APPENDIX Q- SOUND LEVEL DATA


Summary of Calculated Values.

Q1.

D BA B UMPS

These data are used to describe sound level measurements for various frequencies that exceed the levels of their immediate neighbors by the variances shown below. Items that equal or exceed the variance are identified with the value of 1 otherwise they contain the value of zero.

Description Field Name Columns

1/1 octave band, 4dB variance

See SPL_C in raw data (Float)

Q3.

D BC D BA

Use SPL_C - SPL_A in raw data (Float)

Q4.

NC – N OISE C RITERIA

NC selects the highest measured sound level that fits within a standardized sound level.

NCMax stores the maximum sound level found. (Float)

NCFreq stores the frequency where this sound level was found. (Integer)

Q5.

NCB – B ALANCED N OISE C RITERIA

NCB is one method to determine if rumble and hiss exist in a sound sample.

SIL stores the Sound Interface Level used to select the NCB reference level for rumble (Float)

NCBRumble stores a 1 if rumble is detected otherwise a 0 (Integer)

NCBRefHiss stores the NCB reference level for hiss (Integer)

NCBHiss stores a 1 if hiss is detected otherwise 0 (Integer)

Q6.

RC – R

OOM

C

RITERIA

RC stores the RC table level that is used for analyzing hiss and rumble (Float)

RCRumble stores a 1 if rumble is detected otherwise a 0 (Integer)

RCHiss stores a 1 if hiss is detected otherwise a 0 (Integer)

Q7.

RC M ARK II (RCII) A LTERNATE R OOM CRITERIA

RCII is another derivative that analyzes rumble, hiss and an intermediate quality descriptor named roar.

RCII stores the RC table level that is used for analyzing hiss, rumble and roar (Integer)

DeltaLF stores a cumulative difference between the table and the measured low freq values (Float)

DeltaMF stores a cumulative difference between the table and the measured med freq values (Float)

DeltaHF stores a cumulative difference between the table and the measured high freq values (Float)

RCIIQual stores the indicator for the highest Delta, 0=none, 1=LF, 2=MF, 3=HF, whenever DeltaMax is greater than 5 (Integer)

DeltaMax (QAI) stores the largest difference between any pair of Deltas above (Float)
