Hi Crossroads,
Thank you so much for your reply.
Regarding your question: "Just curious - what are you using to provide the equivalent of vibrating lips to the brass horns? They need more than just air blowing in don't they?"
I was doing some research on train horns for monster trucks and they seemed to just have tubes connected to air compressors. The type of horns I was thinking of using are old car horns and the one I have for testing doesn't seem to need the same vibrational pressure as a trumpet I have. However, maybe I missing some important considerations for obtaining the correct type of pressure.
Thank you for the suggestions with Hornblasters and considerations on the sensor!
