Public address system Simple PA systems are often used in small venues such as school auditoriums, churches, and small bars. PA systems with many speakers are widely used to make announcements in public, institutional and commercial buildings and locations. Intercom systems, installed in many buildings, have microphones in many rooms allowing the occupants to respond to announcements.

How does the Respiratory System Work? This process of respiration is done through breathing. When we breathe in, the air or oxygen enters our respiratory system via the nose or mouth. The air then travels down to pass through the pharynx (back of the throat) and larynx or voice box (an organ in our neck involved in voice or sound production).he inhalation of oxygen and the exhalation of carbon dioxide are done via this system. Anatomically, the respiratory system can be described as a series of air passages or tubes of various sizes that help conduct air into the lung tissues (alveoli).

How It Works: The Air Compressor The power was routed around the work space by mechanical means. While the belts and shafts may be gone, many shops still use a mechanical system to move power around the shop. It's based on the energy stored in air that's under pressure, and the heart of the system is the air compressor. Advertisement-Continue Reading Below. You'll find air compressors used in a wide range of situations—from corner gas stations to major manufacturing plants.
