31 to 63

Fundamentals of bass drum, tuba, double bass and organ. These frequencies

give music a sense of power. If over-emphasised they make the music

"muddy". The 50 or 60 Hz band is also used to reject AC mains hum.

80 to 125

Fundamentals of lower tympani. Too much boost produces excessive "boom".

100 or 125 Hz are also used for hum rejection.

160 to 250

Drum and lower bass. Too much boost produces excessive "boom". Also

useful for 3rd harmonic mains hum rejection.

315 to 500 Fundamentals of strings and percussion.

630 to 1k

Fundamentals and harmonics of strings, keyboards and percussion. Boosting

the 600 to 1 kHz range can make instruments sound horn-like.

1.25k to 4k

Drums, guitar, accentuation of vocals, strings and bass. Too much boost in

the 1 to 2 kHz range can make instuments sound tinny. Too much boost

anywhere between 1 to 4 kHz can produce "listening fatigue".

5k to 8k

Accentuation of percussion, cymbals and snare drum. Reduction at 5 kHz

makes overall sound more distant and transparent. Reduction of tape hiss

and system noise. The 1.25 to 8 kHz governs clarity and definition.

10k to 16k

Cymbals and overall brightness. Too much boost causes sibilance. Reduction

of tape hiss and system noise.

40 to 125 Sense of power in some outstanding bass singers.

160 to 250 Voice fundamentals.

315 to 500 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.

1.25k to 4k

Voice fricatives-accentuation of vocals. Important for 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.
