We use a logarithmic scale when there is a wide range of values, and when a change in a value depends not on the absolute size of the change but on proportion to the value itself. Adding 1 to a value is absolutely the same whether the original value is 1 or 1000, a linear scale makes sense. If doubling a value is just the same change whether is it from 1 to 2 or from 1000 to 2000, a logarithmic scale is appropriate.
We are going to investigate the decibel scale for loudness. There are two reasons why a logarithmic scale is useful:
Quantities of interest exhibit such ranges of variation that a dB scale is more convenient than a linear scale. For example, sound pressure radiated by a submarine may vary by eight orders of magnitude depending on direction.
The human ear interprets changes in loudness within a logarithmic scale.
What else can I help you with?
Another term referring to loudness or volume is?
If you are referring to loudness of sound, then 'decibel' is a way of describing the loudness of sound. Rise in 10 decibel should mean rise of about 10 folds the initial level.
What property of sound describes your awareness of the energy of a sound?
Loudness is the property of sound that describes our awareness of the energy of a sound. It is subjective and depends on the amplitude of the sound wave.
How is loudness of sound determined?
The loudness of sound is determined by the amplitude of the sound wave. A larger amplitude produces a louder sound. Decibels (dB) are used to measure loudness on a logarithmic scale.
What is loudness of sound determined by?
The loudness of sound is determined by the amplitude or intensity of the sound wave. Greater amplitude or intensity results in a louder sound. The unit used to measure loudness is decibels (dB).
What is brightness as sound is to light?
Loudness is to brightness as sound is to light.
Another term referring to loudness or volume is?
If you are referring to loudness of sound, then 'decibel' is a way of describing the loudness of sound. Rise in 10 decibel should mean rise of about 10 folds the initial level.
What property of sound describes your awareness of the energy of a sound?
Loudness is the property of sound that describes our awareness of the energy of a sound. It is subjective and depends on the amplitude of the sound wave.
What determines the loudness of sound waves?
The amplitude determines the loudness of a sound wave.
Loudness is the human perception of sound wave?
The amplitude of sound waves is what humans perceive as loudness.
How is loudness of sound determined?
The loudness of sound is determined by the amplitude of the sound wave. A larger amplitude produces a louder sound. Decibels (dB) are used to measure loudness on a logarithmic scale.
What is loudness of sound determined by?
The loudness of sound is determined by the amplitude or intensity of the sound wave. Greater amplitude or intensity results in a louder sound. The unit used to measure loudness is decibels (dB).
What is brightness as sound is to light?
Loudness is to brightness as sound is to light.
On what factor the loudness of sound depend upon?
The loudness of a sound depends on the amplitude of the sound wave. A higher amplitude corresponds to a louder sound. The human perception of loudness also depends on the frequency of the sound wave and the sensitivity of the human ear.
Is the loudness of a sound is called its intensity?
Yes the loudness of a sound is called its intensity.
What unit of sound loudness?
The unit of sound loudness is the decibel (dB). It is a logarithmic scale that measures the intensity or volume of sound.
What part of a waveform describes a sound's loudness?
The amplitude of a waveform describes a sound's loudness. The greater the amplitude, the louder the sound.
How does amplitude affect the loudness of a sound?
it is how loud the sound is ^Smartass comment. The real answer: Loudness is determined by the intensity of sound waves.
