What causes higher decibels when crowds make noise (such as in a stadium)?

361 viewsBiologyOther

For example, why isn’t the maximum decibels simply equivalent to the loudest individual person in a group? Is it because everyone is individually being louder or does the amount of people factor in?

Not a sound doctor or anything, but I believe its because the sound waves can synchronize. This increases the amplitude(height/loudness) of the sound wave. Thus making the decibel way higher than a single person could make. If there is a more knowledgeable person, please correct me cuz I’m only like 60% sure this is correct.
