Sound masking in environments is described as which of the following effects?

• A. Subtly raises the ambient background sound level
• B. Significantly lowers the ambient noise level
• C. Eliminates speech entirely
• D. Increases background noise dramatically

Answer: (A)

Sound masking works by adding a low-level, broadband noise to a space so the overall noise floor is raised just enough to reduce speech intelligibility. The primary effect is a subtle increase in the ambient background sound level, which makes conversations at a distance harder to understand without making the environment feel loud. It isn’t about significantly lowering noise, eliminating speech, or dramatically increasing the noise; it’s a controlled, barely noticeable rise in background level that enhances privacy and comfort.
