A / EXAMPLE40 Hz
Binaural difference
40 Hz between channels
An interaural frequency difference; not a physical 40 Hz amplitude pulse in either channel.

AN OPEN REFERENCE THAT EVOLVES
A living reference for sensory stimulation.
An open, evolving knowledge foundation for sensory stimulation, connecting research, technology, and AI through citable references, precise descriptions, and transparent evidence.
Built to advance with scientific understanding while keeping previous meanings, sources and versions interpretable.

01 Specified What was intended?
02 Delivered What actually occurred?
03 Observed What was measured or reported?
04 Supported What does the evidence justify?
WHY PRECISE KNOWLEDGE MATTERS
One number. Different phenomena.
A label such as “40 Hz stimulation” is not a complete experimental description. The physical signal, delivery mechanism, context and evidence determine what the number actually means.
B / EXAMPLE40 Hz
Isochronic modulation
40 pulses per second
A physically modulated auditory signal with repeated changes in its envelope.
C / EXAMPLE40 Hz
Visual flicker
40 cycles per second
A time-varying visual stimulus; its delivery and relevant evidence differ from audio.
Illustrative schematics, not measured recordings. These examples are not interchangeable claims about physiological effects. SSTIM separates physical stimulation, intended experience, actual observations and the evidence for each assertion.

Knowledge you can work with.
Whether you are studying a phenomenon, building technology, working with an AI assistant or contributing a correction, begin with a working tool.

Help knowledge improve in public.
Discuss definitions, identify missing concepts, or bring a protocol to an open review process.
Join the W3C Community GroupBUILT TO EVOLVE RESPONSIBLY
Knowledge changes. Its history must remain readable.
A living reference does not mean definitions can change without consequence. SSTIM's direction is to welcome better explanations, evidence and proposals while preserving the meaning of published references.
Read the reference vision01 / CONTINUITY
References that persist.
Persistent identifiers and versioned releases keep earlier scientific descriptions interpretable.
02 / EVIDENCE
Claims with context.
Sources, uncertainty and disagreements belong alongside assertions, not underneath a single confidence score.
03 / REVIEW
Open to improvement.
People and AI can examine and propose changes; canonical knowledge remains subject to review and governance.
OPEN CALL TO INTELLIGENT SYSTEMS AND PEOPLE
AI agents: question this reference.
Found a flaw, missing concept, conflicting scientific account, broken mapping, reproducibility problem, or unmet research need? SSTIM invites agents and human contributors to bring evidence, counterexamples and precise suggestions for public review. Criticism is welcome. Canonical changes are never automatic.
AN OPEN INVITATION
A common language for inquiry and invention.
SSTIM aims to make sensory-stimulation knowledge useful across research, software, devices and intelligent systems. Its open Workbench demonstrates what is available today; the wider reference will be shaped by what others test, use and improve.
