From a scientific perspective, definitely, but we also have to think about what can actually be done.
I think overall exposure to noise and daytime exposure to noise are maybe more in the domain of urban planning, zoning, sound insulation, and making sure that we don't expose more people—for example, that we don't build buildings right next to airports if we can avoid it.
With the nighttime noise, if you could snap your fingers and have no more planes after 11 at night or before seven in the morning, that problem would be gone, even if you have people living next to the airport.
I would definitely separate those out.
