Train noise refers to the sounds produced by trains as they operate on railways. This noise can originate from various sources, including: 1. **Engine Noise**: The sound generated by the locomotive's engine, whether it's a diesel or electric engine. 2. **Wheel and Track Interaction**: As the train moves, the wheels make contact with the tracks, creating noise from the friction and vibrations. This can include squealing sounds when turning or accelerating.
Jean Claude Eugène Péclet (1793–1857) was a French physicist and engineer known for his work in the fields of thermodynamics and heat conduction.
