Why do school buses smell so bad?
Why do school buses smell so bad? Diesel engines, which are commonly used in trains and buses, release a combination of gases and particulates into the air. These emissions include nitrogen oxides (NOx), sulfur dioxide (SO2), and particulate matter (PM), which can produce a strong, acrid smell.
Why do buses rattle so much?
Besides road debris, much of the noise you hear inside a bus is rattling from the metal panels that vibrate and shake as you drive along. To reduce this clanging, you can deaden the metal, which will reduce the vibrations - and you can't have structural sound without vibrations.
