質問 # 120
Ambient noise PRIMARILY affects desired sound by
- A. interfering with it.
- B. enhancing it.
- C. complementing it.
- D. canceling it out.
正解：A
解説：
Comprehensive Detailed Explanation with all Technology Specialist References:Ambient noise is any unwanted background sound that can interfere with the clarity and intelligibility of the desired audio signal. In an AV setting, ambient noise can reduce speech intelligibility, making it harder for the audience to understand the speaker or experience the audio as intended.
Option B, "canceling it out," would refer to techniques like active noise cancellation, which isn't the primary effect of ambient noise on sound but rather a solution to it. Options A and D, "enhancing" and
"complementing," are not applicable because ambient noise typically detracts from audio quality rather than adding to it.
