Most train horns have more than one leval of sound output,
and some locales have orenances requiring trains to use "soft" levels.
And some just work better than others.
It depends on the type of train and if they are approaching a crossing. Electric trains are much quieter than diesel trains which are quieter than steam trains. Also freight trains and passenger trains sound different. It really does depend on many factors.
Much quieter.
Female what? Female goats with horns are common, Female sheep with horns, not so much, but some breeds do.
Hybrid vehicles in general are much quieter than regular cars. So in that theory, yes, hybrid trucks would be quieter, and take less gas to run as well.
AnswerBison horns curve inward and point at each other. Buffalo horns curve outward. Bull bison horns NEVER point towards each other, only the cow (female) ones do. The words buffalo and Bison (which both literaly translate to "Ox like animal") can both refer to the American Plains Bison (Bison bison bison) and the American Woods Bison (Bison bison athabascae- which is larger). Both species have similar horns. Water buffalo horns are much different.
Trains came much before the telegraphs
They are not necessarily superior. Mag-Lev trains "sway" above the track and therefore they have no friction with anything other than air. Their energy consumption is less efficient and because of the massive concrete or steel track slabs junctions and other track elements are much less efficient and more expensive the traditional rail guided trains.
they normally have 2.
A standard gas generator is generally much quieter than other types of generators. However, a major drawback is the price and cost of installation of a unit.
How much? The good news is you'll run quieter.
