Sound
In this course we will learn more about the path sound takes. The sound travels through a medium in the form of spherical pressure waves. We have assumed that it is evenly distributed in all directions, assuming the source to be a point source.
Now let us find out more about the path sound takes.
The sound travels through a medium in the form of spherical pressure waves. We have assumed that it is evenly distributed in all directions, assuming the source to be a point source.
As said earlier, we aim to be able to create good hearing conditions in the spaces we design. The first important to observe is to see that the sound in “the Best Path” reaches the listener.
We are trying to analyze the issue considering that all sound incidences are wanted to be heard and we are not discussing unwanted sounds which we want to keep away. Thus we have to find the best path of the sound takes when released from the source.
Every source of sound, because of the shape-form-construction of the sounding object, does not radiate sound exactly equal in all directions. We will always experience that the intensity dispersed in a certain direction is better than the other directions. For example if we consider a person speaking.
The intensity in the front direction will be more than the intensity behind him or on either side because though the sound is generated in the voice-box in our mouth, the inside hollow space in the mouth adds reinforcement to the sound from reflections on the walls of hollow of our mouth.
