Press for that steady subway electrical hum underneath your scene

关于此声音

This is a 2.4-second, 300Hz electrical hum with a constant, low buzzing tone and no voice or music. It feels steady and mechanical, like standing close to powered equipment, with a low tension that makes a scene feel real and lived-in. It is the hum heard inside subway cars, produced by the electrical systems running beneath the carriage.

Let it sit low underneath the whole scene instead of playing it once, so the subway setting stays present without pulling attention away from the action.
