This unfiltered data is the frequency response of a pubilshed subwavelength resonator design, [Online link: ], within a bandwidth of 120Hz - 600Hz. The predicted resonant frequency is 198Hz and the expermental data supports this with an error margin of 11.7Hz. The excitation signal was a swept sine wave with a peak amplitude of +/- 1.5V throughout. This can be used to calulate the Transmission Loss of the resonator. Data_measurements1 is the recorded resonator response, whereas Data_measurements2 is the microphone noise, to help filter out the noise from the first dataset.
