sound engineering

Voice is considered one of the important means of communication between humans, and humans rely on it to communicate, converse, express opinions, and express precious feelings. God created hearing and sight to complement each other. It is not necessarily what the eye sees that the ear hears. We may look at the swimming pool and see children having fun while we hear the sounds of calls or ship whistles or the sound of something else that we are thinking about.

Fluid mechanics

It is a sub-specialization of the mechanics of continuous materials and is mainly concerned with fluids, which are mainly liquids and gases. This specialization studies the overall apparent physical behavior of these materials, and it can be divided on the one hand into fluid statics - or studying them in a state of immobility, or fluid dynamics - or studying them in a state of Movement, and certain other specializations fall under it, there are aerodynamics (aerodynamics) and water dynamics (hydrodynamics).
