Sound. Reverberation. Echoes may be heard more than once due to repeated or multiple reflections of sound from several reflecting surfaces. This causes persistence of sound called reverberation. . Sound. Reverberation.
Sound. Chapter 15. Properties of Sound. Properties of Sound Waves. Sound is a compression wave in any material medium oscillating within the frequency range of 20 Hz to 20 kHz. Sound waves are longitudinal and can propagate as a sphere in an elastic medium such as air.
Sound. AP Physics B Chapter 12 Notes. Sound Characteristics. Sound is carried by longitudinal waves The speed of sound varies with media In air v = 331 + 0.6T where T is temperature in ˚C. Sound Characteristics. Loudness depends on intensity/amplitude Pitch depends on frequency
Sound. Characteristics of Sound Mathematical Representation of Longitudinal Waves Intensity of Sound: Decibels Sources of Sound: Vibrating Strings and Air Columns Quality of Sound, and Noise; Superposition Interference of Sound Waves; Beats. Doppler Effect
Sound. Sound waves. Sound waves are longitudinal waves They cause particles of air to vibrate back and forth. A medium must be present in order for a sound wave to be heard. Properties of Sound Waves. Sounds waves have all the properties of any type of wave velocity Reflection Diffraction
