Keyword: «acoustic resistance»

The paper focuses on some issues of basic physics for building acoustics that are not included (or just mentioned) in the general physics program. Taking into consideration the importance of building elements (thickness, material, presence of cavities) for acoustics environment formation the author considers the processes of acoustic waves interaction with solid bodies which affect people’s acoustic comfort in premises of various applications. The paper deals with phase and energy relations resulting from acoustic waves transfer from one medium into another with regard to sound environmental resistance. Reverberation processes affecting acoustic fields quality are also considered.
