الملخص	The Room Impulse Response (RIR) is a measure of how a physical space (room) affects acoustic signals propagating through it. First formalized by Manfred Schroeder in 1965, RIR captures the complete acoustic character of a space by measuring the system response to an impulsive sound source. It is fundamental to characterizing room acoustics, designing audio systems, and modeling spatial audio effects.	RT60 (reverberation time) is the duration required for sound energy in a room to decay by 60 decibels after the source stops. Pioneered by Wallace Clement Sabine in 1900, RT60 is the most widely used single-number descriptor of room acoustic properties. It reflects how much sound is absorbed versus reflected by room surfaces and directly affects speech intelligibility, music clarity, and acoustic comfort.
