I don't think about the things that I know
"BANG!" - an Open Letter
Supressed Noise This Early experiment, based on percepts contained in the
Spridgeon volume of the same name, provides the listener with an audible example of what
he means by "The Voice used as an instrument od electro-acoustic investigation."
This piece is also one of the earliest processing of 'Display' information
projects undertaken by The Hafler Trio.
Inherent Agression: The following section of material demonstrates the Hafler
system of ergonomics as applied to evaluation of sensor response - and it's
somewhat unexpected results!
All Largely Propaganda: The piece demonstrated on martin Gunther's 'Today' programme
as an immediate illustration of his explanations of the sound/colour relationship experiments
underway at the time, when Dr. Moolenbeek was invited to appear as a guest on the programme. It was felt by all concerned that this exposition of the technique was worthy of a wider hearing.
A Sound & Colour Analogy In tandem with the preceding piece, this experiment result from the same seminar as resulted in Spridgeon's works receiving their recent revival, highlighted the urgent need of addressing the relevant 'field' questions within the frame of reference at the correct stage of the process. This simulation of the impromptu demonstration given is recreated faithfully by the original participants in the studio.
Acoustic Lens Facsimile Unfortunately, the assignation of the acoustic lens spectrum properties to specific functions varies considerably throughout the experimental world. This working model for the acoustic lens, never hitherto attempted in practice before, shows that the researchers who say that this construction is impossible, are mistaken.
"Bang!" The piece speaks for itself, save to remind the listener that its origin lies in the now famous open letter from Spridgeon to Moolenbeek. The temporal reference characteristic appears at the end of the section.
The Morality Of Sound "... Rather, it is their combined function that determines the quality of the result", said Spridgeon in the book of the same name. This piece is a combination of these ideas and also includes an interesting example of aural decodation testing.
The Location Of Detached Sounds Feedback loop impression traits have always been of interest to The Hafler Trio. Here the technical factors are all taken into consideration at once to provide a comprehensive picture of this phenomenon.
Plychophon Installation Test Tape Specially designed by The Hafler Trio with the capital projects department of ROBOL in mind. When 'On Site', carrying out work of this kind is greatly assisted by lining up this tape to the recommended levels, which then brings the rest of the specifications needed into synchronisation.
Location Screening Exercise Many of these experiments are carried out by The Hafler Trio for ROBOL's private commissions. Enclosed here is one example of this particular approach.
The Limitatians Of Silence This condensed selection from the hours of available material highlights the problems and the rewards of research in this area and related fields. Thankfully, the analytic procedures devised in accordance with the guidelines laid down at the 1967 symposium at the Douglas Advanced Research Laboratories are flexible enough to allow this example to be included here.
Echoes In The Body This highly complex field, first investigated again by Spridgeon, yields the many fascinating results such as this examination of the invariance principles due to flux during the original installation of the diode phase comparison equipment in the Atomium, Brussels, for the World's Fair 1958, developed by ROBOL.
"Robolised" Atomium Dawn Chorus A truly striking example of this exciting new technique.
A Demonstration Of The Non-Medical Use Of Microphones Once more, based on the original proposals for research by Robert Spridgeon, founder of ROBOL. Until very recently, the specialised precautions which brought the scorn from authorities and colleagues alike, when originally formulated, were absolutely necessary. Now we are able, thanks to new findings and developments, to release recordings utilising these techniques and methods to a wider circle.
Owl Ionisation Recording (1968) Perhaps the most famous of all the last recordings made by Spridgeon himself for ROBOL. We include this one here by kind permission of his estate.
