This tutorial session will cover best practices for loudspeaker measurements. It is critical for product development and component selection to know the response of loudspeaker systems and components with reasonable accuracy in order to make informed decisions based on comparisons of data. In this session we will briefly cover the basics of FFT-based measurement systems before moving on to additional topics. Averaging and S/N Windowing (both signal acquisition and impulse response windowing) Ground plane measurement techniques Directivity measurements Maximum input voltage measurements Impedance Alignment of pass bands.
