Whispering Gallery Reference
Return the geometric-acoustics mechanism and limitations of whispering-gallery propagation.
Description
Whispering-gallery propagation can concentrate repeated reflections around curved boundaries.
Whispering-gallery propagation can concentrate repeated reflections around curved boundaries. Its strength depends on wavelength, surface and source/listener geometry.1
Return the geometric-acoustics mechanism and limitations of whispering-gallery propagation.
When to use Whispering Gallery Reference
Use this tool to return the geometric-acoustics mechanism and limitations of whispering-gallery propagation.
Choose a supported reference topic, run an input-free reference with an empty object, or prepare the measured values and caller-supplied test records requested. Keep acoustic metrics, frequency, units and test conditions consistent.
How to use Whispering Gallery Reference and understand its results
- Choose a supported reference topic, run an input-free reference with an empty object, or prepare the measured values and caller-supplied test records requested. Keep acoustic metrics, frequency, units and test conditions consistent.
- Enter topic using the field table and calculation rules, then run the tool.
- Read source, statement, topic. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| topic | Reference topic to return. | string; one of "mechanism", "limitation", "mitigation" | Required |
Choose an exact topic enum from the input table and run the lookup. The implementation selects a fixed local entry and returns source, statement and the selected topic. Matching is case-sensitive without trimming or free-text search.
result=stored entry for selected topic Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| source | Source used for the reference statement. | string |
| statement | Narrow reference statement for the selected topic. | string |
| topic | Selected reference topic. | string; one of "mechanism", "limitation", "mitigation" |
{
"input": {
"topic": "mechanism"
},
"output": {
"source": "Geometric acoustics and whispering-gallery literature",
"statement": "Concave circular or elliptical boundaries can guide repeated grazing reflections so sound remains concentrated near the perimeter or between geometric foci.",
"topic": "mechanism"
}
}Limitations and assumptions
No room model, audible effect or treatment effectiveness is calculated. The source is a stored bibliographic label, not a fetched document; statements are not refreshed at runtime.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Parabolic Focus Screen: Calculate the focal distance of a parabolic section from aperture width and depth and screen an occupied location against an explicit focus-zone radius. For a complementary task, use Room Simulation Engine Reference: Compare broad capabilities of established geometric room-acoustics engines without claiming result equivalence.
