The physical boundary that separates the interior of a building from the external environment. It includes exterior walls, windows, doors, roof, and foundation.
Acoustic Impedance is a measure of the resistance that a material or medium presents to the transmission of sound waves. It plays a crucial role in understanding the interaction of sound with surfaces and boundaries in acoustics and ultrasound imaging.
A sound barrier is a structure designed to reduce or block the transmission of noise from one area to another. It serves as a physical barrier that helps mitigate the impact of noise pollution in urban, industrial, and transportation settings.
A sound source is any object or device that generates vibrations, producing acoustic waves or sound. Understanding sound sources is essential in the study of acoustics and sound engineering.
The Zone Pressure Test assesses airtightness and pressure relationships between different zones in a building. Discover how this test identifies air leakage, verifies compartmentalization measures, and guides improvements in energy efficiency and compliance with building codes.
