Problem Identification:
Many people have equalizers or bass and treble adjustments on their stereos at home and in the car, but what good can they do if the user is not an expert in interpreting sound quality. How can the user adjust different stereo systems to optimal sound quality? These are some of the problems we are going to solve in our audio testing circuit, which we have built for our senior project.
Idea/Solution
Our proposed idea is to build a Sound Pressure Level meter to help tune stereos and measure frequencies from a receiver and speaker setup. Once these frequencies have been inputted to the setup and the sound level is measured, this data will go into a 6811 and the measurements will compare to standard values. Some of the advantages of our project idea are to fine-tune a speaker without having to rely on the user’s audio perception, which will help improve sound quality of stereo.
