3.Results

                     


The results of our experiment are as shown below:



Table 1: Table of expected resonant frequencies and decibel of corresponding frequency




These are the decibel readings that we recorded down for the different frequencies
(highlighted shows resonant frequency in each test and their corresponding decibel)

 
Table 2: Table of frequencies against the decibel reading at that frequency




These are the frequencies that we concluded are resonant frequencies at 1m:
(highlighted shows resonant frequencies at 1m)
