Volume and Amplitude

Front

What is the definition of amplitude in the context of sound waves?

Back

Amplitude refers to the maximum extent of a vibration or oscillation, measured from the position of equilibrium. In sound waves, it relates to the loudness of the sound.

Front

How does amplitude affect the volume of a sound?

Back

Higher amplitude results in louder sounds, while lower amplitude results in softer sounds.

Front

What unit is used to measure sound volume?

Back

Volume is measured in decibels (dB).

Front

What is the relationship between sound amplitude and energy?

Back

Higher amplitude sound waves carry more energy, while lower amplitude sound waves carry less energy.

Front

What type of sound wave is produced when someone shouts?

Back

A shouting sound is represented by a wave with high amplitude.

Front

What type of sound wave is associated with a whisper?

Back

A whisper is carried by sound waves with smaller amplitude.

Front

What is the difference between volume and loudness?

Back

Volume is a quantitative measure of sound intensity, while loudness is a subjective perception of that intensity.

Front

What factors can affect the perceived volume of a sound?

Back

Factors include the distance from the sound source, the environment (e.g., acoustics), and individual hearing sensitivity.

Front

What is the formula for calculating sound intensity?

Back

Sound intensity (I) is calculated as power (P) per unit area (A), I = P/A.

Front

How does distance from a sound source affect sound volume?

Back

As distance from the sound source increases, the volume of the sound decreases due to the spreading of sound waves.
