Living in an apartment has its advantages, but noise from neighbors, traffic, or even household appliances can affect your well-being.
The good news is that acoustic comfort can be achieved without major renovations. With sustainable materials, such as recycled PET panels and blankets, it is possible to reduce reverberation and improve sound quality inside the home.
In this article, you will understand:
- What is acoustic comfort and how does it differ from insulation?
- The main sources of noise in apartments;
- Sustainable solutions that can be easily implemented;
What NBR 15575 says about acoustic performance in residential buildings.
Acoustic comfort vs. sound insulation
Sound insulation → prevents sound from passing between rooms (building structure).
Acoustic comfort → deals with sound quality inside the apartment, reducing echo and reverberation.
Even if the building already has structural limitations, it is possible to improve the sound experience with lightweight and sustainable solutions.
Main sources of noise in apartments
- Footsteps and impacts coming from the upper floor.
- Conversations or music from neighbors.
- External noise (traffic, construction work).
- Reverberation in integrated rooms.
- Equipment such as air conditioning and household appliances.
Sustainable solutions for acoustic comfort
1. Recycled PET acoustic panels
- Attached to walls, they reduce echoes.
- Customizable in colors and formats.
- Sustainable and decorative.
2. Baffles and acoustic clouds
- Suspended from the ceiling.
- Ideal for integrated rooms and large spaces.
3. Acoustic blankets and linings
- Applied under floors or ceilings.
- They reduce impact noise.
4. Acoustic partitions and screens
- They create privacy in home offices.
- Lightweight and portable.
What does NBR 15575 say
NBR 15575 (Performance Standard) establishes acoustic standards for residential buildings:
- Minimum, intermediate, and advanced performance levels.
- Limites para ruídos aéreos e de impacto.
- The main responsibility lies with the construction company, but internal treatment complements performance.
FAQ
1. Do I need to break walls?
No. Lightweight solutions are applied to surfaces.
2. Is recycled PET efficient?
Yes, it works just as well as traditional materials, with the added benefit of being sustainable.
3. Does internal treatment replace structural insulation?
No, but it complements and improves sound performance.
Conclusion
Acoustic comfort is essential for well-being in apartments. With sustainable solutions, it is possible to reduce noise and create quieter environments without major construction work.
