Read the following sentence from an academic analysis of early twentieth-century architectural acoustics:
"Although Wallace Sabine's 1900 mathematical model of reverberation time provided architects with their first quantitative tool for evaluating auditorium acoustics, the formula presupposed a completely diffuse sound field—a state seldom achieved in rectangular halls that lack acoustic diffusers or sound-absorbing surface treatments."
True or False: Based on the sentence above, in rectangular halls lacking acoustic diffusers or sound-absorbing surface treatments, Sabine's model relies on a physical condition that is rarely met.
Answer: Answer
Answer
The statement is True.
The statement is True because the target sentence directly pairs the model's assumption ('presupposed a completely diffuse sound field') with the factual observation that this state is 'seldom achieved' in untreated rectangular halls. Therefore, in those specific halls, the model depends on a condition that is rarely present.
