Final answer:
Baffles are sometimes forbidden due to unwanted reflections, safety concerns, or regulatory requirements.
Step-by-step explanation:
The use of baffles is sometimes forbidden because they can create unwanted reflections or echoes, interfering with the intended sound or signal.
Baffles are used to redirect or control the flow of sound or waves, but in certain situations, they may cause undesirable effects.
For example, in a concert hall, baffles are strategically placed to enhance the acoustics and distribute sound evenly.
However, if the baffles are not properly positioned or designed, they can create echo or reverberation problems.
In other cases, the use of baffles may be restricted due to safety concerns or to meet specific regulations, such as in industrial environments where certain types of baffles may impede the flow of air or pose a hazard.
