- - - - the best place for absorption is the ceiling or high up on the walls.(Cox T., D'Antonio P., 2016)
      - Absorption occurs when a sound wave is absorbed by the object or material it encounters. A sound wave that is absorbed transforms into heat energy inside the object or material absorbing it. (Bosnyak et al., 2021)
    - - Diffusion typically occurs when the texture and hardness of the object or material is similar to the sound’s wavelength. Exactly how the sound diffuses depends on the nature of the surface texture. Too much diffusion can make it difficult to localise where a sound is coming from. Diffusion occurs when a sound wave diffuses or scatters in different directions upon encountering an object or material. (Bosnyak et al., 2021)
