Center frequency (Hz)

Effects on music

1/3 octave

 

 

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

31 to 63

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.

 

 

 

Fundamentals of lower tympani. Too much boost produces

80 to 125

excessive "boom". 100 or 125 Hz are also used for hum

 

rejection.

 

 

 

Drum and lower bass. Too much boost produces

160 to 250

excessive "boom". Also useful for 3rd harmonic mains hum

 

rejection.

 

 

315 to 500

Fundamentals of strings and percussion.

 

 

 

Fundamentals and harmonics of strings, keyboards and

630 to 1k

percussion. Boosting the 600 to 1 kHz range can make

 

instruments sound horn-like.

 

 

 

Drums, guitar, accentuation of vocals, strings and bass.

1.25k to 4k

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".

 

 

 

Accentuation of percussion, cymbals and snare drum.

5k to 8k

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.
