Room acoustics / modal resonances?

Question

You have a raw space you intend to build into your new studio. After framing and walling in your record room you find it has a 0.0.1 modal resonance of 47 Hz. You decide you want to lower the ceiling by 1 ft. to allow for increased ventilation ductwork. What will be the new frequency of the 0.0.1 modal resonance?

Answer 1

Hi. Not an acoustic engineer but decreasing the volume of an enclosure or room should increase the resonant frequency. Don't have a value for you but it should be tied into the delta change in volume.
