5.7 Musical Sounds Flashcards
What is the relationship between the frequency of the wave and the pitch of the note?
The higher the frequency, the higher the pitch
What does the volume of the note depend on?
The amplitude of the sound waves
What is the relationship between the amplitude of a sound wave and the volume of the note?
Bigger amplitude means the wave carries more energy so the volume is louder
Where can differences in waveform be seen?
An oscilloscope
Name 2 things that produce pure waveforms
- tuning forks
* signal generators
What does the quality of the note depend on?
The waveform
Why do instruments sound different to each other?
They produce different waveforms
What produces musical sound waves?
Vibrations in the instrument when it is played
How does a saxophone produce sound?
A column of air vibrates
How does a violin produce sound?
The strings vibrate
How does a xylophone produce sound?
The keys vibrate when they are struck
Why do different instruments sound different when they play the same note?
The waveforms are different
What is resonance?
When something vibrates at a frequency that makes it physically move
When can resonance be dangerous?
Suspension bridges
What is the relationship between temperature and sound speed?
The warmer the air, the faster the sound is
