Final answer:
Equalization does alter the harmonic structure of a sound by adjusting the levels of different frequencies to achieve a desired tonal balance.
Step-by-step explanation:
Equalization does alter the harmonic structure of a sound. This process involves adjusting the relative levels of different frequencies in a sound to achieve a desired tonal balance. By boosting or attenuating specific frequencies, equalization can enhance or reduce the presence of harmonics, which are multiples of the fundamental frequency. For example, if you boost the higher frequencies in a sound, you can emphasize the higher harmonics and make the sound brighter or more intense.
However, it's important to note that equalization does not change the fundamental frequency itself or create new harmonics. It only affects the balance and perception of existing harmonics in a sound.
So, the statement that equalization alters the harmonic structure of a sound is True.
