Isolation Testing Performed

Isolation testing was done at ExCite Center from 2-5 p.m. Vibrations were again measured using the Seismometer App. The two songs which featured heavier bass ("Hotel California" and "Heart of a City") were used for vibration testing. Testing was again done by placing an iPhone 5c on the base of the stand, and recording the vibrations detected while a track was playing. This time, the best design would be indicated by the least amount of vibration measured. This is because the isolation system, as its name indicates, is suppose to mechanically isolate the speaker from the stand. By definition, this meas that the best isolation system would absorb the most vibrational energy, thus giving the lowest vibrational reading at the bottom of the stand.
After this, the audio the speakers produced with each isolation system on the stand was recorded. This was measured with the Audio Recorder app on a Droid Turbo. The experiment was set up with the phone placed on an identical stand, centered on the edge nearest to the speaker of. The nearest edge stand itself was 2' from the forward-facing edge of the stand with the speaker on it, Forty seconds of each song was recorded as a 705 kbps .wav file for each isolation system. This will hopefully give some insight into which isolation system reproduced the audio most accurately.
