Characteristics of Heavy Metal. The main element in heavy metal music is the driving power that the guitar, bass and drums produce through an amplifier. The âheavyâ part is the distortion of the bass and lead guitar. Riffs, solos, sweep-picking and other fast playing tricks all make up what is known as heavy metal.
An amplifier, electronic amplifier or amp is an electronic device that can increase the power of a signal. An amplifier uses electric power from a power supply to increase the amplitude of a signal. The amount of amplification provided by an amplifier is measured by its gain: the ratio of output voltage, current, or power to input. An amplifier is a circuit that has a power gain greater than one. An amplifier can either be a separate piece of equipment or an electrical circuit contained within a
Definition. Amplification- outer ear acts as both a funnel and a resonator. Funnel-the pinna collects sound from a wider area which is directed into the narrower auditory canal. Resonator- the outer ear acts a resonator for sounds within the frequency range of the human voice.
