Question

Unit of sound absorption is

• A. Sone
• B. Decibel
• C. Hertz
• D. Sabin

Hint:

In acoustics, remember that Sabins are used to quantify how much sound a material absorbs, which is crucial for designing spaces with good sound quality.

Answer 1

The Correct Option is D

Step 1: Understanding sound absorption.
The unit of sound absorption is the Sabin, which measures the effectiveness of a material in absorbing sound. It is used to quantify how much sound energy a surface absorbs, and it is especially important in acoustics.

Step 2: Analyzing the options.
(A) Sone: The sone is a unit of perceived loudness, not sound absorption.
(B) Decibel: Decibels measure sound intensity, but they do not specifically quantify sound absorption.
(C) Hertz: Hertz measures frequency, not sound absorption.
(D) Sabin: Correct — Sabin is the correct unit used to measure sound absorption.

Step 3: Conclusion.
The correct answer is (D) Sabin, as it is the unit of sound absorption.
