It was when the air hit the wave and it move to another direction
the pitch gets higher as you tighten
When the train gets close to you the sound wave are compressed making a higher pitch noise and as the train passes the sound waves become lengthened. That is the doppler effect in a nutshell. Now just compare it to how the doppler effect changes light waves.
That depends on the nature of the medium through which it is traveling and how that medium's density is affected (if it is affected at all) by its change in temperature. The denser the medium, the faster sound travels through it. For example, in a sealed chamber containing a gas, the speed of sound is not affected by temperature unless it gets cold enough for the gas to condense to a liquid. As long as it remains a gas, changes in temparature only affect its pressure, not its density.
its cause when you go down the air gets to thin and you get all happy and ur voice gets hi
sound is a mechanical wave.Sound can be of two types :music and noise. sound gets reflected. we need about 300 metres for a good echo to be heard. there are audible and inaudible sounds. audible from 20Hz to 20000Hz.below 20Hz and above 20000Hz are inaudible sounds.There are infrasonic and ultrasonic sounds.
The two properties of a sound that get louder are its amplitude, which determines the volume or intensity of the sound, and its energy level, which increases as the sound becomes louder.
It gets louder or quieter.
It means that the amplitude of the soundwaves is increased, or is increasing if the sound continues to get louder.
Can anyone help me? "How can you change sound?" is my question and when I type it up in the question box, it says 'Contributors have said that "How can you change sound?" is the same question as "What could this sound be when I am accelerating I hear a bit of a whinding sound and obviously when I speed up and change gears the sound gets a little louder and louder. Also, my clutch squeeks?" Who ever said that those to questions are the same is an idiot. This certainly doesn't help me with my homework!:( I'm very sad now!
Amplitude = "Loudness" In that a direct increase in amplitude will cause the sound to be "louder".
the sound gets louder
The amplitude (The height of the wave) of the wave increases as the sound gets louder.
Its wavelength increases and its frequency decreases
Frequency and wavelength of the sound wave change when pitch gets higher. A higher pitch corresponds to a higher frequency and shorter wavelength in a sound wave.
It gets louder and then gets quieter
As sound gets louder, the ear drum vibrates more forcefully. If the sound is extremely loud, the ear drum may reach its maximum vibration capacity, leading to potential damage or tearing. This can result in hearing loss or other ear-related issues.
baffles corrode, filling shrinks and gets pulverised, so the sound gets louder, and back-pressure drops. in short, it's wear-n-tear.
