Fixture for matching microphone capsules
Description
This Is A Fixture I Made To Match Primo Em172 Electret Condenser Microphone Capsules For Sensitivity. The Speaker Is Driven By A Pink Noise Signal And The Mic Capsule Under Test Is Recorded In Audacity, Then A Sample Of The Recording Is Analyzed For The Rms Level. The Mic Capsules Will Be Used To Make A Binaural Mic To Feed My Sony Pcm-M10 Digital Recorder And Some Other Peoples' Projects At The Milwaukee Makerspace.
