# 3 // 50 years in june in a space of 9 days (2001)
We experience sound with extremly low frequence as a rythm, not as a tone. The human ear begins to hear tones at 16 cycles/second. It´s easy to imagine the sound of a clock. It´s ticking. I can imagine the ticking as a sound that follows you all the time. Not as a ticking sound per se, but as a long, long expanding sound with a frequence of 1 cycle/second. (In my case, the length of this sound is about 36 years by now.)A sound with a length of 50 years and a frequency of 1 cycle/second, gets a frequency of 2375,75 hz if you squeeze it into a space of 9 days. Connect a tone-generator to a loudspeaker. Place the loudspeaker in a room that you can spare for 9 days. Seal the room. Set the tone-generator to 2375,75 hz/sec and turn it on. After 9 days, turn it off. With other times, use this formula: (60 x 60 x 24 x 365,25 x year) / (60 x 60 x 24 x days) = hz
