C) 62 dBA, of course. Why settle for anything less than the maximum allowable limit? Let's turn that office into a deafening symphony of productivity!

I think the correct answer is 62 dBA because it provides a good balance between noise reduction and cost.

Ah, the old sound masking debate. I say we just install a giant white noise machine and call it a day. That'll drown out the highway noise and give everyone a nice, soothing headache.

I don't know, 48 dBA might be a bit too low. I'd go with D) 70 dBA - that way the noise from the highway won't be a problem, and we can crank up the music to our heart's content!

Hmm, 62 dBA seems a bit high for an open-plan office, doesn't it? I think B) 48 dBA is the way to go for a comfortable working environment.

I agree, 62 dBA does seem high. 48 dBA sounds much more reasonable.
