Abstract

Abstract:
After the great technological development and its entry as a basic component in contemporary buildings, the importance of the architect's knowledge of various sciences outside his specialization. The necessity of this stems from the fact that these modern components greatly affect the comfort of the user of architectural spaces.
Among these modern elements, air conditioning in buildings. These elements have become necessary and indispensable to provide comfort to building users, and on the other hand, these devices cause loud noises during their operation, which causes noise that harms the user and harms his hearing comfort.
This research discusses the issue from all its aspects and presents the types of these devices and their mechanisms of action and how to provide barriers that prevent the transmission of noise inside buildings so that the user of architectural spaces enjoys thermal and audio comfort at the same time.

Heating, Ventilation and Air Conditioning Systems (HVAC) produce serious environmental noise pollution outdoor and indoor. Outdoor noise generated by
