Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the unit of measurement?Sound absorption
2. What is the conceptual originator?Wallace Clement Sabine, using the 'open-window unit'
3. What is a sabin?A sabin is a unit that measures how much sound a surface can absorb. It tells us how much sound energy is taken away when it hits a wall, floor, or other surface.
4. Who created the sabin?Wallace Clement Sabine invented it in the late 1890s while studying sound in Harvard’s lecture hall. He called it the "open-window unit" before it was renamed the sabin.

Sound Absorption Coefficient (α): A dimensionless value (0 to 1) representing the proportion of incident sound energy absorbed by a material.
Reverberation Time (RT60): The time required for sound pressure level to decrease by 60 decibels after the sound source stops.
Architectural Acoustics: The science concerned with the control of sound within buildings and other structures.
Empirical Measurement: Knowledge gained through observation and experimentation rather than theory alone.
