Hello I am interested in calculating the sound waves created by objects in air. What is the resolution of details that needs to be dealt with in orer to calculate this? Can it be calculated by using traits of the object such as mass density, geometry and other related attributes? Or do you need to deal in the level of particles and behaviour of small particles such as atoms? Where there is reference material on this subject? books etc? I would appreaciate your help on this matter. Thanks in advance.
