Hola!!!! I can assure you that this did not happen at the Stupa. Ceremonies are held at the Stupa on Sunday mornings and on Wednesdays from 4:30 to 5:30 PM. Once a month, during the full moon, there is an evening ceremony, but it ends by 8:00 PM at the latest. We do not use any type of loudspeaker or amplified sound system, so the sound does not travel far. Therefore, it is very unlikely that any noise heard at a distance originated from the Stupa.
