Seat Absorption Delta
Calculate the signed occupied-minus-empty equivalent absorption for a seating sample and per seat.
Description
Seating absorption can change with occupancy.
Seating absorption can change with occupancy. A measured sample difference should retain its frequency and test context separately.1
Calculate the signed occupied-minus-empty equivalent absorption for a seating sample and per seat.
When to use Seat Absorption Delta
Use this tool to calculate the signed occupied-minus-empty equivalent absorption for a seating sample and per seat.
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 Seat Absorption Delta 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 emptyEquivalentAbsorptionSquareMeters, occupiedEquivalentAbsorptionSquareMeters, seatCount using the field table and calculation rules, then run the tool.
- Read totalDeltaSquareMeters, deltaPerSeatSquareMeters. 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 |
|---|---|---|---|
| emptyEquivalentAbsorptionSquareMeters | Empty-seat equivalent absorption (m²) | number; minimum: 0 | Required |
| occupiedEquivalentAbsorptionSquareMeters | Occupied-seat equivalent absorption (m²) | number; minimum: 0 | Required |
| seatCount | Seat count | integer; minimum: 1 | Required |
Enter finite nonnegative equivalent absorption in m² and positive safe-integer seats. Return signed total/per-seat difference.
delta=occupied−empty; perSeat=delta/count Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| totalDeltaSquareMeters | Total occupied-minus-empty delta (m²) | number |
| deltaPerSeatSquareMeters | Delta per seat (m²/seat) | number |

}Limitations and assumptions
Negative differences are preserved. No absorption is measured or transferred universally to other seating, bands or occupancy conditions.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
