You&rsquo;re standing on a metro platform, or halfway through a tram ride, and as the train leans into a tight bend the whole carriage erupts into a metallic shriek somewhere between a badly played violin and fingernails on a very large chalkboard. Hands go over ears. Dogs would leave the country. On the worst curves that squeal can reach around 120 decibels right at the rail — loud enough to be a genuine nuisance for passengers, drivers, and anyone unlucky enough to live nearby.</p>
