It is an old otis brand elevator, in a 10-story building. You can see that the elevator motor is so old that it was manufactured with relay contacts and not with an electronic board.
Riding in building elevator during a trip to visit rrr in lowell. 0:18 - close mic elevator fan noise with weird ringing sound; 0:30 - drumming on elevator interior; 0:45ish - elevator doors opening and closing. 0:55 - "good day!".
