This was my home speaker test during which I learned how to use a decibal meter. I tested three kinds of speakers that I had at my house: A pair of Bose speakers that were connected to my home computer, an older pair of Aiwa speakers that my brother has, and my iHome. The goal of this test was to take decibal readings from the speakers when different tones were played. After graphing the speakers, the one with the flattest line will resemble the best speaker because you want a consistent decibal readings at different frequencies. Of the three that I tested, I had one pair of speakers that really surprised me and two that didn't at all. I knew that the Bose speakers would be good because they are top quality and expensive speakers. I also knew that they Aiwa speakers probably wouldn't be very good because they are cheaper and have been in my brothers room for atleast 5 years. However, I was somewhat surprised by my iHome speakers. These speakers are speakers put into an alarm clock that has an iPod dock. I didn't expect a whole lot from these speakers but they actually did a great job. If I had to rate the speakers after my test based on how consistently flat their lines are, it would be Bose at number one, followed by the iHome, and then the Aiwa speakers.
The procedure for my test was:
1. Start with the decibal meter about 1 meter from the speakers, then play the 315 hertz tone and adjust the volume until it read about 85 Db.
2. I started with 50 Hertz and played all of the tracks through 18,000 hertz, recording the Db reading for each.
3. I did these steps for all three of the systems.
4. I graphed my data.
5. I sent my graph to my posterous
