Introduction of the Instruments, the technical details with some basic measurements


Introduction:

The performance that will be presented in Los Angeles on September 6, 2012 is based on the research works of scientist Royal R. Rife and his legacy. Starting from 1934, he experimented with audio frequency instruments in the La Jolla Clinic. He used them to tune to the vibration frequencies of certain viruses and bacterial diseases, and to kill them by applying corresponding electronic vibration to the living tissue. 
For this performance I have designed a home-made sound transmitter, which allows the sound coming from a digital oscillator to spread in space before it is modulated. This instrument may produce output interference (feedback). Hence, I have built a lead cage (a sort of Faraday cage), which can shield the audio frequencies existing in the exhibition space. By changing the sensitivity of the microphone built into the cage, the feedback can appear in the final output. The sound structure can also be modified with a frequency filter forming the last link in the chain. The choreography is based on systematic connections, which are modified by any change in one of these parts, and thus determines the texture of the sound.

Measurements with Sound Level Meter:

1.
Location: Samorín, Slovak Republic 
Time: 11:16pm
Unit: CEC DT-805
Sound level average Ranges from 30dB to 130dB at frequencies between 31.5Hz and 8kHz.

Measurements on slow response (time weighting) (for checking average level of fluctuating noise) the level range was on a hight frequency mode which is measure the 60130dB range.
A -Weighting. For general sound level measurements.
Data hold button: on
Final measurement: 59,0dB

2.
Time: 11:18pm
Unit: CEC DT-805
Sound level average Ranges from 30dB to 130dB at frequencies between 31.5Hz and 8kHz.

Measurements on slow response (time weighting) (for checking average level of fluctuating noise) the level range was on a low frequency mode which is measure the 30100dB range.
A -Weighting. For general sound level measurements.
Data hold button: on
Final measurement: 40,6dB

3.
Time: 11:48pm
Unit: CEC DT-805
Sound level average Ranges from 30dB to 130dB at frequencies between 31.5Hz and 8kHz.

Measurements on slow response (time weighting) (for checking average level of fluctuating noise) the level range was on a low frequency mode which is measure the 30100dB range.
C -Weighting. For checking the low-frequency content of noise.
(If the C -Weighted level is much higher than the A -Weighted level, than there is a large amount of low-frequency noise.)
Data hold button: on
Final measurement: 50.7dB

4.
Time: 11:48pm
Unit: CEC DT-805
Sound level average Ranges from 30dB to 130dB at frequencies between 31.5Hz and 8kHz.

Measurements on slow response (time weighting) (for checking average level of fluctuating noise) the level range was on a low frequency mode which is measure the 30100dB range.
C -Weighting. For checking the low-frequency content of noise.
(If the C -Weighted level is much higher than the A -Weighted level, than there is a large amount of low-frequency noise.)
Data hold button: off
Final measurement: 46.3dB

Instruments:

Two instruments together with the cage.

 















The old instrument with the new glass tube shielded transmitter.

















Frequency shield for the old instrument (Faraday cage) The lead is cover radio and electromagnetic fields also it may shield some audio frequencies. My transmitter operates on the middle range frequencies. The cage may will also cover that field.
