Quizplus · Accepted Answer

A high S/N ratio is desirable in a classroom setting to ensure that speech or lectures are clearly audible and not drowned out by background noise. A range of +10 to +15 dB is considered ideal for a classroom, as it provides a comfortable listening experience without causing ear fatigue or strain. Options A, B, and C do not fall within this range and may result in poor speech intelligibility or difficulty in hearing important information.
