The amplitude of a sound refers to the maximum displacement or variation in air pressure caused by the sound wave. It is a measure of the intensity or loudness of the sound.
Amplitude is typically measured in units such as pascals (Pa) or decibels (dB). However, providing an exact numerical value for the amplitude of a loud sound is challenging since it can vary widely depending on various factors, including the source of the sound, the distance from the source, and the measurement equipment used.
In general, very loud sounds can have high amplitudes. For example, a jet engine at close range or a rock concert can generate sound waves with high amplitudes, potentially reaching several hundred pascals (Pa) or more. However, it's important to note that the perception of loudness is not solely determined by amplitude but also by the frequency content and the characteristics of the human auditory system.
If you are looking for a specific value of amplitude for a particular sound, it would be necessary to provide more specific details about the sound source, the distance, and the context in order to estimate its amplitude accurately.
