Impulse, Reflection, Decay: Why Acoustic Engineers Still Trust the Time Domain Over Frequency Specs
Frequency-domain specifications paint an incomplete picture of how a room or loudspeaker truly behaves. Impulse response measurement remains the definitive tool for acoustic engineers designing everything from Carnegie Hall to home theater installations, revealing the temporal structure of sound that flat frequency plots routinely conceal. This guide traces the method from its analog origins through modern swept-sine acquisition and explains how to interpret the data that matters.
