Acoustics is the study of sound, including the properties of sound waves and their interactions with different media. It covers environmental noise pollution, musical acoustics, ultrasound technology, infrasound uses, and the impact of vibrations on structures. This field intersects with engineering, architecture, and healthcare, highlighting its broad applications in society.

Sound waves are longitudinal waves that cause periodic compressions and rarefactions in the medium they travel through
Infrasound and Ultrasound
Sounds outside the typical human auditory range, such as infrasound and ultrasound, have their own unique applications
This branch of acoustics assesses the impact of sound from sources like traffic, construction, and industrial operations on human health and wildlife
This field involves the analysis of how musical instruments generate sound, the structural composition of music, and the auditory perception of musical elements
High-frequency sound waves beyond the upper limit of human hearing are used for diagnostic imaging in the medical field and for non-destructive testing in industrial settings
Low-frequency sound waves are used for monitoring natural events and detecting man-made occurrences, aiding in geophysics and environmental studies
The study of vibrations and dynamics is crucial for understanding how mechanical oscillations affect the integrity and performance of structures and systems
Knowledge of vibrations and dynamics is applied to prevent resonance phenomena that can amplify vibrations and cause structural damage
Understanding vibrations and dynamics is essential for designing structures and systems that can withstand everyday stresses and extraordinary events, ensuring safety and durability

______ is the branch of science that deals with the study of sound, including the behavior of mechanical waves in different states of matter.
Acoustics
01
Sound wave propagation medium
Sound travels through air, water, solids via compressions and rarefactions.
02
Human auditory range in Hz
Humans hear sounds from 20 Hz to 20 kHz; below is infrasound, above is ultrasound.
