Strange Acoustical Resonances Gives Current Subway Cars an R9 Bearing Whine Sound at Union Square |

Posted by heypaul on Sat Mar 23 13:44:36 2019 In the last couple of weeks I noticed two R160's sound like an R9 when accelerating and braking at 14 St Union Square. I thought it weird. Yesterday I was at Union Square, protesting the war in Viet Nam. On my way home, I heard the sounds again and recorded them. Standing on the downtown platform, the sounds are most noticeable when an uptown express or downtown local pulls in. Is there some sort of resonance in the station that gives this effect?Bearing Whine |
