displacement
(v, omega)[source]¶ Particle displacement.
\[d(x, t) = \int_{-\infty}^t v(x, \tau) d\tau\]

synthesize
(d, weights, ssd, secondary_source_function, **kwargs)[source]¶ Compute sound field for a generic driving function.
Parameters: d (array_like) – Driving function.
weights (array_like) – Additional weights applied during integration, e.g. source selection and tapering.
ssd (sequence of between 1 and 3 array_like objects) – Positions, normal vectors and weights of secondary sources. A
SecondarySourceDistribution
can also be used.secondary_source_function (callable) – A function that generates the sound field of a secondary source. This signature is expected:
secondary_source_function( position, normal_vector, weight, driving_function_weight, **kwargs) -> numpy.ndarray
**kwargs – All keyword arguments are forwarded to secondary_source_function. This is typically used to pass the grid argument.
