## What are the 3 sound absorption techniques?
1. **Soft furnishings**: Soft materials like carpets, curtains, and upholstered furniture absorb sound waves.
2. **Acoustic panels**: These are specially designed panels that are placed on walls or ceilings to absorb sound.
3. **Plants**: Indoor plants can help absorb sound waves and reduce echo in a room.
## Explanation.
Sound absorption techniques are methods used to reduce the amount of sound that bounces off surfaces in a room, which can help reduce noise levels and improve acoustics. .
1. **Soft furnishings**: Soft materials like carpets, curtains, and upholstered furniture absorb sound waves by preventing them from bouncing off hard surfaces and creating echoes. These materials are able to absorb sound due to their texture and density, making them effective at reducing noise levels in a room.
2. **Acoustic panels**: Acoustic panels are specially designed panels that are made from materials that absorb sound waves. These panels are often placed on walls or ceilings in rooms that have poor acoustics. They work by trapping sound waves and preventing them from bouncing around the room, helping to reduce noise levels and improve the overall sound quality in a space.
3. **Plants**: Indoor plants can also help absorb sound waves and reduce echo in a room. The leaves and branches of plants can help to scatter sound waves, preventing them from bouncing off hard surfaces. Additionally, plants can help to add a natural element to a room while also providing the added benefit of improving air quality.
Overall, using a combination of these sound absorption techniques can help to create a more pleasant and acoustically sound environment. By strategically placing soft furnishings, acoustic panels, and indoor plants in a room, it is possible to reduce noise levels, minimize echoes, and improve the overall sound quality of a space.
