Reverberation decay time, often referred to as RT60, represents the duration required for sound pressure level to decrease by 60 decibels after the sound source ceases. Accurate determination of this parameter is essential in acoustics to characterize room response and suitability for various purposes. It is calculated using specialized equipment or software that measures sound pressure levels over time and analyzes the decay curve.
Precisely determining reverberation characteristics provides multiple benefits. It informs acoustic design and treatment decisions, leading to optimized listening environments for music performance, recording, speech intelligibility, and general comfort. Historically, assessments were subjective, relying on human perception. Modern measurement techniques offer objective and repeatable results, allowing for scientific comparison and validation of acoustic treatments.
