The study of sound and its properties.

Vibrations that travel through matter and can be heard.

Rapid back-and-forth motion that produces sound.

A thin membrane that vibrates in response to sound waves.

A spiral-shaped part of the inner ear that converts sound waves to electrical signals.

A tube that equalizes pressure between the ear and the environment.

The part of the brain that interprets sound signals.

There is no sound in a vacuum because sound needs a medium to travel.

A tone is a smooth oscillation, perceived as pleasant and harmonious.

Noise is an uneven oscillation, perceived as unpleasant.

The fundamental is the lowest frequency of a sound, determining the main pitch.

Overtones are higher frequencies created alongside the fundamental, adding richness to sound.

Frequency refers to the number of oscillations per second in a sound, measured in Hertz (Hz).

Resonance amplifies sound through vibrations within a hollow space, enhancing its volume.

The C Major scale is a sequence of notes that forms a major scale, often a starting point in music.

A tuning fork is a tool used to produce a specific pitch for tuning musical instruments.

Structures built to reduce traffic noise between roads and houses.

Devices that reduce noise from machines in industries.

Devices or methods to protect against loud sounds.

Person responsible for monitoring noise in workplaces.

Unwanted sounds causing annoyance or stress.

Sounds that are below the frequency audible to humans.

Material used to prevent sound from traveling between rooms.

Loud sounds generated during building activities.
