magnograil,
Excellent idea! I'll use a H-Q tube with an expansion chamber inline. That should save a lot of space. Do you have any idea where I can obtain the relevant equations for simple modeling of this setup (ball park estimates of tube size/length, I'll tweak it during field tests). The...
Rob45,
What is the consequence of using a Helmholtz resonator that doesn't fit the sizing criteria (frequency*volume>20,000). I am designing a side branch necked Helmholtz resonator for an auto exhaust system and space contraints force me to use a resonator size ~8000 (120Hz*66in3). I am...
