I am so happy you liked it. In order to open the door you need pay close attention to the intervals between each signal emitted by each of the three resonators. See solution bellow:

SPOILER:
You need to match your frequency and number of your emitted signals to the ones of each resonator one by one. For example the resonator in the lower left part of the room emits four signals in every 1.2 seconds. In order to disable that resonator you need to emit four signals with 1.2 second interval between them. +-0.3 second error is allowed and will still do the job. Disabled resonator will no longer emit any signals. Once all three of them are disabled the door will open.
