Correction Function

Windscreen correction function

Corrects the effect on frequency characteristics when a windscreen (WS-10, WS-15, WS-16) is installed to comply with standards.

Diffuse sound field correction function

Correct the effect on frequency response to comply with standards in a diffuse sound field
