| 描述： | "Viktigt Meddelande för Almänheten (VMA)" is the Swedish alarm test that is done the first Monday in march, June, September and December. It consists of 6 signals each length 7 seconds, then a minute long pause and then a 30 seconds All clear message.This is recorded with my cellphone's headset microphone hung out through my window. This recording is an 8 KHz mono recording, If you listen closely then you can hear a kindergarten nearby and some kids are asking what it is. This sample is recorded at the 6th floor in my apartment with lot of free space around so you can hear the sound reverb around the area. |
