Sense of power in some outstanding bass singers.
Voice fundamentals.
Important for voice quality.
Important for voice naturalness. Too much boost in the 315 to 1 kHz
range produces a telephone-like quality.
Voice fricatives-accentuation of vocals. Important to speech
intelligibility. Too much boost between 2 and 4 kHz can mask certain
speech sounds e.g. "m", "b", and "v" can become indistinguishable.
Too much boost anywhere between 1 and 4 kHz can produce
"listening fatigue". Vocals can be highlighted by slightly boosting the
vocal at 3 kHz and at the same time slightly dipping the instruments
at the same frequency.
Accentuation of voice. The range from 1.25 to 8 kHz governs the
clarity of voice.
Too much boost causes sibilance.
