Sound insulation or sound absorption
When you want to improve the acoustics of a room, you often come across terms like sound absorption and sound insulation. Although these concepts are sometimes confused with each other, each has its own function and application. By understanding the difference well, you can make the right choices for optimal sound control. Read here what sound absorption and sound insulation actually mean, when to apply them, and which materials are most suitable.
What is sound absorption?
Sound absorption is about improving the acoustics within a space. It helps reduce reverberation and echoes by absorbing sound waves with acoustic materials. These sound waves are converted into (negligible) heat, preventing them from reflecting back.
What does sound absorption provide you with?
- Less reverberation and echoes.
- Better speech intelligibility.
- A comfortable, pleasant environment.
Examples of sound-absorbing materials
- Acoustic foam: Sound-absorbing material that reduces reflections and absorbs sound waves.
- Soft textiles: Carpets, curtains, and upholstered furniture help to dampen sound.
Tips to improve sound absorption
- Use soft materials: Carpets, curtains, and upholstered furniture contribute to sound dampening.
- Place absorbing panels strategically: Focus on walls and ceilings where sound is often reflected. Place absorbing materials there.
What is sound insulation?
Sound insulation helps to prevent sound from being transmitted between spaces. This allows you to block out external noise or keep sound within a specific room, such as a bedroom or music studio.
Two types of sound you may encounter:
- Airborne sound: Sounds such as music, voices or traffic.
- Impact sound: Sound that occurs due to vibrations, such as footsteps, a washing machine or a slamming door.
Both types of sound can be reduced with a false wall.
Examples of soundproofing materials
- Cyclin Pure: A sustainable acoustic insulation for floors, walls, and roofs.
- Cyclin Partition Board: A sustainable insulation panel for creating a partition wall.
- Mass Panels: Sound-insulating mass panels have a high mass and limited thickness, making them suitable for improving sound insulation, for example, in wooden floors.
- Damping Plates: These plates absorb vibrations in metal structures, reducing resonance.
Tips to improve sound insulation
1. Use heavy materials: The denser and heavier the material, the better the sound will be insulated.
2. Install a partition wall: This reduces sound vibrations from one wall to another.
3. Seal gaps and cracks: Sound often finds its way through small openings.
What is the difference between sound insulation and sound absorption?
Although sound absorption and sound insulation can complement each other, they each serve a different purpose. Sound absorption focuses on improving the acoustics within a space. This is achieved by dampening sound waves. Sound insulation, on the other hand, prevents sound from travelling from one room to another. By cleverly combining these techniques, you can both reduce noise disturbances and create a quiet and pleasant environment.
