Final answer:
The "loudness war" is about the trend of increasing the volume of music in production, leading to increased loudness and reduced dynamic range. It is associated with amplitude and measured in decibels, not frequency, which determines pitch.
Step-by-step explanation:
The "loudness war" refers to a phenomenon in the music industry where there is a trend of increasing the volume of music through various production techniques, which results in a reduction of audio dynamic range. The correct answer to the question posed is B) Increased volume. This war has led to criticism as it can lead to reduced sound quality and listener fatigue.
Loudness is often confused with frequency, but they are different concepts. Loudness is related to the intensity or amplitude of sound and is typically measured in decibels. On the other hand, frequency, which determines the pitch of the sound, is the number of waves that pass a point in a second (measured in Hertz).
Increasing the amplitude of a sound wave makes it louder, but does not change its frequency. A higher frequency results in a higher pitch, but not necessarily a louder sound. The loudness war is about the perceived volume of music, not its pitch (frequency).
