LineSource¶

class acoular.sources.LineSource¶

Bases: PointSource

Class to define a fixed Line source with an arbitrary signal. This can be used in simulations.

The output is being generated via the result() generator.

direction = Tuple((0.0, 0.0, 1.0), desc='Line orientation ')¶

Vector to define the orientation of the line source

length = Float(1, desc='length of the line source')¶

Vector to define the length of the line source in m

num_sources = Int(1)¶

number of monopol sources in the line source

source_strength = CArray(desc='coefficients of the source strength')¶

source strength for every monopole

coherence = Trait('coherent', 'incoherent', desc='coherence mode')¶

coherence

result(num=128)¶

Python generator that yields the output at microphones block-wise.

Parameters:

numinteger, defaults to 128

This parameter defines the size of the blocks to be yielded (i.e. the number of samples per block) .

Returns:

Samples in blocks of shape (num, numchannels).

The last block may be shorter than num.
