Recorder Problem Solving

During the tests run in the previous lab, it was found that the quality of sound was poor, screechy like child learning the recorder and not an instrument fit for a symphony. The first proposed solution was changing the air pressure released from air compressor, however after this failed to solve the problem, we moved on to investigating the seal of the solenoids over the holes of the recorder. This led us to use foam earplugs instead of the original rubber stoppers to ensure a better seal over the holes.
