A sound’s perceived warmth depends on specific frequency balance
Evidence
It is curious to note that a sound can be made warmer by either increasing the energy between approximately 200 and 600 Hz or reducing the energy in the 3 to 7 kHz region. Increasing projection approximately in the 2.5 to 4 kHz region relates primarily to voice production and specifically to providing a hint of a singer’s formant (see Section 4.5.2), which has the effect of bringing a singer out toward the front of a mix. — David M.
