Why do I always hear remote train horn at night?

$\begingroup$

There are two things that can be considered: one is trivial – that it is quieter at night so you are more likely to hear the horn.

The second is physics: the speed of sound depends on the square root of temperature, so the refractive index is proportional to $T^{-1/2}$.

At night it is quite possible to get a temperature inversion, such that air near the ground is colder than higher up. This would normally occur in still conditions and I think is more common in winter.

As the refractive index decreases with height it means that sound waves propagating upwards at some angle to the horizontal will be bent back towards the ground. The sound waves at some distance from the source will be more intense than you might expect if the waves propagated isotropically.

The contrast with the daytime situation would be enhanced by a more normal temperature gradient where the refractive index increases with height.

EDIT: For an excellent visualisation of this effect, see these animations produced by Daniel Russell (Penn State)

STORY!

After the Ice Storm in 1998 (we were on the southern end – thousands of power poles down, tree damage, etc), my fire department developed a close relationship with one of the dozen fire departments sent into the area to help us out. In the years since our members have gone to visit them for their field days and other events, and their members have been up for golf, dinners, barbeques, etc.

We frequently camp on their field day grounds when we visit – sometimes a small tent city. Evenings around the campfire usually involve some spirits of the liquid kind, in some cases to a certain level of excess.

You have to cross the old Erie line (Port Jervis to Binghampton – now NYSW/NS) to get onto the grounds. There is also a very sharp curve, a bridge (over the Delaware) and 4-5 crossings in a very short space. Makes for a rather noisy visit.

One Sunday morning, just after sunrise (and not all that long after we’d called it a night), one of our members (who’d spent a lot of time with Jack D that evening) was rudely awakened by what he swore was a train coming through his tent.

I was too busy scrambling out of my tent for a better view to even notice.
