How does a volume knob work or what happens to make the sound increase when the knob is turned?
They key to volume control is a variable resistor.
A variable resistor uses a resistance track with connections at both ends. There is wiper that moves along the track as the volume knob is turned. The tracks are usually rotary for volume knobs, or tracks for volume sliders.
The variable resistor may be used as a rheostat, which means that only two terminals are used (the wiper and one end of the track). By turning the knob, the wiper sweeps across the track, which will effectively vary the resistance from 0 to maximum. A rheostat is usually used to vary current so they would be useful for varying the brightness of a lamp. A variable resistor can also be used as a potentiometer, which uses all three connections (both ends of track and wiper). If you connect the track terminals across a power supply, then the wiper terminal is used to provide a voltage, which can be varied from 0 to the maximum (the supply voltage). Potentiometers are usually used for amplifiers.
Hope this helps

What happens to volume as decibels increase?
More decibels means that the sound volume increases.
When you turn down the volume what happens to the sound waves' amplitude?
Intensity of sound is dealt as volume in case of radio sets. Intensity is directly proportional to the square of amplitude. So as volume is turned down, intensity is reduced and so the amplitude is decreased.
Which property of sound waves changed when you increase the volume on a car radio?
The amplitude of the sound waves increases when you increase the volume on a car radio. Amplitude is directly related to the loudness or volume of the sound.
How do you increase the intensity of sound waves from a radio?
Increase the volume.
What is when volume levels increase does wavelength increase?
When volume levels increase, the amplitude of sound waves increases, but the wavelength remains the same. Wavelength is determined by the frequency of the sound wave, which is not affected by changes in volume.
How can you increase volume of sound of nokia 6020?
how do i increase the volume on my nokia 6085. I can barely hear it when it rings
What do you need to do add to make a sound louder?
To make a sound louder, you can increase the volume on the device playing the sound or adjust the sound settings to maximize volume. You can also try using external speakers or headphones to amplify the sound further. Additionally, editing the sound file to increase its volume level is another option.
What happens to the volume of sound as the amplitude get larger?
The greater the amplitude of a sound wave the louder the sound.
What happens to volume as amplitude gets higher?
As the amplitude of a sound wave increases, the volume or perceived loudness of the sound also increases. This is because higher amplitudes result in greater variations in air pressure, leading to more intense vibrations that our ears interpret as louder sounds.
I have picture but no sound what do i do.?
Increase the volume. Failing that, buy a new set.
How to turn up volume on speaker?
To increase the volume on a speaker, you can typically adjust the volume using the controls on the speaker itself or by using the device connected to the speaker (such as a phone or computer). Look for buttons or knobs labeled "volume" and adjust them to increase the sound output. If your speaker is connected to a device, you can also adjust the volume settings on that device to increase the sound.
What are multiple objects that you have that allows you to increase the volume of a sound?
Some objects that can increase the volume of a sound include speakers, amplifiers, and megaphones. These devices take the audio signal and amplify it to produce a louder output.
