Executive Summary

Test for loudness and noise levels of our Smarthorn iphone speakers. Tests were carried out in a room without background noise e.g. air-condition etc. I have conducted the test with two different noise results.

                1) Using audio tester close to the speaker

                2) Using the audio tester from 20 cm away from the speaker

The music played before it was placed on the speakers is measured as follows:

Close to iphone 20 cm apart from the speaker Average Noise in dBA
Max 89 dBA  /   Min 76 dBA Max 78 dBA  /   Min 68 dBA Max 84 dBA  /   Min 72 dBA
