What to Look For Before Buying

Choosing the right soundproofing blanket requires careful consideration of your specific room needs. Look for high-density materials that effectively absorb reflections rather than just blocking sound.

Check Material Density and Weight

Density is the most important factor for effective sound absorption. Heavier, thicker blankets made of cotton batting or synthetic fibers absorb more sound waves. Always check the weight of the blanket to ensure your walls can support it.

Value Coverage Area

Measure your space accurately before purchasing any acoustic blankets. You need enough coverage to treat the primary reflection points in your room. If you are treating a door, look for a custom-sized blanket. For large walls, consider using multiple blankets to ensure complete coverage.

Rating Installation Hardware

Consider how you will hang your blankets before you buy. Grommets are the most convenient option for walls and windows. Some blankets come with adhesive strips or hooks for doors.

Verify Safety and Maintenance

Look for non-toxic materials, especially if you are working in a small, enclosed space. Avoid fiberglass if you have health concerns or sensitive skin. Check if the blanket is machine washable to keep your studio clean over time. A durable, washable blanket will last significantly longer.
