D. It is not affected by different materials
C. Different materials absorb or reflect sound
Different materials can affect sound in various ways, such as absorbing, reflecting, or transmitting it differently. For example, materials like soft fabrics or foam tend to absorb sound, resulting in less reverberation and a quieter environment. On the other hand, hard surfaces like glass or metal can reflect sound, causing echoes and amplifying the overall volume. This is why the acoustics of a room can vary depending on its construction materials.
