Students learn about sound with an introduction to the concept of frequency and how it applies to musical sounds.

Frequency is a important to understand for engineering purposes. For example, an engineer might need to know how often something happens or how often something should happen. Engineers use their knowledge of frequencies to design many commonly used items: lights, televisions and even traffic signals, which are specifically programmed to start or stop according to traffic patterns. Frequency is also an important part of music, as notes with different frequencies make different sounds. Acoustic engineers help design auditoriums that enable everyone to hear the music produced on stage. Explain frequency.Give an example of frequency.Explain that different frequencies of sound waves produce different sounds.20TeachEngineering.orgJessica ToddBrad DunkinLuke SimmonsChris YakackiBrian KayFrank BurkholderAbigail WatrousJanet Yowellhttp://www.gmi.edu/~drussell/Demos.htmlhttp://www.smm.org/sound/nocss/activity/handson.htmS11416DAInternational_Technology_Education_Association-ITEA_STL_StandardsTechnologyC.
