radia # 685 SENSATHESIA
- a work born from the imagination of the Itinerary of Radio TCR 10.1 from TEA FM Radio School based on an original idea from Laura Sierra and Stel Garcia.
Sensation is the body's detection of external or internal stimulation (e.g., eyes detecting light waves, ears detecting sound waves). Perception utilizes the brain to make sense of the stimulation (e.g., seeing a chair, hearing a guitar).
Sensation involves three steps:
• Sensory receptors detect stimuli.
• Sensory stimuli are transduced into electrical impulses (action potentials) to be decoded by the brain.
• Electrical impulses move along neural pathways to specific parts of the brain wherein the impulses are decoded into useful information (perception).
For example, when touched by a soft feather, mechanoreceptors – which are sensory receptors in the skin – register that the skin has been touched. That sensory information is then turned into neural information through a process called transduction. Next, the neural information travels down neural pathways to the appropriate part of the brain, wherein the sensations are perceived as the touch of a feather.
Children are often taught five basic senses: seeing (i.e., vision), hearing (i.e., audition), tasting (i.e., gustation), smelling (i.e., olfaction), and touching. However, there are actually many more senses including vestibular sense, kinesthetic sense, sense of thirst, sense of hunger, and cutaneous sense.
Synesthesia is a neurological condition in which stimulation of one sensory or cognitive pathway (e.g., hearing) leads to automatic, involuntary experiences in a second sensory or cognitive pathway (e.g., vision). Simply put, when one sense is activated, another unrelated sense is activated at the same time. This may, for instance, take the form of hearing music and simultaneously sensing the sound as swirls or patterns of color. Since synesthesia can involve any combination of the senses, there may be as many as 60 to 80 or subtypes, but not all have been documented or studied, and the cause is unclear.
The most commonly seen type is grapheme-color synesthesia, in which individual letters and numbers are associated with specific colors and sometimes colorful patterns. Some synesthetes perceive texture in response to sight, hear sounds in response to smells, or associate shapes with flavors.
Many synesthetes have more than one type of synesthesia. It is estimated that approximately 3 to 5 percent of the population has some form of synesthesia, and the condition can run in families.
How can we explain the result if you mix sensation and synesthesia with the human sound perception?
We call it Sensathesia.
DIE ZWEITE HÄLFTE
Oramic Radio Sounds by TEA FM
RADIA # 358
The School of Creative Radio TEA FM from Zaragoza has developed a new radio documentary based on the works and sounds made by Daphne Oram (Dec 31th 1923 – Jan 5th 2003) British composer and electronic musician. She was the creator of the “Oramics” technique for creating electronic sounds.
Developed in documentary form, we will cross the sounds created by her “Oramics Machine” and we will talk with people close to her and her work.
In 1959 she installed her Oramics Studios for Electronic Composition in Tower Folly, a converted oast house at Fairseat, near Wrotham, Kent. Her output from the studio, mostly commercial, covered a far wider range than the Radiophonic Workshop, providing background music for not only radio and television but also theatre and short commercial films. She was also commissioned to provide sounds for installations and exhibitions. Other work from this studio included electronic sounds for Jack Clayton’s 1961 horror film The Innocents, concert works including Four Aspects and collaborations with opera composer Thea Musgrave and Ivor Walsworth.
With the voice and talent of:
Isabel Aparicio, Daniel Canelo, Mar Gonzalez, Manuel Alcaine, Miguel Deza, Reyes Casasnovas and Carlos Berdiel
Music & FX:
Daphne Oram, TEA FM FX gallery, BBC and MEC Sound Archive
Script and production:
A TEA FM production. Recorded on TEA FM-CTA Studios on January 2012.
