The only Microphone I can think of with a good frequency respone at that frequency level is the:
ElectroVoice N/D767a N/DYM Professional MicrophonePolarity Supercardioid Frequency Response 35 - 22000 Hz Impedance 300 ohms Effective Output Level -51 dBm2500000 - 2200000 = 300,000
Headphone Response Bandwidth: 60 - 16000 Hz. Microphone Response Bandwidth: 100 - 10000 Hz
Frequency range is from60 Hz to 20 kHz.

A frequency analyzer would be more accurate at analyzing frequencies like 500 Hz and 5000 Hz compared to a standard microphone or sound level meter. Frequency analyzers are designed to specifically measure and analyze different frequencies accurately.
The roll off filter removes low frequencies. Usually at about 75 HZ and bellow.
10% of 2,200,000 is 220,000
2,200,000 multiplied by 5,100 = 11,220,000,000
183.3% of 2,200,000 is 4,032,600
