Amplitude reduction refers to the decrease in the strength or intensity of a signal, often observed in various fields such as physics and engineering. This phenomenon can occur due to factors like distance, obstacles, or absorption by materials, leading to a weaker output compared to the original input. In audio and communication systems, amplitude reduction can affect sound quality and clarity. For instance, when a sound wave travels through air, it may lose energy, resulting in a quieter sound at a distance. Understanding amplitude reduction is crucial for optimizing performance in technologies like microphones and speakers.
