Description | ||
This experiment was done to investigate how the frequency response of a speaker will change using different sizes of enclosure. | ||
Instructions preview | ||
1. For this experiment, the independent variable is the side of the enclosure and audio frequency played. The dependent variable is the decibel reading of the frequency. The reading is measured using a Decibel meter. The constants (control variables) are the materials used to construct the speaker, the size of the speaker and the distance of the decibel meter from the speaker. 2. The plywood planks are cut and constructed according to the speaker enclosure sizes shown in figure 2. The speakers are marked A for 500mm depth, B for 400mm depth and C for 300mm depth.
