Sound amplification

Sound amplification is the process of increasing the volume of sound so it can be heard more clearly, especially over distance or in noisy environments. It typically involves a microphone that captures sound waves and converts them into electrical signals. These signals are then boosted using an amplifier, which increases their power. Finally, a speaker converts the boosted signals back into sound waves at a higher volume. This process is used in various devices like public address systems, microphones, and hearing aids to make sounds clearer and more audible.
