Important for voice quality.

630 to 1k

Important for voice naturalness. Too much boost in the 315 to 1 kHz
range produces a telephone-like quality.

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.

5k to 8k

Accentuation of voice. The range from 1.25 to 8 kHz governs the
clarity of voice.

10k to 16k

Too much boost causes sibilance.
