I had the almost exact same problem with my 2004 Nissan Maxima. after several trips to the dealership for all kinds of tests and inpections(most of which involved brakes) the technicians told me my rim was bent. A new one cost 700 bucks on my car. I don't know how to check for that without giving it to a tire shop.
The faster the vibration, higher the pitch.
The plucking of the strings causes the sting to vibrate - the longer the string and smaller diameter the higher the tone produced.
Most commonly a vibration while driving is from a broken belt in one of the tires, but if it's vibrating while sitting still, it's usually from loose motor mounts and/ or a higher than necessary rpm
Sound is the vibration of air molecules. The higher the pitch, the faster the vibration. The stronger the vibration, the louder the sound.
it depends on how big or small the vibration is to determine the sound. The bigger the vibration, the lower the sound is. the smaller the vibration, the higher the sound.
With your ears. The faster the vibration, the higher the frequency. A low frequency vibration will be felt more than heard.
Sounds (all of them) are produced by vibration. The faster the vibration, the higher the pitch. Whether the vibration is produced on a string or with air, it's the speed of the vibration, and the length that vibration has to travel that determines the pitch.
Increase the frequency of vibration.
Sound is created by the vibration of air. The faster the vibration, the higher the sound. Smaller objects can vibrate faster than larger objects (of the same kind) and therefore have a higher pitched sound.
The timing is set higher than recommended. It needs to be retarded.
Since our ears recognize any type of pitch as a vibration the more vibration the higher the pitch less vibration lower the pitch.
No. If a vibration is smaller, the sound is higher pitched. To get a quieter sound the amplitude of the sound-wave needs to be smaller. +++ It depends whether you mean amplitude or wavelength being "smaller", and they are two different things. If the vibration's amplitude is smaller the sound is quieter irrespective of frequency. If the vibration is more rapid, the frequency is higher but the wavelength correspondingly smaller irrespective of amplitude.
