Here are a few clarifications:
1. Perceived loudness: The perception of loudness is subjective and can be influenced by multiple factors, including the listener's preferences, the listening environment, the sound system, and the vocal technique used by the singer.
2. Different styles: Different genres and musical styles may emphasize different aspects of a singer's voice, and what may be considered loud or powerful in one genre might not be so in another.
3. Vocal range and projection: Some singers may have impressive vocal ranges or high-pitched notes, while others may have strong projection that allows their voices to be heard clearly in larger venues.
4. Technique and artistry: Loudness is not necessarily an indication of vocal quality or artistry. Many great vocalists are known for their range of dynamics, their expressiveness, and their unique interpretations, rather than their sheer volume.
Overall, it is challenging to objectively determine who has the loudest voice. It is more appropriate to appreciate and enjoy the unique talents and vocal abilities of different singers rather than focusing on a singular aspect like volume.
