Exploring the 7 Key Characteristics of Sound Waves

Dive into the fascinating world of sound waves with an exploration of their 7 essential characteristics. Learn about attributes such as amplitude, frequency, phase, velocity, wavelength, harmonics, and envelope (ADSR), each playing a crucial role in shaping how we experience and interpret sound. Understand how these characteristics contribute to the richness and diversity of sounds we encounter in our daily lives.

1. 7 Characteristics of Sound

2. Amplitude Height of a sound wave Measured in decibels (dB) Often referred to as volume

3. Frequency Completion of one cycle Measured in Hertz (Hz) Related to pitch (Middle C 262Hz)

4. Phase Designates a point in a sound wave s cycle Measured in degrees Two waves in phase equal increased amplitude Two waves out of phase equal decreased amplitude

5. Velocity The speed at which sound travels 1130 feet per second @68 degrees F Faster as heat increases

6. Wavelength The physical length of one completed cycle Wavelength = Velocity divided by Frequency 1130/30 = 37.66 ft

7. Harmonics Often referred to as timbre Divided into evens and odds Helps us differentiate one instrument from another

8. Envelope ADSR Attack Decay Sustain Release Helps us differentiate one instrument from another
