TREBLE
Music / Electroacoustics The frequencies or PITCHes in a high RANGE, usually undefined as to the specific limits implied. Opposite of BASS. In music it refers to the highest part in a choral piece.
Many amplifiers intended for home use have one control marked 'treble', which alters the GAIN given to higher frequencies. However, such a simple control does little to improve sound QUALITY in any meaningful way, and is more generally used to eliminate HISS on equipment with poor FREQUENCY RESPONSE and SIGNAL-TO-NOISE RATIO. Also called top.
