What primarily affects the perceived loudness of a sound?
Understand the Problem
The question is asking about the factors that influence how loud a sound is perceived to be. The options provided suggest different aspects related to sound and its properties, focusing on which is the most significant in affecting perceived loudness.
Answer
The time-averaged energy of the waveform and frequency distribution of the signal primarily affect perceived loudness.
The perceived loudness of a sound is primarily determined by the time-averaged energy of the waveform and the frequency distribution of the signal.
Answer for screen readers
The perceived loudness of a sound is primarily determined by the time-averaged energy of the waveform and the frequency distribution of the signal.
More Information
Loudness perception is subjective; it depends not only on the physical characteristics of the sound such as amplitude and frequency, but also on human perception which can vary among listeners.
Tips
A common mistake is to assume that loudness is only determined by the amplitude of a sound wave, while frequency distribution also plays an important role.
