Space Noise Criteria Reference
Return room-noise criterion selection cautions for occupied spaces.
Description
Room-noise criteria relate background sound to occupancy and communication needs.
Room-noise criteria relate background sound to occupancy and communication needs. Spectral information can reveal features hidden by a single overall level.1
Return room-noise criterion selection cautions for occupied spaces.
When to use Space Noise Criteria Reference
Use this tool to return room-noise criterion selection cautions for occupied spaces.
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 Space Noise Criteria 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 "selection", "spectrum", "caution" | 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 "selection", "spectrum", "caution" |
{
"input": {
"topic": "selection"
},
"output": {
"source": "ASHRAE Handbook—HVAC Applications",
"statement": "Background-noise criteria depend on occupancy, communication needs, concentration, sleep, privacy, and the specified rating method.",
"topic": "selection"
}
}Limitations and assumptions
No project target, legal limit or measured compliance is determined. 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 Room Criterion Reference: Distinguish RC-family ratings and diagnostic descriptors without reproducing proprietary or edition-specific tables. For a complementary task, use Practice-Room Noise Target Screen: Compare a measured room-criterion value with an explicit caller target while preserving the caller’s instrument-family label.
