The effect of ancillary volume on sound transmission measurements using ASTM standard test method E336
Bibliographic record
Abstract
The ASTM Standard E336-05 provides methods to assess the airborne sound isolation between a source and receiving room. In certain field situations, the determination of what constitutes the source or receiving room and its volume may not be obvious. An example is a living room (principal volume) connected to a kitchen (ancillary volume) through an opening in the wall separating the two, and the party wall under test is a surface of the living room (principal volume). Some judgment may be required to define the volume and where the sound field of the "room" should be measured. The Standard requires that the ancillary volume be disregarded if the average sound pressure level in the ancillary volume is 6 or more decibels below the average level in the principal portion of the source or receiving room to which it is coupled at all measurement frequencies. Otherwise, the ancillary volume shall be included as part of the measurement space. This paper investigates the suitability of this criterion.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
