Frequency & Amplitude Introductory Presentation

Opening Activity In Clap On, Clap Off, we used the LEGO Sound Sensor to control when our robot moved and stopped.

Opening Activity Answer the Following: 1. What is sound? 2. How does it travel? 3. How do we measure sound?

Review Sound is traveling energy which takes the form of regions of compressed air, soil, or whatever it’s traveling through.

Review We measure sound by some of its properties such as: • Wavelength • Frequency • Amplitude

Review: Wavelength If someone were talking to you, Wavelength would be the distance between the regions of compacted air that their voice is creating. Wavelength

Review: Frequency is a measure of how many of the compacted regions, or wavelengths, pass a certain point over an interval of time. Point

Review: Frequency The more wavelengths that pass in a set amount of time, the higher the frequency. The fewer wavelengths that pass in a set amount of time, the lower the frequency. Low Frequency High Frequency 1. 5 wavelengths 3 wavelengths

Review: Frequency We perceive frequency as the pitch of a sound. Thus, frequency determines how high or low a specific sound is. low notes = low frequency high notes = high frequency

Review: Frequency So would a soprano sing high frequency notes or low frequency notes? High frequency sounds If you listened to a bass player would you be hearing high frequency sounds or low frequency sounds? Low frequency sounds

Review: Amplitude, commonly referred to as volume, is a measure of how hard the compacted regions of energy are pushing into what’s in front of them.

Review: Amplitude The harder they push they louder the sounds. The softer they push, the quieter the sound.

Review: Graphing As a refresher on how to graph results, examine the chart below created with the included data. Data collected from experiment Recorded Measurement Trial 1 20 Trial 2 50 Trial 3 70 Trial 4 30 Data within a chart

Reminder One last thing! Make sure you have speakers connected to your computer, otherwise your robot won’t have anything to listen for.

Good Luck! Now you have the necessary knowledge to get started in the Frequency & Amplitude Activity.
