Audio amplifiers are electric circuits which work to amplify a weak signal, such as the signal from microphones, tape player and several other devices. It amplifies the signal to a level capable of driving a loud speaker.
Some objects that can increase the volume of a sound include speakers, amplifiers, and megaphones. These devices take the audio signal and amplify it to produce a louder output.
The 30 Hz to 30 kHz frequency range is commonly used in audio applications. It covers the audible frequency spectrum for humans, making it suitable for music, speech, and sound reproduction in speakers and headphones. It is also used in various electronic devices such as microphones, amplifiers, and audio processors.
Sound reproduction refers to the process of capturing and recreating sound to replicate the original audio experience. This can involve technologies like microphones, speakers, amplifiers, and audio formats to accurately reproduce sound waves. High-fidelity sound reproduction aims to replicate the original sound as faithfully as possible for listeners.
Sound amplification is created by increasing the energy of an audio signal to make it louder. This is typically achieved using electronic devices like amplifiers, which receive the audio signal and output a stronger signal with greater power. The amplified signal can then be converted back into sound waves through speakers, resulting in a louder sound.
Sound attenuation over distance refers to the decrease in sound intensity as it travels further away from its source. This can affect the quality of audio transmission in communication systems by causing the sound to become quieter and potentially distorted, making it harder to hear and understand. To combat this, communication systems may use amplifiers or other technologies to boost the sound signal and maintain audio quality over long distances.
The definition of audio electronics is the part of science that is dealing with reproducing and recording devices through another device amplifiers.
There are many retailers where one can purchase car audio amplifiers. Edmunds, Best Buy, Amazon, Crutchfield and eBay all sell car audio amplifiers for people to purchase.
Two channel amplifiers, also known as stereo amplifiers. Examples of two channel amplifiers include manufacturers such as Planet Audio, Vibe Audio, MB Quart, Lanzar, Pyrimid and Boss to name a few.
Audio amplifiers are not able to employ others since they are inanimate objects.

Carver Audio company offers many different audio products, ranging from mainly amplifiers, to cassette decks, CD players, tuners, preamps, speakers, etc.
Line6 manufactures electric and acoustic guitars, basses, amplifiers for guitars and basses, effects processors, USB audio interfaces and wireless systems for guitar/bass.
Cap amplifiers can provide an enhanced audio experience as they often are able to reproduce a wider range of audio frequencies compared to many stock car stereos.
Physical vibrations of speaker cones or metal plates by electromagnetic coils connected to the audio output AC signals from the audio amplifiers.
Car amplifiers can be as loud as those which have more than 1000 watt power. The Loudest TL-1021 series from WIKIO are some of the loud car amplifiers. Audio Assault also comes out with car amplifiers of 1000 W.
