reduce room space |
This comparison can guide you in selecting the drywall configuration that aligns with your soundproofing requirements.
Final Comparison
Here’s a summary of the key findings from our STC rating analysis, presented to help you choose the right configuration for your space.
Configuration Recommendations by Environment
| Environment | Recommended Configuration | Expected STC | Best Suited For |
|---|---|---|---|
| Standard Bedrooms | Basic Single-Layer | 30–35 | Quiet residential areas with minimal external noise |
| Home Offices | Insulated Stud Wall | 40–45 | Remote workspaces needing moderate sound isolation |
| Media Rooms | Sound-Rated Single Layer | 45–50 | Entertainment spaces with moderate audio equipment |
| Home Theatres | Sound-Rated Double Layer | 55–65 | Areas requiring high-level sound isolation |
This table helps you match your acoustic needs with the right performance level, making the selection process straightforward.
Key Considerations for Configuration Selection
Each configuration addresses specific noise challenges, from quiet residential bedrooms to high-performance home theatres. For example, insulated stud walls are ideal for home offices, offering enough isolation for video calls and focused tasks. Meanwhile, media rooms and home theatres benefit from sound-rated layers to manage sound effectively.
When deciding on the best setup, consider the following:
- Room Purpose: Match the configuration to how the space will be used.
- External Noise Levels: Check for factors like nearby roads or neighbouring properties.
- Budget: Balance the cost of installation with the level of sound control you need.
- Space Constraints: Keep in mind that thicker walls might reduce room size.

FAQs
How do STC ratings influence the choice of drywall for different types of rooms?
STC (Sound Transmission Class) ratings measure how effectively a wall, ceiling, or floor reduces sound transmission. When selecting drywall, the STC rating is crucial as it determines the level of soundproofing required for a specific space.
For instance, bedrooms and home offices may need higher STC-rated drywall to minimise noise from adjacent rooms, ensuring privacy and focus. In contrast, living rooms or communal areas might not require as much sound insulation. For cinemas, recording studios, or auditoriums, extremely high STC ratings are essential to prevent sound leakage and maintain acoustic quality.
Understanding the STC rating of various drywall configurations can help you make an informed decision tailored to your needs, whether for residential, commercial, or industrial spaces.
What should I consider when installing sound-rated drywall for optimal soundproofing?
To achieve the best soundproofing results with sound-rated drywall, there are a few key factors to keep in mind:
- Drywall configuration: Choose the right combination of drywall layers, insulation, and resilient channels to maximise the Sound Transmission Class (STC) rating.
- Sealing gaps: Ensure all gaps, cracks, and seams are sealed with acoustic caulk or sealant to prevent sound leakage.
- Installation technique: Properly install resilient channels or sound isolation clips to reduce vibrations and improve soundproofing performance.
Paying attention to these details can significantly enhance the acoustic performance of your space, whether it’s a home, office, or studio.
Can soundproof drywall configurations be added to existing spaces, and what challenges might arise?
Yes, soundproof drywall configurations can be retrofitted into existing spaces, but there are some challenges to consider. Retrofitting often involves modifying existing structures, which may require additional framing, adjustments to door and window seals, or addressing gaps and leaks that could compromise soundproofing effectiveness.
Potential challenges include limited space for adding extra layers of drywall, increased costs for materials and labour, and the need to ensure compatibility with existing walls and finishes. It’s also essential to consider how the added weight might affect the structural integrity of the building. Consulting with an acoustic specialist can help you identify the best approach and minimise potential issues.
