Acoustics: Understanding the Science of Sound

Nature of Sound

Sound is a form of energy that travels through a medium via longitudinal waves, with properties such as frequency, amplitude, wavelength, and velocity.

Sound Properties

Frequency: The number of complete oscillations or cycles of a sound wave per second. Measured in Hertz (Hz).
Amplitude: The magnitude or intensity of a sound wave, determining its loudness. Measured in decibels (dB).
Wavelength: The distance between two successive points in a sound wave that are in phase with each other.
Velocity: The speed at which sound travels through a medium.

Sound Production

Sound can be produced by vibrating objects, musical instruments, vocal cords, and electronic devices.

Sound Transmission

Transmission of sound waves through different mediums and their interactions with obstacles, boundaries, and interfaces, including reflection, refraction, diffraction, and absorption.

Effects of Sound

Sound can induce resonance, create standing waves, cause interference patterns, and impact the environment and living organisms.

PHYSICAL SCIENCE (NGSS)

Matter and Its Interactions

Students who demonstrate understanding can:

Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.

Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
