SoundLevelTimeSeries	:	A time series of sound pressure or sound power values. For sound pressure levels, the values are measured in decibels at a reference pressure of 20 microPascals for the referenced octave band frequency. For sound power levels, the values are measured in decibels at a reference power of 1 picowatt(10^(-12) watt) for the referenced octave band frequency.
Frequency	:	The frequency of the sound.
SoundLevelSingleValue	:	A sound pressure or sound power value. For sound pressure levels, the values are measured in decibels at a reference pressure of 20 microPascals for the referenced octave band frequency. For sound power levels, the values are measured in decibels at a reference power of 1 picowatt(10^(-12) watt) for the referenced octave band frequency.
