**Purpose:**

To give the student a thorough comprehension of how
sound waves arise and

propagate.

**Contents:**

The wave equation and fundamental wave-theoretical
terms, definitions of pressure,

intensity, impedance, standard units, decibel scales.

Simple fields: plane waves, spherical waves,
cylindrical waves, free fields, and diffuse

fields. Absorption, reflection, refraction,

diffraction, transmission with loss.

Description of sources: point source, spherical
source, line source, monopole, dipole,

piston, sound source array, directivity, radiation

impedance.

Sound in simple enclosures: ducts, pipes, tubes,
guided waves, resonators, acoustical

filters, mufflers, ventilation systems. Electrical

analogues.

Introduction to: infrasound, ultrasound, and underwater
acoustics.

**Prerequisites:**

Basic skills in physics and mathematics. Partial
differential equations, complex

arithmetic.

**Duration:**

1 module
