Materials such as foam panels, carpets, curtains, and acoustic tiles are known to absorb sound by reducing noise reflections. Soft surfaces have the ability to absorb sound waves rather than reflecting them back into the environment. Additionally, certain plants like ferns, rubber plants, and peace lilies have acoustic properties that can help absorb sound in indoor spaces.

Soft things absorb sound because their porous and fibrous structure allows them to trap sound waves, which then get converted into heat energy. The material's ability to dissipate and scatter the sound waves rather than reflect them helps reduce reverberation and echo in a space, leading to a quieter environment.
Yes, paper can absorb some amount of sound due to its porous nature. However, it is not as effective as other materials like foam or fabric in absorbing sound. Thicker and denser papers will absorb more sound than thin or lightweight papers.
Materials like acoustic foam, carpet, heavy curtains, and cork are known to absorb sound by reducing the reflection of sound waves. Additionally, objects such as bookshelves, upholstered furniture, and plants can help in absorbing sound due to their soft textures and uneven surfaces.
No, clocks do not absorb sound. Sound is typically reflected or transmitted through the materials that make up a clock, rather than being absorbed by it.
Yes, air can absorb sound to some extent. Sound waves travel through air by compressing and decompressing the air molecules. The absorption of sound in air increases with higher frequencies, longer distances, and the presence of obstacles in the sound path.
