.. _exampleNoiseSourceDistribution:

Computing noise source distributions
====================================

This example shows how to plot noise source distributions at a specific time step of an existing trajectory. 

.. code-block:: python

	import os
	import pdb
	import numpy as np
	import openmdao.api as om
	import pandas as pd
	import matplotlib.pyplot as plt

	os.environ["pyna_language"] = 'python'
	from pyNA.pyna import pyna

	# Load default pyna settings
	pyna_settings = pyna.load_settings(case_name = 'nasa_stca_standard')
	pyna_settings.save_results = True

	# Run pyna
	py = pyna(settings=pyna_settings)
	py.settings.validation=False

	# Plot results
	py.plot_noise_source_distribution(time_step=152, metric='spl', components=['core', 'jet_mixing', 'airframe', 'fan_inlet', 'fan_discharge'])
