The hypothesis is that reducing the size of the speaker enclosure will cause the dB of some frequencies to be higher compared to the rest of the frequencies.

You will construct three speaker enclosures of different sizes using plywood, glue, and nails. You will then connect the speakers to a CD player and measure the decibel reading of various audio frequencies using a decibel meter.

You will need plywood, glue, nails, a drill, saw, decibel meter, CD player, and a test CD with various audio frequencies.

The results showed that the frequency response of the two larger speakers did not go beyond the 0 dB level, but the smallest speaker produced some frequencies that were louder than the others. This type of air tight speaker enclosure is called a sealed enclosure and can produce more precise sound.

This science project is interesting because it shows how the size of a speaker enclosure can affect the sound it produces.

Experiment variations could include checking the frequency response using different types and thickness of wood for the enclosure, or using different sizes of speakers.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
