So im doing a science fair project for my school and i decided to be different from all the projects. im connecting a 2 channel amp to some old speakers and i was wondering how to measure volume or loudness coming from the speakers when i increase the watts of the amp. my teacher told me theres a specific unit for this and and specific way to measure volume. but so far i cant find much. so i ask you guys for help. please and thanks.
