In order to calibrate the SPL readings of your Beyerdynamic MM 1 measurement microphone, you need an acoustical calibrator, like the iSEMcon SC-1.

 

However, the MM-1 is an odd duck: It has neither the common ¼" or ½" microphone head diameter, but instead has a “9mm” size - mine is 9.25mm, I assume the datasheet is not very accurate when it comes to this.

 

I modeled an adapter puck which is very much like the SC-1/4" and SC-1/2" but with the “proper” size.

This model is friction fit both on both the inside and outside. Make sure your printer is printing proper size and carefully tweak the model if you are certain. It should stick more to the MM 1 than to the SC-1.

 

My adapter is printed in Prusament PLA Galaxy Black on a Prusa XL with 0.6mm nozzle, IS at 0.15 STRUCTURAL with 15% Gyroid Infill.
