SF Blog B: Science Proposal

1. What is your topic? Car Audio
2. What is the driving problem behind your experiment and the quote by an expert to support that problem? Audio distortion and power loss are key problems in car audio.
3. What is your hypothesis? Power loss and audio distortion in car audio are directly correlated and can both be solved by sharing a single answer.
4. Science Fair Proposal: A major issue in car audio is power loss and audio distortion. I belive their may be a direct corralation with these two issuses, to little or to much power for the amplification causing distortion. I plan to approach these both issues and attempt to solve them both or simply reduce them both by solving for them at the same time, dirrectly corralating them together and using one solution for both. A lot of this project will be experimentation, with many amplifiers and speakers, i will also need a decibel reader and a multimeter for measurement of power and distortion.
5. Project Category for experiment: Engineering Research & Applications

SF Blog A:Problem Statement

1. Topic:

• My topic is Car Audio, this includes, the voltage provided to the audio equipment, the head unit, speakers, amplifiers, and other installations made for improving sound quality.

2. Problems:

• A major problem in car audio, is distortion of sound, this occurs in the process of amplification.
• Another problem is audio feedback, this occurs a lot with bluetooth, audio control, and amp to head unit feedback.
• A problem that only occurs in larger sysetems is lack of voltage provided by the automotive battery, this occurs when the system drawls more voltage than the alternator can charge.

3. What will be done upon the discovery of solutions:

• The first thing I would do once any of these problems are solved, is let any fellow installer know and implement the solution into instalation jobs. I would later inform the customer on the solution, and the only real way for my solution to be widely known, is to post solutions on forums and web pages of such.
