WebCheck Your Understanding. 1. A sound wave is a pressure wave; regions of high (compressions) and low pressure (rarefactions) are established as the result of the vibrations of the sound source. These compressions and rarefactions result because sound. a. is more dense than air and thus has more inertia, causing the bunching up of sound. WebAug 7, 2024 · The conventional tool for measuring air pressure is a barometer, but because the pressure differential between rooms is typically very small compared to the overall room pressure, a barometer isn't sensitive enough to measure room pressure differentials. The tool used by most HVAC technicians is a digital manometer.
WebAir pressure can simply be measured with a barometer by measuring how the level of a liquid changes due to different weather conditions. In order that we don't have columns of liquid many feet tall, it is best to use a column of mercury, a dense liquid. The aneroid barometer measures air pressure without the use of liquid by using a partially ...
