Total Harmonic Distortion based on sweep sine exitation for Acoustics

Dear All,

is there a tool to compute the total harmonic distortion based on a swept sine method using the function generator and a microphone input signal? I saw the new sine processing tool for structural dynamics offers the the swept sine THD computation for shakers. Is this also applicable for acoustic measurements of a loudspeaker?

It would be great if an implementation of the THD computation would exist in Dewesoft as an option.

Thank you in advance for your feedback!

Best regards,

Patrick

Dear Patrick,

it is possible to use the Sine processing plugin with loudspeakeer and a microphone. You just need to assign the channel accordingly.

You will be able to compute the THD on response points and obtain transfer functions between reference and response points.
