1.1.1 Determinants of the sound field
A sound source placed in a closed space generally radiates in all directions.
Sound waves propagate towards the limits of the volume, coming into contact with walls or obstacles. Their behavior obeys laws that depend mainly on the characteristics of the emitted signal and the impedance of the materials encountered.
The main factors involved in the structure of the radiated field are (figure
