How 'bout drums?
Sound waves travel through the air and interact with the human ear.
(Sound waves - sound waves - sound waves - sound waves)
Sound waves beat against this membrane as drum stick beat upon a kettle drum or timpani.
Thus producing the complex sound of speech and song.
As I speak, the sound waves produced by my voice are transmitted through the air to the microphone, where these sound waves are converted to changes in an electric current.
Sound is all around us.
And remember that all sound is vibration.
And it is amplitude that determines loudness. (Loudness - loudness - loudness - loudness)
A piano covers a frequency range of 55 to 8,360 hertz. This type of sound is complex.
Noise requires the judgement of a human listener. Noise is defined as any unwanted sound.
When the vibrations or sound waves stop, the ear is exactly as it was.
The pattern of the sine wave repeats itself periodically.
Sound waves must propagate through some medium.
Say, a little percussion?
The loud speaker converts the varying electrical current into sound waves. All sound waves entering the ear are converted into nerve impulses. The ear, then, is a very delicate and complicated mechanical device.
And no tuning is ever required.
You could vary the harmony; change the tone color according to your taste.
Noise requires the judgement of a human listener. Noise is defined as any unwanted sound.
Acoustics and your environment; the threshold of pain for humans is between 130 and 140 decibels.
Differences in the audible components of a sound determine its quality.
Loudness, pitch and quality.
Sound travels the distance of one wavelength, which transforms sound waves into the sensation of hearing.
Here's another example of pitch or frequency.
A piano covers a frequency range of 55 to 8,360 hertz. This type of sound is complex.
A higher amplitude equates to a higher volume; on this scale the unit is the decibel.
Sound waves beat against this membrane as drum stick beat upon a kettle drum or timpani.
Thus producing the complex sound of speech and song.
Acoustics is the science of sound. This is termed; the acoustic pressure.
So, we've covered what musical tone is, and how it's generated.
There's a whole lot more to know about sound if you really want to go into the subject.
