Sound Basics
This is the medium most sound waves travel through in every day life
What is air?
This is the unit used to measure frequency.
This is the objective measurement of wave size or energy.
What is amplitude?
This term describes the collection and strength of all frequencies in sound.
What is spectrum?
This component of sound production provides airflow and energy.
What is breath?
Sound travels as these alternating high and low pressure regions.
What are compressions and rarefactions?
Frequency measures this: the number of these per second.
This is the subjective perception of amplitude.
What is loudness?
Timbre is often described using this two-word phrase.
What is tone-color?
These oscillate to create the initial pressure waves in the voice.
What are the vocal folds?
When particles are pushed together in a sound wave, this occurs.
What is compression?
This is the subjective perception of frequency.
What is pitch?
True or False: Frequency and amplitude are dependent on each other.
What is false.
What is timbre?
This part of the body shapes an amplifies sound.
What is the vocal tract?
When particles are spread apart in a sound wave, this occurs.
What is rarefaction?
A440 has this frequency value.
What is 440 Hz (A4)
Even if two sounds have the same frequency, changing this will make one sound louder.
What is amplitude?
The balance and intensity of these define timbre.
What are harmonics?
Smaller instruments emphasize these frequencies.
What are higher frequencies?
Speech and singing are described as this type of sound because they contain many waves at once.
What is complex sound?
These are whole-number multiples of the fundamental frequency.
This property varies between listeners even when amplitude remains constant.
What is loudness?
The harmonic series consists of frequencies that are this type of multiple of the fundamental.
What are whole number multiples?
Larger instruments emphasize these frequencies and tend to sound richer.
What are lower frequencies?
