AI Thread Summary
Sabine's reverberation time equation is not sufficient as the sole design basis for large spaces due to its limitations in accounting for complex sound interactions and the influence of various materials on acoustics. The equation assumes a uniform distribution of sound, which may not apply in irregularly shaped areas. Additionally, it does not consider the effects of audience presence and furniture, which can significantly alter sound behavior. For a comprehensive acoustic design, these factors must be integrated into the planning process. Understanding these limitations is crucial for effective architectural acoustics.

I study architecture and i have an acoustics exam next week. I'm stuck on this question.

Why, on its own, can Sabine's famous reverberation time equation not be the complete design basis for large spaces? give two reasons.

any help would be appreciated.
thanks!

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
