Sound Production and Manipulation [SPM]  ]

The process of producing an increase in the energy of a sound or an audio signal. This may be accomplished by means of an electronic amplifier or by means of an acoustic resonator, such as the sound box of a musical instrument, an ear-trumpet, etc. Attaching (i.e. coupling) a vibrating object to another surface, such as a soundboard, wall or floor, will result in a more efficient transfer of energy, and hence this process may also be termed amplification. Amplification or gain may be measured in decibels. (Source: Barry Truax - Handbook for Acoustic Ecology CD-ROM Edition. Cambridge Street Publishing, 1999 - CSR-CDR 9901)
