2-8 A concert hall is under construction. At the present stage of con- struction, the walls are bare and the hall is empty. It is 10 m high, 30 m wide and 40 m long. A loudspeaker connected to an audio oscil- lator and amplifier is set up in the hall. The acoustic engineer knows that with the apparatus turned on, acoustic resonances (standing waves) will occur in the room at certain frequencies. Calculate the three fundamental frequencies of the resonances that the engineer should expect. 2-8 A concert hall is under construction.
