Quantities and units

The Quantity module provides two classes to work with quantities and units.

class acoustics.quantity.Quantity(name, unit, dynamic, symbol=None, symbol_latex=None, reference=1.0)

Quantity.

__init__(name, unit, dynamic, symbol=None, symbol_latex=None, reference=1.0)

Initialize self. See help(type(self)) for accurate signature.

dynamic = None

Dynamic quantity (True) or energetic (False).

energetic

Energetic quantity (True) or dynamic (False).

name = None

Name of the quantity.

reference = None

Reference value of the quantity.

symbol = None

Symbol of the quantity.

symbol_latex = None

Symbol of the unit in LaTeX.

unit = None

Unit. See Unit.

class acoustics.quantity.Unit(name, symbol, symbol_latex)

Unit of quantity.

Note

Perhaps inherit from tuple or collections.namedTuple?

__init__(name, symbol, symbol_latex)

Initialize self. See help(type(self)) for accurate signature.

name = None

Name of the unit.

symbol = None

Symbol of the unit.

symbol_latex = None

Symbol of the unit in LaTeX.

acoustics.quantity.get_quantity(name)

Get quantity by name. Returns instance of Quantity.

Parameters:name – Name of the quantity.

acoustics.quantity.quantities = {'pressure': ('Pressure', 'pascal', True, 'p', '$p$', 2e-05)}

Dictionary with quantities. Each quantity is stored as a tuple.

acoustics.quantity.units = {'meter': ('meter', 'm', '$m$'), 'pascal': ('pascal', 'Pa', '$Pa$')}

Dictionary with units. Each unit is stored as a tuple.
